Atrial natriuretic peptide secreted by the heart has exactly the opposite function of ________ secreted by the zona glomerulosa. a. aldosterone b. epinephrine c. calcitonin d. antidiuretic hormone

Aldosterone is secreted by the Zona glomerulosa of the adrenal cortex of the adrenal gland. It is mineralocorticoid which is a steroid hormone that signals the kidney to prevent sodium ion and water in case of low blood pressure and volume in vessels. To save the water and ion of salts it promotes the reabsorption and leads to low urine output.

On another hand, ANP or atrial natriuretic peptide which release from the heart and enhances the urine output in response to high blood volume and pressure as it ceases the release of the Aldosterone.

Thus, the correct answer is - option A.

An atrial natriuretic peptide secreted by the heart has exactly the opposite function of aldosterone (Option a).

Aldosterone is a steroid hormone secreted by the adrenal cortex of the adrenal gland.

The function of this hormone (aldosterone) is to control the amount of salt (and also water) in the body.

An atrial natriuretic peptide is a molecule that induces the excretion of sodium by the kidneys.

In conclusion, an atrial natriuretic peptide secreted by the heart has exactly the opposite function of aldosterone (Option a).
