GENERAL HISTOLOGY

Detailed explanation-1: -Vasopressin acts at the kidney and stimulates resorption of water and electrolytes by the distal tubules and thereby reduces the loss of water through urine (diuresis). It is also called anti-diuretic hormone (ADH).

Detailed explanation-2: -Antidiuretic hormone is made by a part of the brain called the hypothalamus and is secreted into the blood by the pituitary gland. Certain types of tumors may release high amounts of antidiuretic hormone, which can cause low levels of sodium in the blood and the body to retain water.

Detailed explanation-3: -So, the correct answer is ‘Aldosterone and corticotropin’

Detailed explanation-4: -The kidneys are bean-shaped organs that serve several essential regulatory roles in vertebrates. Besides removing urea and uric acid from the blood, the kidneys also help in maintaining the water and salt concentration in it. This process is called as osmoregulation.
