  2. Aldosterone - Wikipedia

    en.wikipedia.org/wiki/Aldosterone

    Aldosterone stimulates Na + and water reabsorption from the gut, salivary and sweat glands in exchange for K +. Aldosterone stimulates secretion of H + via the H+/ATPase in the intercalated cells of the cortical collecting tubules; Aldosterone upregulates expression of NCC in the distal convoluted tubule chronically and its activity acutely. [18]

  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. Adrenal gland - Wikipedia

    en.wikipedia.org/wiki/Adrenal_gland

    Sodium retention is also a response of the distal colon and sweat glands to aldosterone receptor stimulation. Angiotensin II and extracellular potassium are the two main regulators of aldosterone production. [19] The amount of sodium present in the body affects the extracellular volume, which in turn influences blood pressure. Therefore, the ...

  5. 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 ...

  6. Mineralocorticoid - Wikipedia

    en.wikipedia.org/wiki/Mineralocorticoid

    Aldosterone and cortisol (a glucosteroid) have similar affinity for the mineralocorticoid receptor; however, glucocorticoids circulate at roughly 100 times the level of mineralocorticoids. An enzyme exists in mineralocorticoid target tissues to prevent overstimulation by glucocorticoids.

  7. Renin–angiotensin system - Wikipedia

    en.wikipedia.org/wiki/Renin–angiotensin_system

    Anatomical diagram of RAS [1] The renin-angiotensin system (RAS), or renin-angiotensin-aldosterone system (RAAS), is a hormone system that regulates blood pressure, fluid, and electrolyte balance, and systemic vascular resistance. [2] [3]

  8. Steroid hormone - Wikipedia

    en.wikipedia.org/wiki/Steroid_hormone

    There are many different mechanisms through which steroid hormones affect their target cells. All of these different pathways can be classified as having either a genomic effect or a non-genomic effect. Genomic pathways are slow and result in altering transcription levels of certain proteins in the cell; non-genomic pathways are much faster.

  9. Endocrine system - Wikipedia

    en.wikipedia.org/wiki/Endocrine_system

    The endocrine system [1] is a messenger system in an organism comprising feedback loops of hormones that are released by internal glands directly into the circulatory system and that target and regulate distant organs.
