THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -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-2: -Ultrafiltration: Blood enters the glomerulus under pressure because the efferent arteriole is very narrow. Due to that pressure, it undergoes filtration, which is called ultrafiltration. Most of the particles get filtered; that is why it is called ultrafiltration.
