1. constrict arterioles thus increase blood pressure,
2. stimulate ADH secretion from the anterior pituitary which increases water retention by the kidneys and also increases blood pressure, and
3. stimulate aldosterone secretion from the adrenal cortex which increases sodium retention in the kidneys leading to more water retention by the kidneys and helping to increase blood pressure too.
What else can I help you with?
What does angiotensin-converting enzyme do?
Angiotensin-converting enzyme (ACE) is an important enzyme in the renin-angiotensin-aldosterone system (RAAS) that converts angiotensin I to angiotensin II. Angiotensin II is a potent vasoconstrictor that helps regulate blood pressure by narrowing blood vessels. This enzyme is also involved in the regulation of fluid and electrolyte balance in the body.
What does Serum Angiotensin-Converting Enzyme do?
Serum Angiotensin-Converting Enzyme (ACE) is an enzyme involved in regulating blood pressure by converting angiotensin I to angiotensin II, a potent vasoconstrictor. It is also involved in the degradation of bradykinin, a vasodilator. Measurement of serum ACE levels can be used in diagnosing and monitoring certain diseases like sarcoidosis.
What is Angiotensin I?
Angiotensin I is a peptide hormone that is a precursor to Angiotensin II, which plays a role in regulating blood pressure and fluid balance in the body. Angiotensin I is converted to Angiotensin II by the enzyme angiotensin-converting enzyme (ACE).
What are ACE enzymes?
ACE stands for Angiotensin Converting Enzyme. Angiotensin II is the most potent vasoconstrictor in your body. In order to get from Angiotensin I to Angiotensin II, there is an enzyme required for this reaction to occur. ACE inhibitors are used to treat high blood pressure (and congestive heart failure) and they exert their effect by blocking the enzyme.
What is one of the most potent vasoconstrictors released by the endothelium?
Angiotensin II.

Do the kidneys affect angiotensin II?
Certain kidney disorders increase the production of angiotensin II, another cause of hypertension
What triggers the release of aldosterone?
angiotensin
What is Angiotensin I?
Angiotensin I is a peptide hormone that is a precursor to Angiotensin II, which plays a role in regulating blood pressure and fluid balance in the body. Angiotensin I is converted to Angiotensin II by the enzyme angiotensin-converting enzyme (ACE).
What chemical that activates angiotensin II?
Renin
Does Renin cause a decrease in blood pressure?
No. Renin causes the blood pressure to rise. By low blood pressure the body releases Renin from the kidneys. Renin cleaves an inactive peptide, called Angiotensinogen, converting it to Angiotensin I. Angiotensin I is then converted to Angiotensin II by ACE (Angiotensin-Converting-Enzyme). Angiotensin II causes vasoconstriction and thus an increase in blood pressure.
What are the most potent vasoconstrictors known that are peptides?
Urotensin II, Endothelin, Angiotensin II
Production of angiotensin II indirectly?
raises the blood volume
Do angiotensin II blockers affect preload or afterload?
Afterload
What are ACE enzymes?
ACE stands for Angiotensin Converting Enzyme. Angiotensin II is the most potent vasoconstrictor in your body. In order to get from Angiotensin I to Angiotensin II, there is an enzyme required for this reaction to occur. ACE inhibitors are used to treat high blood pressure (and congestive heart failure) and they exert their effect by blocking the enzyme.
What is a hormone that is a potent vasoconstrictor and that stimulates secretion of aldosterone?
Renin which causes the production of Angiotensin which ultimately is converted into Angiotensin II.
