Current Question (ID: 14469)

Question:
What does systemic circulation provide to tissue?
Options:
  • 1. nutrient
  • 2. oxygen
  • 3. other essential substances
  • 4. all of these
Solution:
Systemic circulation provides all of these: nutrients, oxygen, and other essential substances to tissues throughout the body. The oxygenated blood is pumped out from the left ventricle of the heart into the aorta, which then branches into smaller arteries and arterioles, carrying oxygen and nutrients to the capillaries that supply the tissues. In the capillaries, exchange of gases and other substances occurs, and the deoxygenated blood is then collected in venules and veins to be returned to the heart via the superior and inferior vena cava for re-oxygenation.
