What is the main function of the renin?

What is the main function of the renin?

renin, enzyme secreted by the kidney (and also, possibly, by the placenta) that is part of a physiological system that regulates blood pressure. In the blood, renin acts on a protein known as angiotensinogen, resulting in the release of angiotensin I.

What is the function of renin quizlet?

What is the function of Renin? Cells in the kidneys respond to low blood pressure by releasing an enzyme called renin. Renin causes the kidneys to reabsorb sodium. Sodium reabsorption, in turn, is always accompanied by water retention.

Which of the following is the main function of renin and aldosterone?

The main function of renin and aldosterone is to regulate blood pressure and maintain the electrolyte balance. Renin converts angiotensinogen to angiotensin, which stimulates the release of aldosterone from the adrenal cortex. Aldosterone stimulates the reabsorption of Na+ from renal tubules.

Which of the following describes the role of renin in maintaining homeostasis?

The renin–angiotensin system (RAS) is central to the control of blood pressure and fluid–electrolyte homeostasis. Under normal conditions, secretion of renin by juxtaglomerular cells is sufficient to maintain blood pressure and fluid homeostasis.

What stimulates production of renin?

Renin secretion and synthesis are essentially triggered by sympathetic nerve activity with noradrenaline as the main stimulatory transmitter acting via β1 receptors on JGE cells.

Which one of the following is the main function of renin and aldosterone quizlet?

Arteries. Which one of the following is the main function of renin and aldosterone: They are produced whenever blood pressure falls and ultimately cause an increase in blood volume and blood pressure.

Which of the following is a major function of chloride?

Chloride is one of the most important electrolytes in the blood. It helps keep the amount of fluid inside and outside of your cells in balance. It also helps maintain proper blood volume, blood pressure, and pH of your body fluids.

Which one is an important constituent of renin-angiotensin-aldosterone system?

The renin-angiotensin-aldosterone system (RAAS) plays an important role in regulating blood volume and systemic vascular resistance, which together influence cardiac output and arterial pressure. As the name implies, there are three important components to this system: 1) renin, 2) angiotensin, and 3) aldosterone.

How does renin angiotensin work?

Renin catalyzes the conversion of a plasma protein called angiotensinogen into a decapeptide (consisting of 10 amino acids) called angiotensin I. An enzyme in the serum called angiotensin-converting enzyme (ACE) then converts angiotensin I into an octapeptide (consisting of eight amino acids) called angiotensin II.

What is the role of renin in controlling blood pressure?

When blood pressure falls (for systolic, to 100 mm Hg or lower), the kidneys release the enzyme renin into the bloodstream. Renin splits angiotensinogen, a large protein that circulates in the bloodstream, into pieces.

Which of the following describes the role of renin in maintaining homeostasis? Its release is prompted by a decrease in blood volume and blood pressure.
