Calcium is needed in the body because it is necessary for ____ Check all that apply.

A	Transmission of nerve impulses
B	Muscle contraction
C	Blood coagulation
D	Cell division
E	Secretion by glands and nerves

Explanation:

Detailed explanation-1: -Blood-borne calcium is also needed for the proper functioning of muscle and nerve cells. When calcium levels in the blood are too low, the parathyroid glands release extra PTH, which leeches calcium from the bones and stimulates calcium reabsorption in the kidney.

Detailed explanation-2: -Your body needs calcium for muscles to move and for nerves to carry messages between your brain and every part of your body. Calcium also helps blood vessels move blood throughout your body and helps release hormones that affect many functions in your body. Vitamin D helps your body absorb calcium.

Detailed explanation-3: -Calcium ions are needed not only for bone mineralization but for tooth health, regulation of the heart rate and strength of contraction, blood coagulation, contraction of smooth and skeletal muscle cells, and regulation of nerve impulse conduction.

Detailed explanation-4: -Parathyroid Gland These are parathyroid glands, and they secrete parathyroid hormone or parathormone. Parathyroid hormone is the most important regulator of blood calcium levels. The hormone is secreted in response to low blood calcium levels, and its effect is to increase those levels.
