Blood comes into the heart by veins
-
Blood comes thru the veins into the vena cava by the superior and inferior openings.
-
After passing through the Vena Cava, blood then goes into the right atrium.
-
After going thru the right atrium, blood then passes to the tricuspid valve.
-
-
Once in the right ventricle, the blood travels up to the pulmonary valve.
-
When coming out of the pulmonary valve, blood travels out of the heart to the lungs by the pulmonary artery.
-
blood goes into the lungs where oxygen and carbon dioxide exchange.
-
Oxygenated blood comes from lungs thru the pulmonary veins.
-
Coming from the pulmonary veins, oxygenated blood arrives at the left atrium.
