Neurohypophyseal secretion of stimulates formation of concentrated urine?
The neurohypophyseal secretion of ADH (antidiuretic hormone) promotes water reabsorption in the kidneys, leading to the formation of concentrated urine. ADH acts on the collecting ducts of the nephrons in the kidneys to increase their permeability to water, allowing the body to conserve water and produce concentrated urine.
Does ADH promote secretion of sodium ions?
No! it doesn't. It just promotes your free water reabsorption in the distal tubules of the kidney. It increases the amount of aquaporines in the cell membrane, causing an influx of water in the medulla of the kidney. Sodium concentration of the urine will be higher because the urine is more concentrated. However, there isn't more sodium excreted.
Diuretics are administered to increase urine secretion?
Yes.
Is ADH inhibited by alcohol or increases urine production or promotes dehydration or is produced in the adenohypophysis?
Alcohol inhibits antidiuretic hormone (ADH) secretion, leading to increased urine production and promoting dehydration. ADH is produced in the hypothalamus and stored in the posterior pituitary gland, not the adenohypophysis (anterior pituitary gland).
What is an antisecretory?
An antisecretory is an agent or drug which decreases gastric secretion.
What is the medical term meaning diminished or lack of urine production or secretion?
Diminished or scant urine production is oliguria. Anuria is absent urine production.
What are the four main physiological processes that contribute to urine formation?
Filtration of blood, re-absorption, secretion of substances, concentration of urine
Agents that promote the secretion of urine are called?
Diuretics promote urine secretion and help to decrease fluid retention. They work by increasing the excretion of water and electrolytes by the kidneys, thus leading to increased urine production. Examples of diuretics include thiazides, loop diuretics, and potassium-sparing diuretics.
What is the mechanism of urine formation?
The mechanism of urine formation takes place by three steps. they are glomerular filtration, tubular reabsorption and tubular secretion.
Are diuretics administerd to increase urine secretion?
Yes, diuretics are medications specifically designed to increase urine secretion. They promote the excretion of water and electrolytes, primarily sodium, from the kidneys, leading to increased urine production. Diuretics are commonly used to manage conditions such as hypertension, heart failure, and edema. By enhancing urine output, they help reduce fluid overload in the body.
What would happen to urine pH if you increased secretion of hydrogen?
it would become more acidic
What are the 3 steps for urine formation?
Filtration As blood courses through the glomeruli, much of its fluid, containing both useful chemicals and dissolved waste materials, soaks out of the blood through the membranes (by osmosis and diffusion) where it is filtered and then flows into the Bowman's capsule. This process is called glomerular filtration Reabsorption by definition, is the movement of substances out of the renal tubules back into the blood capillaries located around the tubules (called the peritubular copillaries). Substances reabsorbed are water, glucose and other nutrients, and sodium (Na+) and other ions Secretion In this respect, secretion is reabsorption in reverse. Whereas reabsorption moves substances out of the tubules and into the blood, secretion moves substances out of the blood and into the tubules where they mix with the water and other wastes and are converted into urine.
