Verified step by step guidance

Begin by identifying the primary functions of calcium in the human body. Calcium is a vital mineral that plays several roles, including nerve impulse transmission, blood clotting, and muscle contraction.

Understand the role of calcium in nerve impulse transmission. Calcium ions are crucial for the release of neurotransmitters at synapses, facilitating communication between neurons.

Explore the involvement of calcium in blood clotting. Calcium ions are essential in the coagulation cascade, where they help activate various clotting factors necessary for forming a blood clot.

Examine how calcium contributes to muscle contraction. Calcium ions bind to troponin, a regulatory protein in muscle cells, which allows for the interaction between actin and myosin, leading to muscle contraction.

Consider the function of oxygen transport in the body. Oxygen transport is primarily facilitated by hemoglobin in red blood cells, and calcium does not play a direct role in this process. Therefore, oxygen transport is not a function of calcium.
