Ultrafiltration

What does Ultrafiltration do

It filters small molecules out of the blood into the Bowman's Capsule through podocytes.

What is a podocyte?

'Octopus like' structure, with extended arms. The spaces between the fingers are paths which the filtrate travels through.

What do podocytes do

They prevent large molecules such as proteins and blood cells from passing through. Smaller molecules can pass through due to their high pressure.

What useful substances need to be reabsorbed after ultrafiltration

Amino acids and glucose

What substances are present after glomerular filtration

Water, glucose, amino acids, sodium ions, urea.
