Atrial natriuretic peptide has been found to

A) decrease sodium secretion and increase blood pressure.
B) constrict afferent arterioles, decreasing the glomerular filtration rate.
C) be produced by the adrenal cortex.
D) inhibit sodium reabsorption by the collecting ducts.
E) increase the release of renin from the juxtaglomerular apparatus.

Atrial Natriuretic Peptide

A hormone secreted by heart atria cells in response to high blood pressure, functioning to reduce the volume of fluids in the body.

Adrenal Cortex

The outer region of each adrenal gland; secretes steroid hormones, including mineralocorticoids and glucocorticoids.

Sodium Reabsorption

The process by which sodium ions are reabsorbed from the kidney tubules back into the blood, crucial for maintaining body fluid and electrolyte balance.
