converting enzyme (ACE) inhibitor - a medication that lowers blood pressure. ankle sprain - overstretched lateral (outside) ligament of the ankle joint. anosmia - absence of the sense of smell.
either of two forms of a protein associated with regulation of blood pressure; angiotensin I, produced by action of renin on angiotensinogen, is converted by a plasma enzyme into angiotensin II which releases aldosterone
(an´ jee oh ten´ sin) • A peptide hormone that raises blood pressure by causing peripheral vessels to constrict; maintains glomerular filtration by constricting efferent glomerular vessels; stimulates thirst; and stimulates the release of aldosterone.
This compound activates production of aldosterone. Production of angiotensin is controlled by RENIN.
A neuroactive hormone involved in the regulation of blood osmolarity and water balance, and in drinking behavior.
A substance produced by the kidneys when there is a decrease in the amount of liquid passing through them, activating receptors in the brain that monitor the volume of blood and other fluids in the body.
any of several vasoconstrictor substances (trade name Hypertensin) that cause narrowing of blood vessels
A substance in the blood that causes blood vessels to tighten, raising blood pressure.
A chemical the body produces that causes the arterioles to constrict.
A substance formed in tissues or blood vessels when there needs to be local or even massive vasoconstriction. The primary precursor is renin, made by the kidneys, and elevated when the blood seems dehydrated or low in volume; the next substance needed for this reaction is a liver protein, angiotensinogen; when both are present in the blood, local factors can then form this pressor substance. Excess production is often implicated in high blood pressure.
Part of the blood pressure regulating system within the body. This goes awry with Polycystic Kidney Disease, causing elevations in blood pressure.
converting enzyme (ACE): enzyme that causes inactive angiotensin I to be converted to active angiotensin II
A family of peptides (smaller than proteins) that act as vasoconstrictors to narrow blood vessels.
converting enzyme (ACE) inhibitor - A drug that lowers blood pressure by blocking the formation of angiotensin, a substance that constricts arteries.
A vessel-constricting substance present in the blood, and formed by the action of renin (enzyme involved in changing proteins into other products) on a globulin (a class of proteins characterized by being insoluble in water, but soluble in saline solutions ) .
A protein that increases blood pressure by constricting blood vessels and stimulating the release of aldosterone. The inactive form is angiotensin I, and the active form is angiotensin II (see Hypertension).
A blood chemical that constricts blood vessels, thereby raising blood pressure.
II Hormone formed by action of angiotensin converting enzyme on angiotensin I: stimulates aldosterone secretion from adrenal cortex, vascular smooth-muscle contraction, and thirst.
Angiotensin is an oligopeptide in the blood that causes vasoconstriction, increased blood pressure, and release of aldosterone from the adrenal cortex. It is a powerful dipsogen. It is derived from the precursor molecule angiotensinogen, a serum globulin produced in the liver.
