In the glomerular capillary (GC), fluid moves into Bowman’s capsule through its almost entire length. But in the muscle capillary (MC), fluid moves into interstitial space at its arteriolar end. […]

The difference in circulation between glomerular capillaries (GC) and true capillaries (TC) are described by a researcher in the following statements: A. The hydrostatic pressure in GC is higher than […]

In a healthy kidney given the following information: (A) Glomerular hydrostatic pressure — 75 mm Hg (B) Glomerular capillary colloid osmotic pressure — 40 mm Hg (C) Hydrostatic pressure in […]

Three forms of dextrans namely neutral, polyanionic and polycationic having different molecular radii were injected separately in three groups of rats. The concentrations of dextrans in glomerular filtrate were measured […]

During urine formation the filtration of blood at the glomerulus is (1) an active process. (2) an osmotic process. (3) is a pressure-dependent physical process. (4) a non energy- mediated […]

Which one of the following is not present in the filtration slit diaphragm? (1) NEPH1 (2) Paxillin (3) Nephrin (4) NEPH2 The filtration slit diaphragm in the kidney glomerulus is […]

Filtration slits are formed by (1) podocytes (2) endothelial cells of capillary (3) mesangial cells (4) Lacis cells Filtration slits are crucial microscopic structures in the kidney’s filtration barrier, playing […]

Desert rattlesnakes live in extremely dry environment. In order to conserve body water, they are adopted to convert ammonia to (1) urea. (2) purines. (3) uric acid (4) amino acids. […]

On investigating the excretory organs of an organism that was found in an office backyard, the following structures were identified. A funnel-like structure to collect the waste, duct-like structures to […]
