At which of the following locations in the nephron would a health care professional first expect blood to be largely free of plasma proteins?
A)
Proximal convoluted tubule
B)
Bowman space
C)
Loop of Henle
D)
Afferent arteriole
Ans:
B
Feedback:
Active filtration occurs when the whole blood enters via the afferent arteriole in to the glomerular capillaries, and the blood is then filtered into the Bowman space, removing plasma proteins. The filtrate that enters the proximal convoluted tubule and the loop of Henle is already free of plasma proteins.
