cycle of blood ( blood circulation)-
the Heartbeat circulates the blood in the human body.
• when the muscles of all the four Chambers of heart are relaxed the pulmonary veins brings the oxygenated blood from the lungs into the left Atrium of the heart
• when the left Atrium contracts the oxygenated blood is pushed into the left ventricle
• when the left ventricle contracts the oxygenated blood is forced into the main artery called arota this main artery than branches into smaller arteries which go into different body organs the smaller arteries further branch into capillaries.
• the main artery carries blood to all the organs of the body like head chest and stomach intestine liver kidney trunk and legs. when the oxygenated blood pass through the capillaries of body organs then it keeps oxygen to the body cell is the blood losses oxygen here we
say that blood has been deoxygenated. the deoxygenated blood from the body organs enters into the main vein called Vena cava the main vein carries deoxygenated blood to the right Atrium of the heart.
• when the right Atrium contracts deoxygenated blood is pushed into the right ventricle .
• and when the right ventricle contracts the deoxygenated blood is pumped into the lungs through the Pulmonary artery for purification.
