1) how is arterial blood pressure maintained while the heart is relaxed?
2) Explain how the heart pumps blood in an efficient and orderly fashion?
Homework Answers
Arterial blood pressure is maintained in the following ways:
- The aortic valve is closed at the proximal end of the aorta end. This prevents the backward flow of blood into the heart.
- The outflow of blood into the venous pool is restricted.
The walls of all the blood vessels exert pressure on the arterial blood in them. This is the origin of the pressure which pushes blood from heart to capillaries.
