Cells with large numbers of microvilli on their apical surface are probably involved in?
reabsorption of molecules during production of urine.
Does Antidiuretic hormone inhibits urine production and promote water reabsorption by the kidney?
NO. it increases the permeability of the cells lining the collecting duct via the insertion of Aquaporin 2. This increases the volume of water that is reabsorbed resulting in a concentrated urine. Urine is still produced but not a great amounts.
What prevents the pH of urine from becoming too acidic?
your kidneys buffer it, reabsorption of potassium and sodium
Three steps involved in Urine production are?
Urine functions occurs in the three steps as follows: 1. Filtration : filtrate contains excess water organic and inorganic ions ( Na+, K+, Cl-, creatinine, urea), glucose, ammino acid.in 2. Reabsorption : in PCT, the essential components like glucose, ammino acid and some salts get reabsorption into the renal vein. 3. Tabular Secretion : In DCT, regulation of water in the urine take place with the help of hormone called ADH (Anti-Diurctic Hormone or Vasoptessen) and DCT also release some salt abck to the filtrate to make osmotic conditions.
During a long distance run on a hot day an athlete produces large quantity of sweat As a result the kidney change the rate of urine production Why is this change important?
3. decreases urine production allows the body to converse water
Cells with large numbers of microvilli on their apical surface are probably involved in?

What decreases water loss by increasing reabsorption of water into blood and decreasing urine production?
ADH
Is urine formed when absorption and reabsorption happen during blood filtration?
This is true.
The processes of filtration and reabsorption that occur in the nephron lead to the formation of?
Urine formation in the kidney
What is the function of tubular reabsorption?
Tubular reabsorption is the movement of filtrate from renal tubules back into blood in response to the body's specific needs.
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.
Does Antidiuretic hormone inhibits urine production and promote water reabsorption by the kidney?
NO. it increases the permeability of the cells lining the collecting duct via the insertion of Aquaporin 2. This increases the volume of water that is reabsorbed resulting in a concentrated urine. Urine is still produced but not a great amounts.
What is the major function of kidney during urine production?
water conservation
What is reabsorbtion?
In renal physiology, reabsorption or tubular reabsorption is the process by which the nephron removes water and solutes from the tubular fluid (pre-urine) and returns them to the circulating blood. It is called reabsorption (and not absorption) because these substances have already been absorbed once (particularly in the intestines) and the body is reclaiming them from a postglomerular fluid stream that is on its way to becoming urine (that is, they will soon be lost to the urine unless they are reabsorbed from the tubule into the peritubular capillaries.

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.
What is the main function of the proximal convoluted tubules in urine formation?
reabsorption of most of the required substances from the filtrate
