Under normal conditions, the proximal convoluted tubule reabsorbs all of the glucose, lactate, and amino acids in the filtrate and 65% of the Na+ and water.

Where does selective reabsorption of glucose takes place in the nephron?

Selective reabsorption of glucose occurs in the proximal convoluted tubule of the nephron. Glucose is filtered out of the blood in the glomerulus, and then reabsorbed back into the blood through the walls of the proximal convoluted tubule.


Where does the reabsorption of glucose primarily occur in the kidneys?

The reabsorption of glucose primarily occurs in the proximal convoluted tubule of the nephron in the kidney. Glucose is filtered out of the blood in the glomerulus, and then most of it is reabsorbed back into the bloodstream in the proximal convoluted tubule to prevent its loss in the urine.


What is the last portion of the renal tubule?

the three main portions of the renal tubule are the proximal convoluted tubule, the loop of henle, and the distal convoluted tubule. the proximal convoluted tubule is the first portion. The proximal (convulated) tubule.


What is the primary site of tubular reabsorption in the kidneys?

The distal convoluted tubule or the collecting tube.


Why is there no glucose in urine?

All of the glucose are reabsorbed from the Proximal convoluted tubule into the surrounding capillaries,so there is no no glucose in urine.


Which section of the nephron performs MOST of the glucose and water reabsorption?

proximal convoluted tubule


What happens to glucose if it is not reabsorbed from the proximal convoluted tubule?

If glucose is not reabsorbed from the proximal convoluted tubule, it will continue into the loop of Henle and eventually be excreted in the urine. This condition is known as glucosuria, and it may indicate underlying health issues such as uncontrolled diabetes mellitus.


What are the subdivisons of the renal tubule?

Proximal convoluted tubule, Loop of henle and Distal convoluted tubule.


The portion of the nephron closest to the renal corpuscle is the?

Proximal tubule


What histological feature distinguishes proximal convoluted tubule from a distal convoluted tubule?

Proximal convoluted tubules have brush borders or microvilli on the inner edge of the tubule. Distal convoluted tubules do not have this structure.


What part of the nephron drains into the loop of henle?

The proximal convoluted tubule drains into the loop of Henle.


What is removed at the proximal convoluted tubule?

At the proximal convoluted tubule, reabsorption of water, glucose, amino acids, and ions (such as sodium, potassium, and chloride) from the filtrate back into the bloodstream occurs. Waste products and toxins are also secreted into the tubule for excretion in the urine.
