kidney: osmolarity of filtrate in bowmans capsule

I am going over how the osmolairty changes though the kidney....

But I am just wondering: How does the omolarity of the initial filtrate in bowman's capsule compare with the initial blood in afferent arteriole?


I was thinking it could be LESS, because the blood proteins do not go though the filter (eg albumin). But that's assuming that water goes though very easily

Any thoughts?

I racked my brain through this question and I do not see why you would be incorrect in your thought process. I considered high and low BP and there may be slight changes but only 20% of the blood's protein (amino acids) is filtered. There should be less osmolarity in the filtrate vs. the initial blood considering water, common ions and glucose, amino acids are the only material filtered... Correct me if I am wrong

cool thanks...sorry to make you "rack your brain" 😀
