Question 8

Cardiac Output

Answer 8

provides efficient blood flow to all tissues of the body

Question 11

Why is coronary circulation important?

Answer 11

ensures a fresh supply of oxygen goes to the heart muscle and so the coronary arteries receive blood with each beat

Answer 24

relax blood vessels and reduce pressure
