Answered by sijisunil4r

Answer:

Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.

Answer: sure ok so the blood comes back to the heart through the pulmonary artery, then to the heart though the right atrium flows down to the right ventricle (also its important to remember that the sides are flipped as you are viewing them from another angle basically the right is left and the left is right) back to the answer from right ventricle to the lungs through pulmonary artery then back to the heart and finally pumped to the body you can find vids that might be a bit more helpful
