GENERAL HISTOLOGY

Detailed explanation-1: -In renal physiology, ultrafiltration occurs at the barrier between the blood and the filtrate in the glomerular capsule (Bowman’s capsule) in the kidneys.

Detailed explanation-2: -Ultrafiltration occurs in the glomerulus and it is an entirely passive process. This process occurs when the colloidal osmotic pressure plus the capsular pressure remains less than the glomerular hydrostatic pressure..

Detailed explanation-3: -The high hydrostatic pressure forces passes 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. This process is called as ultrafiltration.

Detailed explanation-4: -The kidney has an outer rim (cortex) and an inner core (medulla). Each kidney contains approximately 500, 000 glomeruli, which are small balls of capillaries (diameter 0.1 mm) through which the blood is filtered. Glomeruli are present only in the cortex.
