How does the hypothalamus monitor water in the body?
a. if blood is too concentrated, the hypothalamus nerve cells will contain too much salt.
b. if blood is too concentrated, the hypothalamus it registers dehydration in its own cells.
c. if blood is too concentrated, the hypothalamus registers adh in the blood.
d. if blood is too concentrated, nerve cells in the hypothalamus it has nerve cells that lose water by osmosis and fire more slowly.
e. if blood is too concentrated, in the hypothalamus it registers that its cells are losing water by osmosis.

The correct answer will be option-C.

Explanation:

Hypothalamus is a part of the brain which controls many important functions of the body by producing hormones.

When the amount of water gets reduced in the blood, it leads to a change in the osmolarity which can be easily detected by the osmorecpetors present in the neurons of the hypothalamus.

In response, neurons secrete Anti-diuretic hormone in the blood which acts in the tubules of the kidney where they help in re-absorption of the water from the body.

Thus, Option-C is the correct answer.
