A) Is hypoosmotic due to glomerular filtration

E) Has a lower oncotic pressure than afferent ateriolar blood

Question

Quizplus · Accepted Answer

The efferent arterioles carry blood away from the glomeruli. After filtration occurs in the glomerulus, the remaining blood has a higher concentration of proteins since smaller molecules and water are filtered out. This increases the oncotic pressure in the blood within the efferent arterioles compared to systemic blood.
