Substance that is excreted by the nephron after all of the useful products have been reabsorbed into the blood?

Kidney filters about 180 liters of blood, through nephrons. About 178 liters are reabsorbed. It may surprise you that why kidneys do so much exercise. Reason is that, the waste products of metabolism specially urea and creatinine are very poisonous for brain and body wants to get rid of them at any cost. So urea, creatinine and other waste products of excretion( Like metabolites of drugs and poisonous substances.) are excreted by kidneys.

When a molecule is reabsorbed from the lumen of the nephron where does it go?
The blood vessel that carries blood to the glomerulus is called the afferent vessel. But the glomerulus is not close ended nad the vessel that leaves it, called the efferent vessel, carries on beside the nephron and collects the components that are reabsorbed.
Why does blood contain glucose but normal urine does not?
The glucose along with a lot of other things are reabsorbed in the convolued tubules of the nephron so that it is not waisted by losing it in the urine.
Why do urea and ammonia levels increase after filtration occurs?
Urea and ammonia increase because water is reabsorbed from the nephron, making the urea more concentrated.
What is reabsorbed by the proximal convoluted tubule cells?
Glucose is totally reabsorbed via secondary active transport through co-transport channels driven by the sodium gradient out of the nephron
This is a nephron process that results in a substance in blood entering the already formed filtrate?
secretion
Where is urine excreted in the kidney?
excretion of urine does not occur in kidneys. Urea and wastes and urine are filtered in the renal corpuscle of the nephron tubule in the kidney. The wastes that are secreted into the tubules and not reabsorbed travel down tubules to urethra and excreted outside of body by urination.

Most materials are reabsorbed from nephron tubules into surrounding blood vessels by the process known as?
Selective reabsorption
What happens to glucose which the nephron along with a filtrate?
It is reabsorbed into the blood through blood capillaries surroundings the tubule
What happens to glucose that enters the nephron wit the filtrate?
In most cases it is reabsorbed. It there is too much, it will be "spilled" into the urine.
The process by which the renal tubule actively moves substances from the blood into the nephron to be excreted?
Tubular secretion
Why does blood contain glucose but normal urine does not?
The glucose along with a lot of other things are reabsorbed in the convolued tubules of the nephron so that it is not waisted by losing it in the urine.
What happens to glucose that enters the nephron along with filtrate?
The glucose that enters the nephron along with the filtrate get absorbed by the glomerulus goes to the proximal convoluted tubule (pct) and again reabsorbed and enters the blood.
What will happen if the nephron didn't reabsorb salt and nutrient?
The non-reabsorbed salts and nutrients would exit the Body via the urine.
What substance tells the kidneys to take water from the nephron?
diuretic
Why do urea and ammonia levels increase after filtration occurs?
Urea and ammonia increase because water is reabsorbed from the nephron, making the urea more concentrated.
