|
Definition
| is to channel blood to organs and tissues to ensure oxygenation and metabolism |
|
|
Term
| How is the blood pressure in the arteries maintained? |
|
Definition
| As the ventricles contract during systole, blood is quickly sent into the aorta which forces the expansion of the vessel wall. When the aortic valve in the heart closes and diastole ensures, the arterial wall recoils o release stored energy. The recoiling of the wall forces the blood to continue its forward movement and therefore blood pressure is maintained |
