video description

Rating: 4.0; Vote: 1
Hank describes how cells regulate their contents and communicate with one another via mechanisms within the cell membrane calorion: Ok, I-m confused. at 4: 00, the red blood cell is hypertonic, and so the solutions inside the cell want to equalize their concentrations-pure water rushes -in- and the cell explodes? Wouldn-t it be the other way around, and the cell explodes because everything inside is trying to get -out- all at once?

I was diagnosed with posterior urethral valves at 15 and I'm 33 now. This condition is characterizes as obstructing membranous folds within the lumen of the posterior urethral, can this condition be remedied somehow?

I have a question. Sodium being absorbed in the kidney or water moving out of the small intestine, are any of these a form of active transport? I-d like to believe the latter is an active transport but I-m not sure.

I just want to say thank you so much for this video. I was studying osmolarity and tonicity for hours and just not getting it. Then, after watching just half of this video everything clicked. Thank you!

Wait.
Is the water going in to the salt water stick thing and pushing out the salt water with higher concentration or is the salt water that goes out by itself?

8: 47 I am confused. He says that the pump brings all of the sodium ions in, but I thought that the pump pushes sodium out and potassium in
