Explain the Factors That Affect the Reabsorption Process

There are also two major factors that affect the reabsorption process.

These include:

1) Concentration of small molecules in the filtrate - the higher the concentration, the more molecules can be reabsorbed.

2) Rate of flow of the filtrate- the flow rate affects the time available for the transporters to reabsorb molecules. The useful products return to the blood and the water is passively reabsorbed. Sodium and chloride ions are actively reabsorbed, which encourages the water to follow. Amino acids and glucose are reabsorbed to blood. The reabsorption rate is 400 mg/100ml plasma. The rest of the glucose is in the urine. In diabetes mellitus, the excess glucose is present in the blood. A part in the filtrate is reabsorbed, part is not.
