THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The process of ultrafiltration occurs in the nephrons of the kidneys. The process can be described as follows: Blood flows through the glomerulus that is surrounded by the Bowman’s capsule. The hydrostatic pressure forces the small molecules to leave the glomerulus and enter in the Bowman’s capsule.

Detailed explanation-2: -Any small molecules such as water, glucose, salt (NaCl), amino acids, and urea pass freely into Bowman’s space, but cells, platelets and large proteins do not.

Detailed explanation-3: -The high hydrostatic pressure forces small molecules in the tubular fluid 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 renal tubules.
