Question

what is ultrafiltration and re absorption? ?​

Answer 1

Answer:

This process is called ultrafiltration; the resulting fluid, virtually free of large proteins and blood cells, is referred to as glomerular filtrate, or ultrafiltrate. Further modification of ultrafiltrate, by reabsorption and secretion, transforms it into urine.

Answer 2

Explanation:

Ultrafiltration is a passive physical-chemical process whose only selectivity is due to molecule size. ... ... Selective reabsorption occurs because during ultrafiltration, important components of the blood are filtered out and they need to be reabsorbed into the body. ..
