Question

Define ultra filtration and selective reabsorption. Discuss in brief about the reexcritory function of kidney.

Answer 1

The high hydrostatic pressure forces small molecules such as water, glucose, amino acids, sodium chloride and urea through the filter, from the blood in the glomerular capsule across the basement membrane of the Bowman's capsule and into the nephron. This process is called ultrafiltration


Selective reabsorption The absorption of some of the components of the glomerular filtrate back into the blood as the filtrate flows through the nephrons of the kidney.
