What is the sequence of blood vessels supplying the kidney?

Please select an option Incorrect. Each kidney is supplied by a renal artery, a branch of the abdominal aorta. The renal artery divides into several interlobar arteries.

The role of the juxtaglomerular apparatus in the kidney is to synthesise and secrete which enzyme?

Why is the oncotic pressure in the Bowman's space normally zero?

Please select an option Correct! Most proteins are too large to be filtered and therefore remain in the glomerular capillary. Large proteins are not filtered into Bowman's capsule unless a component of the filtration barrier (e.g. the glomerular basement membrane) is damaged. WikiVet Article: glomerular filtration. Incorrect. Most proteins are too large to be filtered and therefore remain in the glomerular capillary. Large proteins are not filtered into Bowman's capsule unless a component of the filtration barrier (e.g. the glomerular basement membrane) is damaged in which case the oncotic pressure would be higher than zero. Oncotic pressure in the Bowman's capsule is normally zero because filtered fluid is essentially protein free. WikiVet Article: glomerular filtration. Incorrect. Large amounts of protein are not capable of being reabsorbed from the nephron back into the blood. Most proteins are too large to be filtered and therefore remain in the glomerular capillary. Large proteins are not filtered into Bowman's capsule unless a component of the filtration barrier (e.g. the glomerular basement membrane) is damaged. Oncotic pressure in the Bowman's capsule is normally zero because filtered fluid is essentially protein free. WikiVet Article: glomerular filtration. Incorrect. Hydrostatic pressure does not directly affect oncotic pressure. Most proteins are too large to be filtered and therefore remain in the glomerular capillary. Large proteins are not filtered into Bowman's capsule unless a component of the filtration barrier (e.g. the glomerular basement membrane) is damaged. Oncotic pressure in the Bowman's capsule is normally zero because filtered fluid is essentially protein free. WikiVet Article: glomerular filtration. Incorrect.
