You have cleared up the fog that has existed for two days!! EXCELLENT!

[HondaSolutions]

Thanks a ton! Good videos! Thanks for sharing your knowledge with others.

[Secretus]

Good video, but there's another aspect to digitialis' effect on the heart that's worth mentioning - namely the fact that sodium accumulation in the cell changes the membrane potential significantly - this causes the NCX to reverse: it starts pumping sodium out, and Ca in, further increasing the strength of contraction.

[mhaas88]

Thanks for the inclusion of drug action! I'm a first year pharmacy student and this was really helpful in my physio course!

[eranbw]

Amazing Skill!! Wish I had you teaching me during my Med school carriar :-) Keep up the great work my friend!!

[triplea309]

Thank you so much for these videos. Your teaching style and drawings are straightforward and incredibly helpful. I cannot thank you enough!

[SinistralMaternalEfc]

I love this guy. I'm going for my phd in genetics, so this type of physiology is not normally my area.

(I had one of only two A's out of fifty students in my last A&P class. So thanks for helping me understand this stuff better.)

[nakeya52]

how does K+ increase in ecf effect the heart?

[jaggysnake3]

Thanks for these videos they are brilliant! One question sorry I'm not quite getting the name of the Ca receptors on the sarcoplasmic reticulum.. any help?

[knot4reel91]

@jaggysnake3 They're the RyR receptor (ryanodine). They're connected to a foot protein which mechanically opens a 'gate' on the sarcoplasmic reticulum, allowing for the eflux of Ca++ into the sarcoplasm.

[BlackGypoMagic]

Your videos scored me a D in my first year uni exam! I love you!

[Muska5]

Thank you sO soO much!! You are amazingggg! =)

[bsms2519]

i am your number fan, you videos are amazing, Well done, you ahve made learning fun for me and well explained. Please do add more videos

[monkeyfizzel]

NCX goes into reverse mode in the presence of high cytosolic Na, thus pumping ca into the myocyte.

[lajames1144]

This is the best!!!!!!!!! Thanks. 

[bboyjojo89]

thank you a lot! from italy!

[almofeed87]

great job.. thanx

[patprathu]

Excellent job, very clear to understand. Thanks a ton

[nuhakadri]

Wow. Thank you so much for taking the time to do this! You're amazing! I actually really understand the whole process and concept instead of simply trying to memorize the terms.

[lbreakzl]

im gonna favor it so hard

[hishoooooooooooooooo]

great video! 

[Haneeno86]

thanx :D

[kardiokonsult]

Thanks a lot, very good explanations, easy to understand! Thank you very much...

[whittvet]

Excellent series! Thanks for doing these videos. They have been a great help for my critical care!

[umar379]

Excellent Job.... !!!

double thumbs up !

[zubery]

use some COLOR!!!!

[mesnagayama]

thanks so much , i love the cardiovascular system except this as i didnt use to understand it, now im rock in it  because of you...god bless so amazing

[nenenede]

This is truely amazing teaching, very clear and understandable demonstrations of complex mechanisms.

[waltzingfrog]

Brilliant stuff I love all your tutorials - gifted teacher! Thanks

[sleepyeyes163]

u are amazing.....my instutor is good but this is the icing on the cake.....i get it now.

thank u

[ELlSSA]

Your amazing!

[vr00m123]

Great job Walid. I want to eventually be in your position during college. I honestly understand everything you've said clearly.

[scroopit]

Thanks for the painstaking efforts.  I appreciate the detail. You're a good man!

[1reem8]

1) Does SA and AV nodes have NCX, membrane bound calcium channel and membrane bound sodium/potassium channels(0:40min---1:00min)?

2) According to action potential graphs of SA node and cardiomyocytes, when does NCX, membrane bound calcium channel and membrane bound sodium/potassium channels is active?

3) When does phospholambin is active?

I hope i am not very confusing or confused...

[heidilanebostick]

amazing, you are a great teacher, you've help me so much!

[gfxmaker]

hey man, thanks! you really helped me out for my test tomo, I couldn't understand my professor nor the book. but thanks to you I think i might actually pull off a good grade!

major thanks, major props!!!

[liaaa90]

now i become a smart girl because of your video, ahaha....

[Sleepless0in0Riyadh]

Thank You sooooooooo much

you really made my day!!!!

[BackFromTheWild]

Thank you so much. I'm in my first year of medical school, and I find my physio professor very confusing. Your teaching style and drawings are very easy to follow. Thank you for taking the time to make the videos and sharing them!

[TheSeanSimpson]

@BackFromTheWild I am where you are now, in exactly the same position you were it seems! :)

[ratrat]

i love your videos!! thanks so much...now i understand~ it helped me heaps!

[lpag119]

jiji, creo que ya le estas pidiendo demasiado conoce del tema sabe explicar, y además pinta! no creo que hable español (triste), pídele ayuda a compañero que sepa ingles, o buscalo en overstream, quizás alguien le ha puesto subtitulos ahí, yo te traduciría algo pero esta como que largito el cuento y no le cojo el acento algunas veces, además no se cuanto confies en mi, si lo deseas dime que parte exactamente no entiendes y yo te lo digo ^^

[mayela777]

thanks so much, you have an incredible way to teach.

you have helped me a lot to understand all these subjects.

[donna777lynn]

walid! im sooooo in love with the way you teach! you married? haha only joking :) but seriously thank you so much...wanna do a cardio pharm series? pleeeeeeease

[mcbukola]
