Aldosterone MCQs
Hello Students, Today’s topic is Aldosterone. Aldosterone is a steroid hormone which is synthesized by the Zona glomerulosa of the adrenal cortex. Adrenal cortex is a portion in an adrenal glands as we studied before. Aldosterone is also responsible for the fluid balance in the body. Aldosterone is also known as Mineralocorticoids hormone.
