2021 and these lessons are helping me for my a&p class! this professor is awesome!

@BabyloveAsian Semi-permeable isn't pertaining to molecules but to the membrane itself. When we say semi-permeable we're saying that the cell membrane is only allowing certain substances through and not others. There are a handful of factors that affect permeability such as the charge of the substance trying to pass through, the gates that are found in the membrane and so on.

@rajji28 You are welcome, I'm glad this helped

Your College Prof would have been proud. You have a gift in teaching. It really makes all the difference in the world where before I would try to memorize the material like a robot, and now I realize how important it is to actually UNDERSTAND it - - This is the key to embedding the material into memory! So thank you so much! Your video presentations are good for my health LOL

I just found this. Im taking an online class and I pretty much have to teach myself. There is no instructor to explain the text. This video made it all come together for me, THANK YOU SO MUCH!!

Great video but the thing with the equilibrium is incorrect, the molecules are not stationary at a equilibrium, they are actually entering the cell and leaving the cell at a same rate. For example when our blood cells are at a equilibrium state, H2O is leaving and entering at the same rate.

After taking anatomy 3 times and making Ds yours videos got me my first B and I want to say thank you and keep doing what your doing because you are helping out a lot of students where professors drag their feet

[@inhabitantofearth]

how does nonpolar substances get through the polar heads if nonpolar substance are hydrophobic? is it because the membrane is mostly nonpolar, so the force of attraction is strong enough to get it through?

[@rajji28]

really helpful ...thanks for uploading.

@Yasminesantos17 You are very welcome, I'm glad this helped.

[@BabyloveAsian]

So when somebody says that a certain substance has a semi permeable membrane. What does that mean?

[@kilgoretrout3419]

Bullharrier, do you have practice quizzes for this course anywhere?

[@Ejay0501]

This is a great help for my exam.. Thank you so much!! i will recommend this to my friends..

[@altforfit]

You make anatomy and especially physiology delightful to learn about

[@bullharrier]

@bomberfun1 You are very welcome, I'm glad i could help

[@bullharrier]

@udaysexy Tap water is fine, even if you filter tap water it's alright. Just pure distilled water in high amounts isn't the best idea in the world for the reasons explained in the video.

[@YasmineSantos17]
