An increase in blood flow to the atria of the heart can cause the release of Atrial Natriuretic Factor (ANF). ANF can cause vasodilation (dilation of blood vessels) and thereby decrease the blood pressure. ANF mechanism therefore, keeps a check on the renin-angiotensin mechanism by acting antagonistic to it.

Assertion : Kidneys maintain the osmotic concentration of the blood. Reason : Kidneys eliminate either hypotonic or hypertonic urine according to the need of the body.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect
Explanation:
Kidneys play an important role in maintaining the concentration and osmotic pressure of the blood. When water intake of an animal is high, the urine excreted has to be hypotonic and lower in osmotic pressure than their blood in order to remove the excess of water. On the contrary when there is a shortage of water, the urine excreted needs to be hypertonic and higher in osmotic pressure than their blood to reduce the loss of water with urine

Vasopressin is also called ____and is synthesized by the ____
1 Atrial diuretic hormone, hypothalamus
2 Antidiuretic hormone, pituitary gland
3 Antidiuretic hormone, hypothalamus
4 Atrial diuretic hormone, pituitary gland
Explanation:
Vasopressin is also called Antidiuretic hormone and is synthesized by the Hypothalamus and is secreted by the pituitary gland.

Which one of the following enables the mammalian kidney to regulate water reabsorption during states of dehydration?
1 The cells of the tubules detect the osmotic pressure of the blood.
2 Water is extracted from the glomerular filtrate in the proximal tubules.
3 The kidney produces a hypotonic urine.
4 ADH increase the permeability of the DCT and collecting ducts to water.
Explanation:
An excessive loss of fluid from the body can activate the osmoreceptors which stimulate the hypothalamus to release antidiuretic hormone \((\mathrm{ADH})\) or vasopressin from the neurohypophysis. \(\mathrm{ADH}\) facilitates water reabsorption from latter parts of the tubule i.e. DCT and CT, thereby preventing diuresis.
