She means that the heart muscle itself is supplied by coronary arteries, left & right. They come from the aorta. The aorta supplies blood to the rest of the body. Vena cavae just bring blood to the heart chambers to be eventually delivered to the lungs for oxygenation. Once the blood is oxygenated, it goes back to the heart and is pumped to the systemic circulation once the heart contracts (systole). As the heart relaxes (diastole), that's when the coronary A bring blood to the heart muscle.
Don't be sarcastic because in reality, she is talking "advanced" knowledge. I do not believe that a person without medical background can fully understand her. She just makes it easy for everyone to grasp the concepts behind common clinical procedures. I have taken basic CPR and nowhere it is being taught like this speaker in this video presented it to the online audience.
I beg your pardon, but it is probably better to be a little bit humble. We learn more that way.
I think the great AORTA actually LEAVES the heart, and that is the biggest ARTERY in your body (I think). So the way I was taught, veins come back IN 2 the heart and/or the pulmonary system.
The large veins (vena cavae) bring unoxygenated blood to the heart, then the blood goes through the pulmonary artery to be delivered to the lungs where there is exchanged of oxygen and carbon dioxide. The oxygenatedd blood is delivered to the heart via the pulmonary VEIN and it passes through the mitral valve, then to the aorta, then to the general circulation.
thank you for sharing it is very nice

Its scary medical students don't know this intuitively.

"Your heart is supplied by two arteries"
It's supposed to be veins, right?
mewboy23799 3 years ago
no oxygenated blood is delivered to the heart by the left and right coronary arteries
referring to:
supplied to the hart tissue, the myocardium not returned to the heart by the inf. and sup. vena cava to pump.

no, two main coronary arteries.

No you,re not. She is talking about the two main coronary arteries...
