What else can I help you with?
What kind of filtered materials are reabsorbed by the blood In the kidneys?
mainly glucose (in the renal tubule) and water (in the collecting duct)
Where does most water reabsorption occur?
Most water reabsorption in the body occurs in the proximal convoluted tubule of the kidney. This is the first part of the nephron where water is reabsorbed back into the bloodstream.
What stays in the tubule after water has been resorbed from blood?
After water has been reabsorbed from the blood in the tubule, waste products such as urea, electrolytes (sodium, potassium, etc.), and other substances like drugs and toxins remain in the tubule to be further processed and eventually excreted as urine.
Where does most absorption take place in the kidney?
the majority occurs in the proximal convoluted tubule
Nephron tube where nutrients are reabsorbed?
The Nephron is the functional unit of the Kidney which regulates blood contents NOT urine contents. It works by filtering out much of the contents of the blood from the Glomerulus into Bowmans Capsule. From here the a long tubule projects and is followed by a blood vessel (the Efferent Capillary) which reabsorbs much of the nutriens, what isn't reabsorbed goes into the Urine via a Collecting Duct. There are three parts to the nephron, the Proximal Convoluted Tubule, the Loop of Henle and the Distal Convoluted Tubule. The loop of Henle is mostly involved in the reabsorbtion of water with the use of salts. The majority of nutrients reabsorbtion takes place is the proximal convoluted tubule. It should be noted that although the nephron is very efficient (it reabsorbs 90% of the water if need be) it also reabsorbs about 50% of the urea so it is incorrect to think that it all goes straight into the urine. In short, to answer you question, most nutrients are reabsorbed in the Proximal Convoluted Tubule.
What is the site that drains the distal convulated tubule in the kidney?
The distal convoluted tubule (DCT) in the kidney drains into the collecting duct. The collecting duct then further conducts the filtrate through the renal medulla, where water and solutes can be reabsorbed. This process ultimately leads to the formation of urine, which is collected in the renal pelvis before being excreted from the body.
What happend in the kidney as the liquid passes though the nephron?
As blood passes into and through the glomerulus, due to the high blood pressure coming into the kidney, water and other solutes, eg: urea, glucose, sodium, potassium and other electrolytes, are forced by pressure thru a membrane and into the nephron. Red Blood cells are too big to pass through this, and remain in the blood vessels, if you do have blood in your urine it can be a indicator of a problem in the kidney. This fluid then moves through the nephrons, the proximal convoluting tubule, the loop of Henle, the distal convoluting tubule and into the collecting duct. On the way, through passive and active osmosis, water, electrolytes are removed from the filtrate and back into the body, until the filtrate is the concentrated formula which then flows out the kidney to the bladder.
Which thing are the constituents of kidney filtrate is reabsorbed by osmosis?
Water
How is the movement of fluid in the kidney?
In the kidney, fluid movement occurs primarily through a series of filtration, reabsorption, and secretion processes within the nephron, the functional unit of the kidney. Blood enters the glomerulus, where filtration occurs, producing a filtrate that contains water, ions, and small molecules. This filtrate then passes through the renal tubule, where essential substances are reabsorbed back into the bloodstream, and waste products are secreted into the tubule for excretion. This intricate process helps regulate fluid balance, electrolyte levels, and waste removal from the body.
How much filtrate is reabsorbed in each part of the nephron?
In the proximal tubule, about 65-70% of the filtrate is reabsorbed, mainly through the process of passive and active transport. In the loop of Henle, about 20% is further reabsorbed, while in the distal tubule and collecting duct, the final 10% of filtrate is reabsorbed, with the amount varying depending on the body's needs for water and electrolyte balance.
In the kidneys the largest volume of water reabsorption occurs in the?
The largest volume of water reabsorption in the kidneys occurs in the proximal convoluted tubule. This is the first segment of the renal tubule where approximately 65-70% of the filtered water is reabsorbed back into the bloodstream.
What are the substances reabsorbed in distal convoluted tubule?
When blood is filtered at the glomerulus (filter unit) of the kidney, some substances don't even make it into the nephron. These include proteins, which are simply too big to diffuse from the capillaries and across the Bowman's capsule. As for what substances are reabsorbed (by active transport) into the bloodstream from the nephron, these include glucose, which is too valuable to be lost in urine. Urea and other substances are lost in the urine.
