The main role of Vasopressin




Vasopressin, also known as antidiuretic hormone (antidiuretic

hormone, ADH). The posterior pituitary organizations purification of

a hormone. Depending on the hypothalamic neuroendocrine cells of

nuclear synthesis. After synthesis, nerve fiber sheath attached to a

carrier protein, along supraoptic - pituitary axis of the beam and to

the slurry flows downward capillary basement membrane near the

posterior pituitary, stored in the posterior lobe, and often a small

amount released into the bloodstream. Depending on when the nucleus

is stimulated, the impulse along the beam reaches the hypothalamus

pituitary neurohypophysis → large number of vasopressin release. The

main chemical structure of eight amino acid peptide. Two of cysteine

​​as a cystine calculation. Most mammals and arginine vasopressin. Cat

lysine vasopressin vasopressin.

The main role of vasopressin antidiuretic, not to mention high blood

pressure. Hundreds of micro-units can significantly increase the

renal distal convoluted tubule especially collecting duct water

permeability. By increasing the distal convoluted tubule and

collecting duct water permeability tubules and collecting ducts to

promote reabsorption of water, decreased urine output. The effect of

vasopressin increased hypertension need large doses of vascular

smooth muscle contraction can cause a slight increase peripheral

resistance and blood flow.
