Aldosterone synthesis is regulated by angiotensin II and potassium. WebAldosterone secretion from the zona glomerulosa of the adrenal cortex is stimulated by a range of secretagogues, of which A-II is the most potent, although potassium and adrenocorticotropic hormone (ACTH) (which augment aldosterone production) and the cardiac natriuretic peptides (which are inhibitory) may be important in heart failure. 116 … st zachary church

WebSummary. Adrenal gland histology is the study of the microscopic structures of tissues of the adrenal gland. The adrenal gland is a small, triangular-shaped organ that sits on top of each kidney. It has two parts: the cortex and the medulla. The cortex is made up of three layers: the zona glomerulosa, the zona fasciculata, and the zona reticularis. http://medcell.org/histology/endocrine_systems_lab/zona_glomerulosa.php
