  2. Aldosterone - Wikipedia

    en.wikipedia.org/wiki/Aldosterone

    Aldosterone is the main mineralocorticoid steroid hormone produced by the zona glomerulosa of the adrenal cortex in the adrenal gland. [ 4 ] [ 5 ] It is essential for sodium conservation in the kidney, salivary glands, sweat glands, and colon. [ 6 ]

  3. Adrenal cortex - Wikipedia

    en.wikipedia.org/wiki/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).

  4. Zona glomerulosa - Wikipedia

    en.wikipedia.org/wiki/Zona_glomerulosa

    The enzyme aldosterone synthase (also known as CYP11B2) acts in this location [3] [4] The expression of neuron-specific proteins in the zona glomerulosa cells of human adrenocortical tissues has been predicted and reported by several authors [5] [6] [7] and it was suggested that the expression of proteins like the neuronal cell adhesion ...

  5. Mineralocorticoid - Wikipedia

    en.wikipedia.org/wiki/Mineralocorticoid

    Aldosterone acts on the kidneys to provide active reabsorption of sodium and an associated passive reabsorption of water, as well as the active secretion of potassium in the principal cells of the cortical collecting tubule and active secretion of protons via proton ATPases in the lumenal membrane of the intercalated cells of the collecting tubule.

  6. Adrenal gland - Wikipedia

    en.wikipedia.org/wiki/Adrenal_gland

    The production of steroid hormones is called steroidogenesis, and involves a number of reactions and processes that take place in cortical cells. [5] The medulla produces the catecholamines, which function to produce a rapid response throughout the body in stress situations. [4] A number of endocrine diseases involve dysfunctions of the adrenal ...

  7. Renin–angiotensin system - Wikipedia

    en.wikipedia.org/wiki/Renin–angiotensin_system

    Angiotensin II is the major bioactive product of the renin–angiotensin system, binding to receptors on intraglomerular mesangial cells, causing these cells to contract along with the blood vessels surrounding them; and to receptors on the zona glomerulosa cells, causing the release of aldosterone from the zona glomerulosa in the adrenal cortex.

  8. Collecting duct system - Wikipedia

    en.wikipedia.org/wiki/Collecting_duct_system

    The epithelium is composed primarily of principal cells and α-intercalated cells. [7] The simple columnar epithelium of the collecting duct system transitions into urothelium near the junction of a papillary duct and a minor calyx. [6] These cells work in tandem to reabsorb water, sodium, and urea and secrete acid and potassium.

  9. List of human hormones - Wikipedia

    en.wikipedia.org/wiki/List_of_human_hormones

    The following is a list of hormones found in Homo sapiens.Spelling is not uniform for many hormones. For example, current North American and international usage uses [citation needed] estrogen and gonadotropin, while British usage retains the Greek digraph in oestrogen and favours the earlier spelling gonadotrophin.
