if the water level of the body increases will anti prosterior pitiuitary gland secrete ADH hormone?

Question

Normally a lack of water causes the posterior pituitary gland to secrete antidiuretic hormone. but what will happen if it went up to the level?

Answer 1

it will just decrease or competely stop the release of adh, in fact incerease in blood volume will cause increased filteration at the glomerulus in the nephrons and consequently increase the urine out as there is increased stretching of the urinary bladder. in pathological cases however as in advanced cases of uncompensated heart failure it can cause pulmonary oedema and congestation of the heart and the lungs.

Answer 2

Definitely B. The people answering C, the thyroid gland, are thinking of Thyroxin's effects on the metabolism rates of cells around the body - good, but not directly affecting other glands. The thyroid just determines how much you'll hold onto weight. The pituitary sends out LH and FSH control the reproductive glands, ACTH to stimulate the adrenal cortex, TSH to stimulate the thyroid, ADH for water conservation in the kidneys, growth hormone and even prolactin for women to make breast milk. The pituitary is the master gland - controlling the endocrine system. It is directly connected to the hypothalamus providing a link between the nervous system and the endocrine system.

Answer 3

A large intake of water reduces blood osmolarity, so very little ADH is released. ADH (anti diuretic hormone) primarily affects the distal tubules and collecting ducts of the kidney, where it increases the permeability of the tubule walls to water. Therefore, more water is retained. In a case where there is too much water, less ADH would be released, so more water would be passed through the urine.

Answer 4

It just cuts down on the amount of ADH secreted, so less water is reuptaked in the nephron (at the distal tubule). Eventually you'll just pee out this excess water as it is not being conserved.
