ANATOMY

Detailed explanation-1: -Aldosterone (ALD) is a hormone your adrenal glands release that helps regulate blood pressure by managing the levels of sodium and potassium in your blood. Sodium and potassium are electrolytes.

Detailed explanation-2: -Aldosterone is a steroid hormone secreted by adrenal glands. Its main role is to regulate salt and water in the body, thus having an effect on blood pressure.

Detailed explanation-3: -Aldosterone stimulates reabsorption of sodium by the distal tubule of the nephron and a concomitant excretion of potassium, magnesium, and protons into the urine. Sodium reabsorption into the blood is also stimulated at three other sites where the ion may be excreted: the sweat glands, salivary glands, and colon.

Detailed explanation-4: -Aldosterone is secreted by the adrenal cortex and promotes sodium reabsorption by the kidneys. As sodium is reabsorbed back into the blood, water is reabsorbed also. Antidiuretic hormone is produced by the hypothalamus and released from the posterior lobe of the pituitary gland.

Detailed explanation-5: -ADH directly increases the tubules’ reabsorption of water by opening pores in the epithelial cells of the kidneys, whereas aldosterone indirectly increases the water reabsorption of the tubules by creating an osmotic pressure through increasing the activity of sodium pumps.
