Which is the main function of the vena cavae?
A.) Carrying blood away from the heart
B.) Safely transporting blood to the heart
C.) Systemic blood pressure regulation
D.) Vasoconstriction and vasodilation
Homework Answers
Option B is correct (Safely transporting blood to the heart).
There is two vena cavae in body one is superior vena cavae and one is inferior vena cavae. Superior vena cavae carry deoxygenated blood from upper half of body(head, neck, arm and chest region) to the right atrium of heart. Inferior vena cavae carry deoxygenated blood from lower part of the body(abdomen, pelvis, and lower limb) to the right atrium of the heart.

Read the following scenario Blood flowing away from the heart is under tremendous pressure, able to travel to just about any portion of the body. however, blood pressure drops considerably as it moves away from the heart. When blood finally reaches capillaries, the blood pressure drops to nearly zero. Therefore, when a person is standing, blood returning from the feet is not moved back towards the heart by heart contractions. Because of the changes in blood pressure through the circulatory...
