How does the reabsorption of sodium and water from the renal tubules increase blood volume?
When blood volume is low, sodium reabsorption in the kidneys is stimulated. The increased sodium increases osmotic pressure, causing water to be reabsorbed with the sodium. The reabsorbed water is added to the plasma, thus increasing blood volume.
What are the three steps of urine formation and in what part of the nephron does each occur?
Urine formation and the adjustment of blood composition involve three major processes: glomerular filtration by the glomeruli, and tubular reabsorption and tubular secretion in the renal tubules. In addition, the collecting ducts work in concert with the nephrons to concentrate or dilute the urine..Functions of the nephrons include filtration, tubular reabsorption, and tubular secretion. Via these functional processes, the kidneys regulate the volume, composition, and pH of the blood, and eliminate nitrogenous metabolic wastes.
How does the kidney respond low blood volume?
kidneys will secrete a hormone called erythropoietin
Which vessel does blood flow the fastest?
VEINS have largest volume of blood because they are more compliant than artries .
What is urinary system and its function?
The urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys filter the blood to remove wastes and produce urine. The ureters, urinary bladder, and urethra together form the urinary tract, which acts as a Plumbing system to drain urine from the kidneys, store it, and then release it during urination. Besides filtering and eliminating wastes from the body, the urinary system also maintains the homeostasis of water, ions, pH, blood pressure, calcium and red blood cells.The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH. The kidneys have an extensive blood supply via the renal arteries which leave the kidneys via the renal vein.

When blood volume is low, sodium reabsorption in the kidneys is stimulated. The increased sodium increases osmotic pressure, causing water to be reabsorbed with the sodium. The reabsorbed water is added to the plasma, thus increasing blood volume.

The main region of aldosterone action is the?
The main region of aldosterone action is the distal convoluted tubule (DCT) and collecting duct of the kidneys. It functions to increase sodium reabsorption as well as enhance potassium excretion. The net effect of this is an increase in blood volume (via increased reabsorption of water), and thus an increase in blood pressure.
Explain how antidiuretic hormone can help regulate hypotension Be specific?
it can help by increasing reabsorption of water by the kidney. With the reabsorption, blood plasma volume increases, thus raising 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.
What does aldostrone cause?
Aldosterone is a hormone that increases the reabsorption of sodium ions and water and the release (secretion) of potassium ions in the distal convoluted tubules of the kidneys. This increases blood volume and, therefore, increases blood pressure. Drugs that interfere with the secretion or action of aldosterone are in use as antihypertensives.
Which planet has the largest volume?
Jupiter is the largest planet. It has the largest volume, largest diameter, and largest mass.
What organ removes waste from the blood and control blood volume?
kidneys
What is the meaning of vasopressin?
vasopressin is an antidiuretic hormone responsible for increased permeability of the distal tubules of the kidney, increasing water reabsorption and reducing urine volume.
What is the largest freshwater lake by volume?
The largest freshwater lake by volume is Lake Baikal in Russia.
How do diuretics work?
It reduces the blood volume through greater excretion of water by the kidneys.
The kidneys are responsible for the production of what to maintain normal red blood cell volume?
erythropoietin.
