Does anyone know a three letter word which is a hormone that helps lower blood pressure?

Answer 1

Hormones also operate in maintaining the blood pressure. Two hormones of concern are the hormones included in the renin?angiotensin system, and vasopressin. Both are slower regulatory mechanisms of blood pressure.

Renin is an enzyme produced in the juxtaglomerular cells of the kidney. A decrease in the pressure at the renal artery, an activation of the sympathetic nerve fibers to the kidney, or a decrease in the amount of sodium passing through the distal tubule of the kidney, will prompt the release of renin. The release will convert renin to angiotensin I and angiotensin I is converted to angiotensin II in the lung and other organs. Angiotensin II is a potent vasoconstrictor and will also stimulate the release of aldosterone from the adrenal gland. Aldosterone will increase sodium absorption at the kidney, thus allowing for fluid retention and increasing plasma volume (125).

Vasopressin, better known as antidiuretic hormone ,[ADH], is housed in the pituitary gland. Two major stimuli promoting the release of ADH are increase in the plasma osmolarity, and decreases in plasma volume by an indirect route from pressoreceptors in the carotid sinus and aortic arch. These pressoreceptors communicate with the hypothalamus, and a decrease in the firing rate from the receptors will somehow initiate the release of ADH (125). ADH is both a potent vasoconstrictor and plasma volume regulator (107). ADH will regulate plasma volume by resorption of water at the distal tubule of the nephron (125).

ADH is what I think you are referring to.

Answer 2

Calm down! Nothing is going on other than you being freaked out :) All the things you mention are normal "body aches" being put together by you, and mutated into what you fear might be cancer, or aneurysm, or whatever else your health freak complex is creating :) Dont freak out, i was like that for most of my childhood... and man it sucked! Just stay calm, breathe slowwwwwwly and consider it might be something as simple as a migraine, which is easily treated. Stressing out will keep your body running 2x as it should, and if you have low blood pressure, take something salty. IF you are VERY VERY VERY scared, the best you can do is go to the doctor, see if oyu have something, and like i did, walk out with no illness, feeling like a second chance was given to you :) btw, the BP is different from person to person, during different stages of the life, even in different days, depending on waht they ate....
