Aldosterone is the primary of several endogenous members of the class of mineralocorticoids in humans. [citation needed] Deoxycorticosterone is another important member of this class. Aldosterone tends to promote Na + and water retention, and lower plasma K + concentration by the following mechanisms:
Hyperaldosteronism (the syndrome caused by elevated aldosterone) is commonly caused by either idiopathic adrenal hyperplasia or by an adrenal adenoma. The two main resulting problems: Hypertension and edema due to excessive Na+ and water retention. Accelerated excretion of potassium ions (K+). With extreme K+ loss there is muscle weakness and ...
Testosterone is converted to 5-DHT by 5alpha-reductase, usually with in the target tissues of 5-DHT because of the need for high concentrations of 5-dht to produce the physiological effects. Aldosterone: mineralocorticoid: adrenal cortex (zona glomerulosa) MR: Increase blood volume by reabsorption of sodium in kidneys (primarily)
Cortisol, corticosterone, aldosterone are produced in the adrenal cortex. [ 25 ] [ 73 ] Estradiol, estrone and progesterone are made primarily in the ovary , estriol in placenta during pregnancy, and testosterone primarily in the testes [ 25 ] [ 76 ] [ 77 ] [ 78 ] (some testosterone may also be produced in the adrenal cortex).
The outermost layer, the zona glomerulosa is the main site for the production of aldosterone, a mineralocorticoid. The synthesis and secretion of aldosterone are mainly regulated by the renin–angiotensin–aldosterone system. The zona glomerulosa cells express a specific enzyme aldosterone synthase (also known as CYP11B2).
In the adrenal cortex, angiotensin II acts to cause the release of aldosterone. Aldosterone acts on the tubules (e.g., the distal convoluted tubules and the cortical collecting ducts) in the kidneys, causing them to reabsorb more sodium and water from the urine. This increases blood volume and, therefore, increases blood pressure.
The food you eat may be affecting your body’s ability to fight cancer cells in the colon, according to a new study. ... due to widely available seed oils often used to fry fast foods and ...
Aldosterone regulates the body's concentration of electrolytes, primarily sodium and potassium, by acting on the distal convoluted tubule of kidney nephrons to: increase sodium reabsorption, increase potassium excretion, increase water reabsorption through osmosis. [1]
