Question 3

Question 17

What is the purpose of the heart

Answer 17

The heart’s purpose is to transport blood with oxygen to the cells of the body and blood low in oxygen to the lungs to receive oxygen.

Question 18

What is the difference between the pulmonary circuit and the systemic circuit?

Answer 18

In the pulmonary circuit blood low in oxygen is pumped to the lungs to receive oxygen and give up carbon dioxide, blood high in oxygen returns to the heart. This called lung circulation. Where in the systemic circuit blood rich in oxygen is pumped to the rest of the body where oxygen is given up and carbon dioxide is picked up. This blood goes back to the heart to be pumped back to the lungs.
