The Pathway of Blood Flow Through the Heart Animated Tutorial.


The pathway of blood flow through the heart.
Oxygen-poor blood from your body returns to the right atrium of the heart. Blood from
upper body returns through superior vena cava, blood from lower body returns through inferior
vena cava. As the right atrium is filled with blood, it contracts, the tricuspid valve opens
and blood is pumped into the right ventricle of your heart. When the right ventricle is
full, the tricuspid valve closes to prevent blood from flowing back into the atrium. The
right ventricle contracts, pulmonary valve opens and blood is pumped into the pulmonary
artery and to your lungs. Pulmonary valve closes to prevent blood from flowing back
into the ventricle. Oxygen-rich blood from the lungs returns to
the left atrium of the heart. As the left atrium is filled with blood, it contracts,
the mitral valve opens and blood is pumped into the left ventricle of your heart. This
occurs at the same time as the right atrium pumps blood into the right ventricle on the
other side of the heart. As the left ventricle is full, the mitral valve closes, the aortic
valve opens, the left ventricle contracts and oxygen-rich blood is pumped into the aorta
to reach all parts of your body. This happens at the same time as the right ventricle pumps
blood into the pulmonary artery on the other side of the heart. The aortic valve quickly
closes to prevent blood from flowing back to the heart. Meanwhile, the atria have filled
with blood and the cycle repeats itself.

  1. Can't thank you enough, I read a lot about this and watched lessons but couldn't picture it well. This really made it clearer for me 🙂

  2. Just a thing here. There are no airspaces in the heart when the pumping of blood occurs, if there were then the blood would start to dry out and form a clot in your circulatory system. But otherwise great video!

  3. I can't stop laughing because this reminds me of my chickens. Whenever you pick one up off the floor, they get so scared and nervous that their little hearts just pick right up and you can feel it beat rapidly against your hand. Bird heart… Fast.

  4. I had a test 2 days ago and i didnt study so i was studying in the bus, and i watched this video about 5 to 8 times. and i got a 100 on my test!! Thank you!

  5. Why do teachers make it seem so complicated? Despite not elaborating on veins and arteries, this answered all of my questions.

  6. thanks a lot for uploading such a beautiful video. now its seems easy for me.
    love from Bangladesh 😍

  8. remember too the other commonly used names for the valves:
    tricuspid valve = right atrioventricular (AV) valve
    pulmonary valve = pulmonary semilunar valve
    mitral valve = biscupid valve = left atrioventricular (AV) valve
    aortic valve = aortic semilunar valve

  9. Thank you so much 😭😭 It helped me a lot since I really don't get the flow of blood because I was getting sleepy while my Teacher is explaining.

  10. Blood Circulation:
    Superior/Inferior Venacava -> right auricle/atrium -> tricuspid valve -> right ventricle -> pulmonary valve -> pulmonary artery -> lungs -> left auricle/atrium -> mitral valve -> left ventricle -> aortic valve -> aorta -> to the diff. parts of the body.
    Well, that is our lesson in Science….
    I'm just 12 Y.O and in 6th grade…

  11. This is a very good video. Thank you. I am using it now to help teach my Grade 6 students about the heart. I wonder if you would consider allowing the video to play within another website, i.e., a Google Slides presentation?

  12. To whoever wants this… (Copied this from the video).

  13. Hi All Of You.

    Bro/Sis
    I like to learn study of public health so give any information about this if you know please?
    Thanks👍

  14. I understand that this is an oversimplification but I think that it isn’t quite misleading.

    This video seems to show that there is air inside the heart and the blood vessels when in reality there obviously is none.

    I think that this video could have represented the heart more accurately without losing its simplicity.

  15. The blood flow into the venricles passively when mitral and tricuspid valves are open , and the atria just contract at the latest 3rd of flow duration
