EMTs and paramedics may assess the scene to confirm whether the patient is in cardiac arrest and initiate resuscitation. They also transport the patient to the most appropriate definitive care facility—usually the closest hospital that is best equipped to care for a cardiac arrest patient.
Answer:
Aldosterone is the hormone produced by the adrenal cortex, aldosterone is a hormone that inhibits the level of sodium excreted in the urine, maintaining volume and blood pressure.
Explanation:
Several hormonal systems regulate the urinary and intestinal excretion of potassium, so that its activation can produce hypokalemia, and its hyperkalemia blockade.
The most important hormonal axis is the renin angiotensin aldosterone (SRAA) system and the β-adrenergic hormones. In addition to increasing the renal excretion of potassium and the secretion of this cation by the salivary, sweat glands and the intestine, aldosterone can also favor the entry of potassium into the cell.
Aldosterone increases distal sodium reabsorption and potassium secretion. Aldosterone secretion by the adrenal glands is stimulated in hyperkalemia and is inhibited in hypokalemia.
Aldosterone modulates renal excretion of potassium:
- Increasing the intracellular concentration of potassium by stimulating the activity of the Na-K-ATP-Basolateral pump
- Increasing the density and activity of the ENaC channel
- Increasing the expression of ROMK channels
The<u> neurohypophysis </u>releases hormones directly into the blood and the <u>adenohypophysis</u> receives hormones from the hypothalamus cells which in turn causes the release of more hormones.
What are neurohypophysis and adenohypophysis?
The hormones produced by the posterior pituitary are released into the bloodstream directly from the axonal terminals of their source neurons, this region of the pituitary is frequently referred to as neurohypophysis. Two peptide hormones, vasopressin, and oxytocin act as the structural base of a neuro-humoral system that coordinates fluid balance and reproductive function.
The anterior pituitary (or adenohypophysis), controls a number of physiological processes (including stress, growth, reproduction, and lactation). Melanocyte stimulating hormone is produced and secreted by the intermediate lobe.
