Accepted Answer

Hey, everyone. Let's take a look at this question together which of the following proteins remains in the capillaries and creates an osmotic pressure gradient. Is it answer choice a collagen, answer choice B Albumin, answer choice C fibrinogen or answer choice D Elastin. Let's work this problem out together to try to figure out which of the following answer. Choices is the name for the protein that remains in the capillaries and creates an osmotic pressure gradient. So in order to solve this question, we have to recall what we have learned about each of the following proteins and what it means to remain in the capillaries and create that osmotic pressure gradient, which we know that when we are saying it remains in the capillaries, we are saying that the protein cannot pass through the capillary walls easily. And we know that a protein that is found in the capillaries is albumin, which albumin is a major plasma protein that is too large to easily pass through the capillary walls, which explains how it cannot pass through the capillary walls easily and how it remains in the capillaries and albumin remains in the blood vessels and it contributes to the colloid osmotic pressure and albumin creates a gradient which helps regulate the movement of water between the blood and the surrounding tissues. So, albumin which is a major plasma of protein is too large to easily pass through the capillary walls. So it remains in the capillaries and creates that osmotic pressure gradient. So answer choice B albumin is the correct answer and all other proteins are incorrect. I hope you found this video to be helpful. Thank you and goodbye.
