Question

What happens in filtration?

Answer 1

Filtration:

1. It is a biological, chemical, or physical process that separates solid particles from a liquid by passing the combination through a filter.
2. The glomerular filtration step of urine generation is an example of the filtration process in the human body.
3. Under pressure, blood enters the kidney, driving filtrate through the glomerulus thin walls into Bowman's capsule.
4. From this filtration water, urea, glucose, acids and various salts come out as filtrate.
5. Almost all of the filtrate produced by glomerular filtration must be reabsorbed by the renal tubules which is known as reabsorption.
6. Waste is secreted from the glomerulus to the renal tubules, then to the renal pelvis, renal calyces, and lastly to the ureters.
