Health & Medicine on Khan Academy: No organ quite symbolizes love like the heart. One reason may be that your heart helps you live, by moving ~5 liters (1.3 gallons) of blood through almost 100,000 kilometers (62,000 miles) of blood vessels every single minute! It has to do this all day, everyday, without ever taking a vacation! Now that is true love. Learn about how the heart works, how blood flows through the heart, where the blood goes after it leaves the heart, and what your heart is doing when it makes the sound “Lub Dub.”

What program are you using to illustrate? Great videos BTW. I'm an emt student, helps a ton.
i was playing music as i went to bed last night on my tv on youtube and i left it on autoplay and this autoplayed while i was asleep and it developed into a dream and i woke up and saw it playing on the tv and was very confused.
Lol
👏👏👍👍👏👏👍👍Amazing explanation
You are a great teacher. And artist : )
I love this channel!
Thank youuuuuuuuuu
great video
Superb
Thanks
thank you so much
;)
Volume is directly proportional to the pressure because higher volume per unit vessel indicates a bigger radius hence a slower rate of flow. Not inversely proportional(near the end of the video).
Thanks.
great video. However, mistake near the beginning; blood flow out of left ventricle illustrated on the wrong side. We all make mistakes though, even the most learned of men.
I think he means you would typically draw the left ventricle on the right side of the heart as you should be looking at it from the anatomical position.
Sir blood pressure konsi artery se lete h
Dose venules has valve?????
According to the book I'm studying, which is Seeley's Essential of Anatomy and Physiology 8th Edition, Elastic Arteries are the only largest arteries and the Muscular Arteries would be the medium-sized and the small arteries. (p.349)
yea
totally agree
Like for the Toe Cells
ok so its closed loop system, but still not understandable how arteriole become venule. How Arteriole loose for ex. its oxygen, nutrients ? It goes thru walls ? Or arteriole ends with hole and spread out all blood to tisues ? But then how blood presure is keept in Veins? Veins just suck in all blood like river from lake ?
The toe looked more like An arm
WOW!!! ))) faking love scenes
Ok 😊😊😊😊😊🤩🤩🤩
Hiiii
Why does he like toes so much?
The same thing I notice lol
Your heart and toe is really beautiful man....😁
