How do the podocytes in Bowman’s capsules perform filtration?
1 answer
The podocytes in Bowman's capsules have specialized foot processes known as pedicels that interdigitate with each other, creating small filtration slits. These filtration slits allow for the passage of small molecules and ions while preventing larger molecules such as proteins from passing through. The podocytes act as a selective barrier, allowing for the filtration of waste products and nutrients from the blood into the renal tubules while retaining important proteins and cells in the bloodstream. This filtration process is essential for the formation of urine and the maintenance of proper blood composition.
