Explain how the respiratory and circulatory systems coordinate the supply and transport of oxygen to the cells and removal of carbon dioxide from the blood. (10 Marks) Paragraph 1: What happens in the respiratory system?
The heart sends blood around your body. The blood provides your body with the oxygen and nutrients it needs. It also carries away waste such as carbon dioxide.
-Your heart is sort of like a pump. The right atrium of your heart receives de-oxygenated blood from the body 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 then pumped out into the body. – Blood is pumped and circulated through the body via blood vassals. An
adult has an average of 5 liters of blood in the body; the circulatory system carries this entire quantity on one complete circuit through the body every minute.
-It equalizes body temperature and helps maintain normal water balance.
