Quizplus · Accepted Answer

Transportation of oxygen in the bloodstream is not dependent upon the presence of calcium in the body fluids. Calcium is required for blood clotting, muscle contractions, and transmission of nerve impulses. Transportation of oxygen in the bloodstream is not dependent upon the presence of calcium. It is facilitated by iron in the red blood cells, which binds to oxygen and carries it throughout the body. Calcium plays a role in the other processes listed, specifically:
A) blood clotting requires calcium ions to activate the clotting cascade.
B) muscle contractions require calcium ions to bind to certain proteins in muscle fibers, allowing them to contract.
C) transmission of nerve impulses requires the influx of calcium ions into nerve cells to trigger the release of neurotransmitters.
