Blood Colloid Osmotic Pressure (BCOP) in the Glomerulus is Generated

Question

Blood colloid osmotic pressure (BCOP) in the glomerulus is generated by
A) blood pressure.
B) presence of albumin proteins in blood plasma.
C) constriction of the efferent arteriole.
D) protein in the filtrate.
E) filtrate in the capsular space.

Accepted Answer

Blood colloid osmotic pressure (BCOP) is primarily generated by the presence of albumin proteins in blood plasma. These proteins are too large to be filtered through the glomerulus and remain in the bloodstream. The presence of albumin creates an osmotic gradient that draws fluid back into the blood vessels from the glomerular filtrate, helping to maintain blood volume and blood pressure.
