How much of the fluid that comprises filtrate is reabsorbtion into the bloodstream?
Most filtrate is reabsorbed. Remember, just about everything other than cells and large proteins is filtered into Bowman's capusle, and your body needs most of it, or else all you would have running through your blood are cells and proteins. The kidneys reabsorb most of the water, ions and nutrients in the filtrate.
Why is K plus more concentrated in the urine then filtrate?
K+ is more concentrated in the urine than filtrate because while other substances are reabsorbed into the capillaries through the large pores, the potassium mostly stays in the urine, which increases its concentration. Also, the pH of the body needs adjustments, which needs a large amount of K+ to be excreted through the excretory system to adjust to the optimum pH for the body.
What substances does the body need when exercising?
The body mostly needs fats which are used to produce energy. The body also needs water which is used for cooling and other important functions.
Describe how your kidneys remove waste from your body?
The kidney receives blood that it must filter. It has filtering chambers. It separates bad things and converts it to urea. Then it goes through small tubing after it is filtered. The good cleaned blood is sent back to the body and the urea is sent to the bladder.
Why is glucose completely reabsorbed?
The proximal convoluted tubule.The Loop of Henle is the part of the nephron that contains the basic pathway for liquid. The liquid begins at the Bowman's capsule and then flows through the proximal convoluted tubule . It is here that Sodium, water, amino acids, and glucose get reabsorbed. The filtrate then flows down the descending limb and then back up. On the way it passes a major bend called the Loop Of Henle. This is located in the medulla of the kidney. As it approaches the top again, hydrogen ions (waste) flow into the tube and down the collecting duct.

What are some of the substances filtered from the blood by the kidney?
substances that are excreted from the kidneys are urea, uric acid, creatinine, toxins, drugs, plasma inorganic ions,(Na+,K+,Ca2+..ect.) H+, HCO3-, of course H2O, and anything else the body doesn't need that's found in the blood plasma. substances that are reabsorbed are amino acids, proteins, glucose, water, plasma inorganic ions and anything the body needs that is found in the blood plasma. the nephrons are nonselective and secrete everything in the plasma, and the capillaries then reabsorb the vitamins minerals nutrients ect. that the body needs back into the blood, everything the body doesnt need goes to the bladder. What will cause the kidneys to lose more water from the blood? Diuretic hormones
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 substances does the body need when exercising?
The body mostly needs fats which are used to produce energy. The body also needs water which is used for cooling and other important functions.
Which substances are excreted by the kidney?
Nutrients the body needs ( glucose, amino acids, and other small molecules ), electrolytes ( sodium, potassium ), and water are reabsorbed into the blood at the kidney. Sodium, Potassium, and other electrolytes are monitored and reabsorbed as well.
How does the tissue of the kidneys structure to aid in filtration?
Function * Ultrafiltiration: the process by which fluid is filtered out of the blood by the glomerulus. * The blood pressure in a glomerulus causes part of the blood plasma to leak through the capillary walls. The red blood cells and plasma proteins are too big to pass out of the capillary, so the fluid that does filter through is plasma without the protein. The fluid thus consists mainly of water with dissolved salts, glucose, urea and uric acid. * Selective Reabsorption: the process of absorbing back the substances needed by the body. * The filtrate from the glomerulus collects in the renal capsule and trickles down the renal tubule. * As it does so, the capillaries which surround the tubule absorb the substance the body needs back into the blood. * ** The glucose is reabsorbed with much of the water. ** Some of the salts are taken back to keep the correct concentration in the blood. ** *** Salts not needed by the body are left to pass down the kidney tubule with the urea and uric acid. *** They continue down the renal tubule into the pelvis of the kidney, passes down the ureter and to the bladder.

Why re-absorption of water does not occur in collective duct?
Do you mean collection duct? There are several collection ducts. The main function of this part of the kidney is to help keep the ionic balance and water balance. Water is reabsorbed in the first part of this system and the ions in the more distal part. The hormone ADH regulates the amount of water that it reabsorbed. The kidney needs a high blood pressure to function and so it also regulates that.
What are the functions of the liver and the kidneys?
The heart's function is to pump the blood to the rest of the body. The function of kidney is to filter the blood to get rid of waste materials to be disposed of in urine. The function of liver is to store carbohydrates in the form of glycogen and detoxify toxins.
What packages the substances the the cell needs?
Golgi bodies
