Explain the important differences between blood plasma and glomerular filtrate, and relate the differences to the structure of the filtration membrane.

Video transcript

Hello everyone and welcome to today's video. So which of the following is or are not present in the glomerular filtrate. As answer choice A we have blood cells, B plasma proteins, C amino acids D both A and be both B and C. But in order to solve this problem, we need to understand what's going to be found in this glome or filtrate. What we know from previous videos are molecules smaller then three nanometers in diameter such as water glucose amino acids. A nitrogenous was is are small enough to enter this filtrate and therefore they're going to be found in it. Anything else is probably going to be barred from entering this filtrate? Now, for example, larger molecules or molecules are larger, then five nanometers in diameter won't be able to enter the filtrate. For example, we have plasma proteins and certain blood cells because these proteins and these cells are larger than five nanometers that won't be able to enter the filtrate. So they will not be present on it. Looking at our answer choices. Blood cells is answer choice. A plasma proteins is answer choice B these two are correct. Now, amino acids, we said that they are small enough in, in order to enter the filtrate. So we're going to cancel them out because they're going to be present in it. Therefore, answer choices A and B are correct and we can highlight answer choice. D both am B as a final answer to our question, I really hope this video helped you and I hope to see you on the next one.
