Just 1 correction at 5:45 you said Glucose as wel as Fructose are passively transported. You are true about Fructose but not for Glucose ,this is Secondary Active transport here Sodium Glucose cotransport through GLUT1 The video is absolutely amazing though and thank you for sharing your knowledge with us and keep on uploading the videos .

Hi, thank you for this awesome video. I was wondering why the cells intracellular compartment are not rich in Na+, if Na+ has to pass through them first in order to reach the plasma. I would believe that it is because of electrochemical gradient, however, if the electrolytes reach a point of saturation, I would also think that they will not be absorbed, and they will be lost in defecation. Thus, how does the Extracellular compartment end up having more Na+ since sodium cannot cross plasma membrane easily? Is it because the sodium, once inside of the cell at a certain concentration, will be brought in the ECF readily to have an equilibrium and also to allow more Na+ to get in? I hope you understand my question, if not I can always think of a way to clarify it. Thank you very much.
