Today I will tell you about the path blood take through the body. The used blood enters the heart through the superior and inferior vena cava and the oxygen poor blood enters the right atrium.
The right atrium will contract and the non oxygenated will go through the tricuspid valve into the right ventricle
This should be fun!
The right ventricle will contract and the non oxygenated blood will go to the pulmonary artery where it will then be oxygenated. The blood that is now oxygenated will go through the pulmonary veins into the left atrium.
The left atrium will then contract, making the oxygenated blood flow into the left ventricle through the bicuspid valve.
I can't believe I am still explaining it even after 30 minutes of us walking.
It seems like a long process but its actually very simple. Thank you for telling me about the most important function of our body
Whew, Im almost done! The left ventricle contracts and the oxygenated blood will now leave the heart through the aortic semilunar valve to the capillary beds of the body.
