The Integumentary Organ System Biology Essay

The integumental system is the organ system that is made up of the tegument, which can be hair, feather, nails, and graduated tables. The integumental system is critical to an being because it acts as a shield and protects the being from the outside environment like the conditions, infective beings and Acts of the Apostless as an touch and hurting receptor. The integumental system consists of three beds: the cuticle, corium, and hypodermis.

The integumental system is different for the four dissection animate beings. The angleworm has a moist, lubricated organic structure to assist it tunnel through the Earth. The spiny lobster has a difficult exoskeleton, which truly really different integumentary system than the other beings, to protect itself from crisp objects and other marauders. The grass toad has skin, which is rainproof to avoid H2O loss and desiccation. Last, the white rat has a short length of pelt on the cuticle to help it in keeping homeostasis by modulating temperature.

The advantages of these assortments in the organisms depend on the environment they live in. For illustration, the grass toad has a moist waterproof bed of tegument because it lives in a wet home ground such as a pool or lake. This allows it to travel in the H2O and come up on dry land if needed. The tegument allows adequate H2O to osmose into and hydrate the organic structure but keeps extra H2O out. Some disadvantages of moist teguments are that beings will necessitate to remain near beginnings of H2O or else they will acquire dehydrated and decease. The angleworm who lives belowground relies on its moist tegument to be able to travel through the dirt. It besides has the ability to make lubricating liquid which helps it move. An advantage it has is because it ‘s segmented, it is really flexible. However, the disadvantage is its size. Because the angleworm is so little and has little to no protection because of its thin bed of tegument, it can easy be crushed by other animate beings. The crayfish relies on its difficult exoskeleton shell for protection. It has bantam small hairs on its legs that can feel motions in the H2O. The disadvantage of the spiny lobster is that one time the shell is gone, it will be exposed to danger and easy killed. The rat with its pelt on top of a thin bed of tegument can maintain warm. It has beards on its neb and nails on its pess and the tail has rough hardened tegument. A disadvantage could be wet pelt can take down its organic structure temperature. Besides, with mouse traps like gluey 1s, it can pin down the rat because of its pelt.

As development made alterations, it required new signifiers of integumental systems. The first signifiers of animate beings which were fish were inhuman and up to the reptilians, they all had either graduated tables or moist tegument. As the earliest animate beings, they lived in the H2O and their graduated tables confined them to the H2O. The amphibious vehicles lived largely on H2O but were able to come up to dry land but non for long. The first category of animate beings that were warm-blooded are birds. They needed a manner to maintain a temperature that is at their homeostatic degree so they have plumes. This helped them maintain warm and besides allowed them to wing. In mammals, which are besides warm-blooded, have fur or hair. This allows them to maintain warm and maintain homeostasis. The disadvantages of furry animate beings are if there is a sudden alteration in conditions like a heat moving ridge, so thickly furred animate beings will decease from the heat.

The integumental system is a critical portion of an being which has its advantages and disadvantages depending on its environment.

Muscle and Skeletal System

The musculus system is the organ system which allows an being to travel. In craniates, the musculus system is controlled by the nervous system. There are three types of musculuss which are: skeletal, cardiac, and bosom musculuss. The musculus system is really of import to an being because it provides strength, position, and the ability to travel for an being.

The skeletal system is the ground why an animate being has its signifier and form. It besides acts as a protective coop for all the of import and critical variety meats in the organic structure. Besides, it allows beings to travel the manner they do. There are three different sorts of skeletons. The first 1 is an endoskeleton. An animate being with an endoskeleton has a skeleton inside its organic structure like a human being. The 2nd is an exoskeleton, which occurs in animate beings like pediculosis pubis. Last is a hydro skeleton, where there is n’t truly a skeleton but is a fluid-filled pit.

In our dissection animate beings, we can see that there are many differences in the animate beings musculus and skeletal system. The worm has a hydro skeleton organic structure and it relies on its musculuss to be able to travel about by utilizing muscular contraction. The worm has an advantage because it has a hydro skeleton which allows it to be really flexible. Development likely played a function in giving the angleworm an astonishing ability. It has the power to renew lost sections in its organic structure. It has great anabolic capablenesss in its musculuss, and in any instance that it loses a twosome of sections, so it can merely renew it back. This can do up for its weak skeleton. Its disadvantages are it can easy be crushed because of its weak skeleton. In the spiny lobster, it has a exoskeleton which gives it good protection. Evolution played a function in doing them hold difficult exoskeletons to last in competitory Waterss. Besides, because it has an exoskeleton it is an advantage and disadvantage. With its exoskeleton it has better protection but when it molts, it will be at its most vulnerable to marauders and danger. The spiny lobster is divided into two sections: which are the venters and cephalothorax. It relies on its musculuss in its eight legs used for traveling about and a brace of strong tweezers for acquiring nutrient, assailing and supporting itself. Besides, it has a tail which is used to impel itself frontward. The toad has a endoskeleton. It has long back legs that allow to them to jump, leap, and swim off from danger. I believe that development has made toads have strong powerful legs. Its long thighbone and powerful thighbone and tibias play a function in their endurance. Last but non least, there is the rat which has a endoskeleton. The rat is similar to the toad but has smaller arm and leg castanetss and musculuss. The rat relies on strong incisors and musculuss for gnawing. Evolution played a function in rats because they must accommodate to their nutrient beginning. Therefore, they must hold incisors which are accustomed to their nutrient beginning.

One last thing is the differences between invertebrates and craniates. Invertebrates are animate beings which have no back bone and craniates do. The worm and spiny lobster are invertebrates while the toad and rat are craniates.

The musculus and skeletal system are of import to beings because they give them their signifier and form and the ability to travel. Besides those two systems help them last in their environments.

Digestive System

In all animate beings, the digestive system is an of import system that breaks eaten nutrient down into little adequate pieces in order to spread into the cell and do fecal matters as a manner to acquire rid of the waste from digestion. This system is made up of the oral cavity, gorge, tummy, and the little and big bowel, rectum, and in conclusion the anus.

Get downing at the oral cavity when you smell the good nutrient, your oral cavity will let go of an enzyme called salivary amylase that will lubricate the nutrient so it will be able to travel down the gorge. After masticating and the nutrient is drenched in the amylase, it will travel down the gorge. The gorge is the tubing like construction taking from the oral cavity to the tummy. The tummy is the organ that shops nutrient, contains katabolic enzymes and produces acid to interrupt down the nutrient, and is responsible for killing bugs in the nutrient we eat. When it leaves the tummy, the nutrient would be in a liquid signifier and be able to come in the little bowel. There, the little bowel will complete the digestion procedure started by the tummy and farther interruption the nutrient down by the katabolic enzymes. Once the nutrient is broken down into either disaccharides, fats, nucleic acids, or any smaller signifier, it will be absorbed and enter the blood watercourse straight into the cells to be used as energy. In the big bowel, any unabsorbed nutrient, waste stuff, will be formed into fecal matters. Besides, it will resorb H2O and assist make new “ good ” bacteriums. Last, the fecal matters will go out the organic structure by the rectum, so out the anus into the environment.

In the angleworm, we see a difference in the digestive system. It has a oral cavity, gorge, but a harvest and ventriculus. The harvest is where the swallowed nutrient are stored. The ventriculus is where all the nutrient are broken down. Because the angleworm has no dentition, it uses stones that were swallowed and its strong musculuss to interrupt down the nutrient. It goes through the remainder of the digestive procedure and the fecal matters exit through the anus. For the spiny lobster, it uses its mandible and upper jaws to take nutrient in. It goes through the gorge and into the tummy. The crayfish ‘ tummy is specialized to crunch nutrient up to be digested. It goes through the bowels, rectum, and in conclusion, out through the anus. In the toad, its long lingua bits prey into its oral cavity, nevertheless it has weak maxillary dentition. It has the same digestive variety meats. The rat, has the same digestive variety meats as the toad. However, the liver is the largest organ in the rat.

I believe for the rat, development made the rats liver larger because as rats became situated in the industrial and urbanised environment, it had to accommodate to the new nutrient beginnings, like rubbish and dirty nutrient. Therefore, the liver became of import in order for the rat to safely eat the nutrient and non acquire drunk or ill.

The digestive system is of import to organisms because without them, there would be no manner for them to last as they wo n’t be able to supply foods and energy to their cells.

Respiratory System

The respiratory system is the system in animate beings which is responsible for conveying in fresh O to the lungs and to take a breath out C dioxide. This system is made up of the olfactory organ, oral cavity, windpipe, bronchial tube, lungs and stop. In fishes they contain gills, and in some beings, they do non hold any respiratory variety meats and utilize the tegument to take in O.

When animate beings breath in, O would travel into the nose so oral cavity. The air travels down the windpipe and so into either the left or right bronchial tube so into the bronchiole tubing, which so leads into the lungs. The O would so make full up bantam pouch called alveoli. As blood flows through the capillaries, O will so spread into the blood, and C dioxide diffuses into the air sac and travel out the respiratory system.

In our dissection animate beings, we see a assortment of differences. In the angleworm, it does non possess any signifier of respiratory variety meats. It merely takes in O through the tegument and in return expels C dioxide with the same method. In the spiny lobster, its gills are responsible for acquiring O. Gills act as filters that pushes H2O out and pin down the O from the H2O. The O is so able to spread into the blood stream and the C dioxide diffuses out. For the grass toad, it works the same manner as the angleworm. However, in its early phases of life which is being a polliwog, it has gills. In its grownup phase, it will be able to utilize its lungs and besides take in O by absorbing O through its tegument. In the rat, it is similar to a human being. It will take a breath in O through its nose so go into the windpipe, bronchial tube, bronchiole tubing, into the lungs, in the air sac, exchange gases, so the CO2 will go out out the system.

The differences in variety meats can associate to development. For illustration, when the toad evolved into its amphibian province, it needed to be able to take a breath on land. Therefore, it went from gills, to lungs when it morphed into its grownup phase. I do n’t believe the angleworm and crayfish had any minor alterations in their system because they have been on this planet for a long clip and their environments do non necessitate them to hold any versions.

Therefore, the respiratory system is a critical system to organisms because they are responsible for taking and interchanging the gases O and C dioxide in our organic structure.

Circulatory System

The circulatory system is responsible for go arounding oxygenated blood throughout the organic structure. The bosom is the chief organ which is responsible for this, and is besides the 2nd most critical organ in the organic structure.

The procedure of which blood travels throughout the organic structure is first come ining the right atrium, so down into the right ventricle, so into the lungs. As O diffuses into the un-oxygenated blood by go throughing the air sac, it travels back into the left atrium and down the left ventricle so out into the aorta for the whole organic structure.

In our dissection animate beings there are many differences in their circulatory system. The angleworm has five Black Marias in entire. It has long blood vass to transport blood throughout its organic structure. In the spiny lobster, it merely has one bosom and is a two chambered bosom. Blood vass besides bring blood throughout its organic structure. In the toad, it has one bosom and has three Chamberss. Blood vass and arterias bring the blood throughout the organic structure. Last, the white rat has one bosom and is a four chambered bosom. Blood vass and arterias carry the blood throughout the organic structure.

The advantages of the different chambered Black Marias are that the more Chamberss there are, the more O will be available to the blood. The disadvantages are there is less oxygen available for the blood to transport ; for illustration, the toad has a three chambered bosom. In the ventricle, the oxygenated and un-oxygenated blood will acquire assorted and hence, carry less O. I think that development played a function in germinating the being ‘s Black Marias, because animate beings like the rat that require speedy motion, needs more than two Chamberss to supply sufficient O throughout the organic structure to map at its best.

In decision, the circulatory is a critical organ in an being which provides oxygenated blood throughout the organic structure.
