What stimulates secretion?
Hypoxia, .e., reduced oxygen tension in blood.
What stimulates the secretion of potassium from the peritubular blood into the distal convoluted tubule?
Aldosterone
What stimulates adh secretion from the posterior pituitary?
ADH secretion is stimulated by factors such as dehydration, high blood osmolality, low blood pressure, and stress. These conditions trigger the hypothalamus to release ADH from the posterior pituitary gland to help regulate water balance in the body.
Excess blood potassium hyperkalemia is removed by increasing secretion of the hormone which stimulates an increase in the secretion of potassium by cells within the?
Excess blood potassium (hyperkalemia) is typically removed by increasing the secretion of aldosterone. Aldosterone stimulates the kidneys to increase the secretion of potassium by cells within the kidney nephrons, promoting the excretion of excessive potassium from the body through urine.
The function of angiotensin II is to?
1. constrict arterioles thus increase blood pressure, 2. stimulate ADH secretion from the anterior pituitary which increases water retention by the kidneys and also increases blood pressure, and 3. stimulate aldosterone secretion from the adrenal cortex which increases sodium retention in the kidneys leading to more water retention by the kidneys and helping to increase blood pressure too.
How do sympathetic and parasymphatetic activity affect gastric secretion?
Sympathetic activity inhibits gastric secretion by causing vasoconstriction of blood vessels in the stomach lining. Parasympathetic activity stimulates gastric secretion by increasing blood flow and activating gastric glands, leading to increased production of stomach acid and digestive enzymes.
When the concentration of sodium in the blood increases what happens to aldosterone and renin secretion and what then results?
High Blood Pressure
How does angiotension 2 affect kidney?
Angiotensin II affects the kidney in various ways: 1) it stimulates the secretion of aldosterone from the adrenal cortex which causes the tubules of the kidneys to increase reabsorption of sodium(Na) and water into the blood increasing the volume of fluid in the body. This can be very useful in cases of hypovolemia(low blood volume). 2) it acts as a vasoconstrictor, thereby increasing test and blood pressure. 3) it stimulates the secretion of anti-diuretic hormone, also called vasopressin which stimulates the reabsorption of water in the kidneys and also acts as a vasoconstrictor. 4)it increases renal hypertrophy in renal tubule cell leading to an increase in Na intake.
Changes in blood osmotic pressure would most affect the secretion of?
Changes in blood osmotic pressure would most affect the secretion of antidiuretic hormone (ADH) by the pituitary gland. ADH helps regulate the concentration of urine by increasing water reabsorption in the kidneys, and its secretion is influenced by blood osmotic pressure to maintain water balance in the body.
The pressure of massage techniques stimulates the release of these hormones to vasodilate the blood vessels?
histamine
Can high blood pressure cause diabetes?
Yes, insulin secretion is affected by high BP.
What is the single most important factor influencing potassium ion secretion?
The single most important factor influencing potassium ion secretion is the potassium concentration in the blood. When blood potassium levels are high, it triggers the release of the hormone aldosterone from the adrenal glands, which in turn stimulates the kidneys to increase potassium secretion to help maintain electrolyte balance.
