my teacher taught me that Arteries - carry blood Away from the heart Veins - carry blood toVards the heart 😆😆

A nice way of knowing where the veins and arteries carry blood is in the name. 'V' in vein looks like a down arrow, pointing down towards the heart. 'A' in artery looks like an up arrow, pointing up away from the heart. Hope this helps!

i never really understood this topic but now i get it thank you !!

Thank you this video is so helpful!! I was so confused but I think I get it now (feel free to ignore this) Deoxygenated blood enters the heart from the body through the Vena Cava and into the right atrium, Oxygenated blood enters the heart from the lungs through the Pulmonary artery and into the left atrium, The atria contract together and pushed the blood into the ventricles, The ventricles contract together and push the : Deoxygenated blood into the pulmonary artery to be taken to the lungs, Oxygenated blood into the aorta to be taken to the rest of the body, while this happens the atria are being filled with new blood and the cycle repeats continuously.

@zoisapeers676

Жыл бұрын

Sorry, I don’t mean to be pedantic but the pulmonary artery carries blood away from the heart. A way to remember this is ‘artery’ has an ‘a’ in it, and so does ‘away’ so that should help 😊 ‘Pulmonary’ also means ‘lung’ so that might be helpful too :)

I don't know if You know or not, Pulmonary Vein/Artery only goes to the lungs. Plumonary means Lungs

Learning more than the textbooks itself.

The art style made me understand somehow
