[s8andras]

I must say that your videos are very useful for studies. They are very pedagogcial and the english is in a level which I, as a Swede, don't have problems with understaning.

A great advantage in comparison to a real life lecture, is that you can rewind if you whant to here something again. And I have never had a lecturer whit such great drawing skills.

[1230lilyjune]

[boeing747200lr]

Sal, Thats an awesome sketch!

[mirahp]

WOW, this is fantastic, I am using it for my form 4 class. Thank You. Hope u do not mind

[vickiormindyb]

I've got a major issue about the pulmonary system now.

I just discovered that the cut I was taught to make, in order to get air access for a patient who's not breathing and whose throat is swollen, is not the same as another doctor makes.

The doctor who showed us how to make a cut for cricothyrotomy makes his incision vertically, the other makes HIS horizontally.

I'm telling you. Most doctors can't agree on anything.

[polkadaots]

Great video. Thanks alot!

[jermaine2082]

Thank you so much for your effort and your time. If possible, can you put a video on how the body removes urea and excess ions and how the water content is maintained with the help of red blood cells?

[BF1]

@jermaine2082 He sort of does this with his secondary active transport video since it is about the nephron physiology. But if you need Guyton's medical physiology explains all that in detail if can read that high level of a text.

[billlaAurbillli]

this vid is for kids!!

[aliceyacouba]

woww this is good

[eddik7]

you are great.....very very easy to understand and complete...never boring...thanks...

[tenshady]

Namaste Sal -

5 **** for deploying SUPER DUPER DUPER !!!!

As always Thank you, m Learning quite a bit here without drenching myself in this horrendous sow blizzard.

Ten

[jaakkokuu]

So excited to see this vid. Human physiology is so interesting. I hope Sal's gonna cover the whole system - though it's a huge and complex topic, but so was math or physics =)

5 stars and thumbs up!

[messiahjonz]

I do have a question:

What allows the O2 to be exchanged and not other gases such as nitrogen? As you know the air we breathe is 78% nitrogen and 21% oxygen.

Does it have something to do with the size of the molecules?

Thanks

[furyofnasa]

We breathe out nitrogen too lol

[messiahjonz]

Gee, thanks, but that does nothing to answer my question.

No doubt that nitrogen is expelled.

The question was concerning the exchange of gases.

[messiahjonz]

Great video! I remember most of this from HS, but a year ago I had a pulmonary embolism, which is, as you know, blood clots that block the pulmonary arteries, thus perventing the exchange of oxygen

I had 100's, if not 1000's of clots, and I will be on blood thinners for the remander of my life.

It felt as if I could not breathe, but could get enough air in. Light headed and dizzy, lost weight

1 1/2 foot long blood clot in my leg did it.

Keep aware people

Dr. said I should have died

[95TurboSol]

You rock, Sal, keep em comin :)

[rinwhr]

WOW that's actually pretty good sketch of the guy

Wow Great video. Like your dude there your a very good artist!
