This video doesn't go into the electrical system of the heart, but here is a good source from NIH that does!

Why do veins appear the color they do under the skin (when human blood is red)? This is a great read from The Conversation (a nonprofit organization that uses fact- and research-based journalism).

The feeling when someone manages to talk about everything my teacher has been struggling for 2 weeks to get it into us in less than 10 minutes...

[karii]

I love how people keep watching even though school has barely started and they're probably not assigned to us. You're so entertaining:D

Notes:
-Blood is red not blue
-Blood maintains pH and temp
-Transports hormones nutrients gasses
-Made of plasma(liquid), cellular components (red, white blood cells & platelets)
-arteries carry blood away from the heart
-veins carry blood to the heart
-capillaries deliver oxygen
-heart:
•r deoxygenated blood L oxygenated blood
•atrium thin walls
•ventricles thick
•needs it's own blood supply
•beats 100, 000+ times daily
•anatomic differences change blood pathway flow meaning oxygen rich/poor blood can be mixed causing complications

anyone watching this the day before their exam?

[jaclynlockwood]

Omg this is so weird I am literally taking Anatomy 2 right now and I was just reading all about the heart today. I was just thinking today I wish amoeba sisters would upload a video on the heart and YOU DID. You have no idea how happy I am right now. I got an A in biology because of you ❤️❤️❤️

[katelynvalenzuela]

I’ve been having a tough time understanding how the blood moves through the heart but you explained it perfectly, thank you so much!

[tanaybhomia]

You know what this is the best biology channel on youtube universally

[major_gamboge]

I can’t believe we have access to such AMAZING videos for free!

[MAGGIET-llue]

These drawings are incredible! Petunia you’re a genius! 4th comment, I suppose.

[CryptoKing]

This is the most underrated YouTube channel ever.. You guys deserve an Oscar Award for the Best Biology YouTube channel ever😩😩

[dragonblade]

This is the only 'pamphlet' I would never throw away after getting it.

[punusername]

I suggested this channel to my biology teacher, now he always use of this drawings in his slideshows

[chrystalzhou]

I just discovered this channel this summer. Why couldn't youtube have brought it to me earlier? It is a great channel, and even though I don't use this for school as often (school hasn't started), it teaches me SO much and is so fun to watch. The Amoeba Sisters are the BEST!

[newchapter-mylife]

I love your videos. They are so clear and I can understand the video so well. Science is my favorite topic so I usually search for science videos to clear my doubts and I'm so glad I have come across Amoeba Sisters. Your videos explain in detail without giving the "Boringness" that usually shadows us all when we are learning hard and complicated topics in detail. These videos give a will to learn more and even makes us learn topics befor our teachers even introduce them to us! Thank You So much for making my love in science even stronger and for clearing my doubts.

Thanks Again Amoeba Sisters!!!

[thatliquidthing]

I was absolutely *PUMPED* when I saw your new video! Also, the heart has two of my favorite words: aorta and ventricle!

[mastikitrain]

Great video, mam.
I'm in 10th grade (India) and we've got this chapter- "Life Processes" in Bio and Transportation (in humans and plants) is a major part of the chapter. And this video was such an amazing summarised version of this topic- Transportation in Humans.

[highvalue]

Whoever made this deserves an award 🤩 thank you!!! This moves fast and efficient for my brain. Keeps me interested the whole video.

[Jeff-jzhu]

Why are there 5 dislikes when this is so educative? It took Petunia hard work and Pinky too

[carlosvijasuarez]

I always recommend this channel to my students, is really helpful for them. Thanks so much for every job that you do.

[NotAriieFluffie]
