Question

What effect does the presence of ANP have on the body?
A. It increases the production of renin
B. Increases the excretion of sodium and water
C. It stimulates the production of aldosterone
D. It stimulates the production of angiotensin

Answer 1

Hormones are the chemical messengers in your body. They make their way through your bloodstream to tissues and organs. They have a long-term effect on a variety of processes, including. Development and growth. Metabolism is the process by which your body converts food into energy.

Complete answer:
The NPPA gene encodes atrial natriuretic peptide (ANP) or atrial natriuretic factor (ANF), a natriuretic peptide hormone secreted from the cardiac atria. The natriuretic peptides (ANP, BNP, and CNP) are a group of structurally related hormone or paracrine factors.
ANP's main function is to reduce the volume of expanded extracellular fluid (ECF) by increasing sodium excretion in the kidneys. ANP is produced and secreted by cardiac muscle cells in the walls of the heart's atria. Volume receptors in these cells respond to increased arterial wall stretching caused by increased arterial blood volume.
Secondary effects of ANP's blood volume reduction include decreased extracellular fluid (ECF) volume, improved cardiac ejection fraction with improved organ perfusion, lower blood pressure, and increased serum potassium. Various counter-regulatory mechanisms acting simultaneously on each of these secondary effects may blunt or negate these effects.
The Renin-Angiotensin system raises blood pressure by causing sodium retention and stimulating mineralocorticoid secretion, as stated in the passage. ANP lowers blood pressure by excreting sodium and excess water, as well as causing vasodilation.

As a result, option B is the correct answer.

Note:
The effect of brain natriuretic peptide (BNP), which is secreted by cardiac muscle cells in the heart ventricles, is similar to that of ANP. It works through the same receptors as ANP, but with a 10-fold lower affinity. BNP, on the other hand, has a biological half-life that is twice as long as ANP's, and NT-is proBNP even longer, making these peptides preferable to ANP for certain applications.
