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.

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 ).

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.

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.

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!
