The structure that he labeled as pericardium is actually only a part of it, called the serous pericardium. There is one more layer of dense connective tissue on the outside, called the fibrous pericardium that has been omitted. Please upvote and/or comment to this so that others can see it.

Yes, also known as epicardium. Which would be more helpful to label since epi means outer most.

This video is so much clearer than the lecture given by the professors at my university. They try to sound overly formal, which only gets in the way of what they're trying to communicate. Thank you so much!

Thank u..! But there is two type of pericardium they are 1_fibrous pericardium (which contain strong fibrous ) and the second one is a 2_serous pericardium (the inner portion of pericardium which composed two layers A_visceral layer (which contact with myocardium ) B_parietal layer (which contact with fibrous pericardium ).

Yes, they are the same thing. Mitral valve = Bicuspid valve.

I just hit a gold mine finding your channel. You will help me conquer my human anatomy course. Thank you!

You are a LIFE SAVER! I have the worst A&P II professor in the entire world. You explain so clearly. Where have you been all my life?

I am a Spaniard going to school in Germany to become a nurse and you have no idea how much your videos are helping me. I get so lost in translation while in class sometimes... THANK YOU!

Great question. This can result in a valve that doesn't work properly and flops back and forth instead of providing a good seal. Blood can go the wrong way in this situation and lead to less efficient pumping of blood to the body.

U r the best thing that happened to my life thanks

i can not say it enough! your channel has changed my life! you helped conquer physiology and now my anatomy class!

Love this guy! He makes A & P so much easier! I've learned so much from him while I work on my nursing degree. Thank you Khan guy (with the deep voice)!

Thank you for doing these videos. They help me in better understanding the heart.

Good way of teaching..I understand better now...

Nope, the mitral valves are between the atria and ventricles. The semilunar valves (there are two) separate the right ventricle and pulmonary artery, and the left ventricle and aorta. Hope this helps

I'm watching all of your video for my RCIS exam in two weeks. You have the best video on KZread!

thank you i really really thank you from the deep of my heart .... you do know how much this vedio help me out...... we really appreciate what you are doing....

wow I am a nursing student and I am enjoying all these videos!!! Amazing learning tool!

Thankkk youuu. Soo the sac around heart is actually part of heart layers !!! Omg I have been thinking whole time that that sac is around the whole heart and heart enclosed in between....

Woooa..... Thank u . But i was hoping a little bit advanced explanation

Thank you best explanation EVER !!!!!!!

KHAn academy for the WIN!

Aw man this makes so much more sense now! Thank you!

Thank you so much khan academy..u are the best

this week all am doing is watching all your 10 circulatory system videos, u re that good

DO YOU OFFER A SUMMARY OF WHAT IS SAID IN THE VIDEO? THAT WOULD be great. please

Thank you so much! I am a paramedic student and was wondering if you have a video on simplifying EKG's. You are a great teacher and really thank you for taking your time to post these!

This all makes sense to me now. Thank you!

Thank you!

Just had my herbalife liftoff energy drink and I'm not sleepy, I just remembered my favorite subscription to keep me busy😊thank you, your videos are the best👌

Hello, I noticed at time (7:16-7:20), right after you finished talking about the endocardium layer, you mentioned that you go deeper into the myocardium. I think that was a mistake. From superficial to deep, the tissues should go as follows: Pericardium, Myocardium, and Endocardium. Therefore, myocardium is NOT deeper than endocardium; it is more superficial.

Thank you so much for this video. You explained the layers of the heart and the intraventicular septum better than my teacher. Thanks

Thank u 🌸👍

Thank You, Rishi.

Khan Academy RULES!

Thank you thank you thank you.!!!!!!!... great video!

Nursing Student...question... Cardiac Tamponade...does the blood fill in the gap of the Perimetrium? Thx Khan...I used your videos for Chemistry 101 also.

woooah sal i pretty watch this video forever in this life

perfect explaination

I like this video. Great presentation.

really good at explaining !thanks !

i need to learn this so thank you

very helpfull! thank you

This is a great explanation! Greetings from Mexico, man!

Standing ovation!

Great explanation,, Thank You

You're amazing at explaining

I won't forget that there is a little bit of fluid.

hi could you please make a lecture on arrhythmias and the different types

And in that gap, you might have *A LITTLE BIT OF FLUID* but its not actually cells.

life saver

heads up, at 8:53 it gets suddenly louder for a second

Hi thanks for your videos they re so useful :) ..I have a question is the mitral valve,the sae as the bicuspid valve if not what does that do? thanks

thanks for this it helped

well done, thank you!! :)

My bad. Still, they're not called the semilunar valves. We just refer to them at the left and right AV, so sometimes I fuck up the naming

I love you

godsend

Correct me if I am wrong, but isn't their a serous membrane known as the epicardium that surrounds the innermost layer of the pericardium, I am eleven years old and read this in a book and I am thinking this is correct

why aren't u my teacher??

Pulmonary Vein?

Nice and Helpful ...... Thank you

What about fibrous pericardium? Is it another layer outside the parietal pericardium?

@chuckmaddox6725

10 жыл бұрын

yes, you are correct

No... Atrio-Ventricular valves = Tricuspid and Bicuspid (a.k.a Mitral) Valves Semi-Lunar valves = Pulmonary and Aortic Valves

So is it possible for the Cordae Tendinae to break? And if so, if the blood flow goes the wrong directions, then what would happen?

i have one question what you call the barrier in the center of the heart?

Kindly request to you do you make your videos on animation.

epicardium then pericardium which consist of two layer

Mitral Regurgitation

How thick is each layer? Is it on a cellular level because I remember hearing you say the red blood cells bump the endocardium.

there is no such balloon, the epicardium "Visceral pericardium" is a different structure from the pericardium "parietal pericardium", the epicardium forms from the splanchnic mesoderm of the sinus venosus (not from Spetum Trasversum) where the pericardium is formed, instead, from the pleural (peritoneal) membrane!

Is there a name given to this, and what's the typical prognosis?

Oh you forgot the fibrous pericardium, the outermost layer.

Hi so may I ask what is the difference between endocardium and visceral pericardium?

The paricardial sac that I have heard of before is just in between the two layers of the pericardium?

@LFindable

Codidicus pericardial sac is the pericardium, therefore contains both visceral and parietal layer

pericardial cavity is between two layers of serous pericardium..

Is not in ventriculus dextra three papillares muscles?

Isn't there a layer called the the Epi - Cardium?

The time i broke my headphones: 8:45 And in that gap you might have A LITTLE BIT OF FLUID

(y) thank u ^-^

this isnt correct- there is one mitral/bicuspid valve and one tricuspid valve - exactly as he says in the video and exactly like the comment to which you responded.

and in that gap you MIGHT HAVE A LITTLE BIT OF FLUID!!!!!!..but it, uh

is he Elon musk

An ear rape at 8:52 plz fix.
