Which of the choices below are the most important hormone regulators of electrolyte reabsorption and secretion?
The most important hormone regulators of electrolyte reabsorption and secretion are aldosterone and antidiuretic hormone (ADH). Aldosterone acts on the kidneys to increase sodium reabsorption, while ADH acts on the kidneys to increase water reabsorption. Together, these hormones help regulate electrolyte balance in the body.
What is the name of the hormone that promotes sodium retention and potassium secretion?
Aldosterone is the hormone responsible for promoting sodium retention and potassium secretion in the kidneys. It helps regulate blood pressure and electrolyte 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.
What gland is responsible for aldosterone?
The adrenal glands, specifically the adrenal cortex, are responsible for the production of aldosterone. Aldosterone is a steroid hormone that plays a crucial role in regulating blood pressure and electrolyte balance by promoting sodium retention and potassium excretion in the kidneys. Its secretion is primarily stimulated by signals related to blood pressure and electrolyte levels.
Increased secretion of aldosterone would result in a .... blood ph....?
Decreased blood pH. Aldosterone increases sodium reabsorption in the kidneys, leading to increased hydrogen ion secretion as a compensatory mechanism to maintain electrolyte balance. This can result in acidosis, leading to a lower blood pH.
When sodium ions are reabsorbed in response to the action of aldosterone what do potassium ions do?
When sodium ions are reabsorbed in response to aldosterone, potassium ions are often secreted into the urine to maintain electrolyte balance. Aldosterone triggers the reabsorption of sodium in exchange for the secretion of potassium in the distal tubules of the kidney. This mechanism helps to regulate blood pressure and electrolyte balance in the body.
How does dehydration affect aldosterone secretions?
It decreases the affect of aldosterone secretion.
Does excess aldosterone secretion cause dehydration?
Excess aldosterone secretion can lead to dehydration indirectly. Aldosterone promotes the reabsorption of sodium in the kidneys, which in turn increases water retention. However, if there is an excessive loss of potassium and an imbalance in electrolytes, it can disrupt normal fluid balance and potentially lead to dehydration. Additionally, conditions associated with excess aldosterone, such as primary hyperaldosteronism, can result in increased urine output, further contributing to dehydration.
Low blood pressure stimulates the secretion of the mineralcorticoid?
aldosterone
What is the medical term meaning developmental abnormality inherited as a recessive trait that is caused by excessive androgen secretion from the adrenal cortex of the female is called?
congential adrenal hyperplasia
Which hormone plays a central role in determining the rate of sodium reabsorption and potassium secretion?
Aldosterone is the hormone that plays a central role in determining the rate of sodium reabsorption and potassium secretion in the kidneys. Aldosterone acts on the distal convoluted tubules and collecting ducts of the kidney to increase sodium reabsorption and potassium secretion.
What is a hormone that is a potent vasoconstrictor and that stimulates secretion of aldosterone?
Renin which causes the production of Angiotensin which ultimately is converted into Angiotensin II.
