What is not a contribution of the cardiovascular system to other body systems?
Vinvika [58]

OPTIONS:

a) Blood delivers calcium and phosphate ions that are needed for building bone extracellular matrix.

b) Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs.

c) Blood carries newly absorbed nutrients and water to the liver.

d) Blood circulates cells and chemicals that carry out immune functions.

e) Blood delivers clotting factors and WBCs that aid in hemostasis when skin is damaged

Answer:

b) Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs.

Explanation:

Options a, c, d, e are all true statements about the contributions of the cardiovascular system to other body systems except option b which states that “Blood carries carbon dioxide to body tissues and removes oxygen for use by other organs”.  

Actually, the cardiovascular system works together with the respiratory system to supply oxygen to body tissues as blood is circulated in the body, while carbon dioxide is removed from the body at the lungs. <em>In order words, carbon dioxide is removed, while oxygen is picked up as blood is transported through the capillaries of the lungs. </em>
