HOW DOES BLOOD CIRCULATE THROUGHOUT THE BODY ?
Answers
Answer:
Blood comes into the right atrium from the body, moves into the right ventricle and is pushed into the pulmonary arteries in the lungs. After picking up oxygen, the blood travels back to the heart through the pulmonary veins into the left atrium, to the left ventricle and out to the body's tissues through the aorta.

Explanation:
The blood circulation starts from the vein that comes from the body to vena cava and then the de-oxidized blood enters the right auricle, then the blood enters the right ventricle through tricuspid valve.After entering to right ventricle,the blood goes to the lungs through pulmonary artery and there the blood is oxidized and comes to the left auricle through pulmonary vein and then the blood enters left ventricle through bicuspid valve. After entering to left ventricle the blood goes to the body parts through arteries and the part that connects left ventricle with arteries is called aorta and the blood comes from the body parts to vena cava through veins and the process is repeated again and again
