Définition et Signification de "aldosterone"

What is "aldosterone"?

Aldosterone is a hormone produced by the adrenal glands as part of the endocrine system. It belongs to a group of hormones called mineralocorticoids and is primarily involved in regulating electrolyte balance, particularly the reabsorption of sodium and excretion of potassium in the kidneys. Aldosterone acts on the distal tubules of the nephrons, promoting sodium retention and potassium excretion, which helps maintain blood pressure, blood volume, and overall fluid balance. Its secretion is regulated by the renin-angiotensin-aldosterone system and influenced by factors such as blood volume, sodium levels, and the presence of certain hormones. Overall, aldosterone plays a crucial role in maintaining electrolyte homeostasis and blood pressure regulation in the body.
