Vinvika [58]

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”.
