Quizplus · Accepted Answer

Glomerular filtrate is a fluid that is filtered from the blood plasma in the glomerulus of the kidneys. It contains many of the same substances as plasma, such as water, electrolytes, and small molecules like glucose and amino acids. However, it does not contain larger molecules like proteins because they cannot pass through the filtration membrane. Therefore, option B is the correct answer as it states that glomerular filtrate includes the same substances as plasma except for larger protein molecules.
