Glomerular Filtrate is Chemically Most Similar to ________

Question

Glomerular filtrate is chemically most similar to ________.
A)Urine
B)Plasma
C)Lymph
D)Cytoplasm

Accepted Answer

Glomerular filtrate is formed by the filtration of plasma through the glomerulus in the kidneys. As a result, the chemical composition of glomerular filtrate is very similar to that of plasma, with the exception of larger molecules like proteins which are not filtered through the glomerulus. Urine is formed by the process of reabsorption and secretion in the kidneys, which alters the composition of the filtrate. Lymph and cytoplasm are not relevant to the composition of glomerular filtrate.
