The Respiratory and Circulatory Systems Essay
1. Explain how the respiratory and circulative systems coordinate the supply and conveyance of O to the cells and remotion of C dioxide from the blood. ( 10 Marks ) Paragraph 1: What happens in the respiratory system?Respiratory System: Organizing the Supply and conveyance of Oxygen* Oxygen is inhaled through the olfactory organ or oral cavity* Travels down through the Pharynx* Travels down the Larynx* Reaches the lungs and goes through the Bronchi* Through the Bronchioles* Then reach’s the Alveoli* The Oxygen so leaves the lungs and is transported around the organic structure via blood vass* Deoxygenated blood carries the Carbon Dioxide back to the lungs* The deoxygenated air so retraces its stairss* Back to the Alveoli* To the Bronchioles* Through the Bronchi* Through the Larynx and Pharynx* Then eventually out of the olfactory organ or oral cavity.Paragraph 2: Circulatory SystemBlood transit– The bosom sends blood around your organic structure. The blood provides your organic structure with the O and foods it needs. It besides carries off waste such as C dioxide.
-Your bosom is kind of like a pump. The right atrium of your bosom receives de-oxygenated blood from the organic structure and pumps it through the valve to the right ventricle. back to the lungs so that it can be re-oxygenated. -The left atrium receives blood from the lungs where it is passed through another valve into the left ventricle so pumped out into the organic structure. – Blood is pumped and circulated through the organic structure via blood lieges.
– Angrownup has an norm of 5 litres of blood in the organic structure ; the circulatory system carries this full measure on one complete circuit through the organic structure every minute. -It equalizes organic structure temperature and helps keep normal H2O balance.Paragraph 3:How is it possible? What allows it to go on?+The Pharynx has hairs to filtrate air.+The Trachea is lined with mucous secretion releasing cells.+Bronchi and Bronchioles get air deep into the lungs.+Alveoli has thin walls to let air to go through back and Forth.
