The heart uses the help of blood vessels to deliver blood into the body. The blood vessel, vein, has the duty to deliver deoxygenated blood to the heart. The deoxygenated blood pass into the heart from the right atrium with the help of diastole then the deoxygenated blood goes to the right ventricle and the right ventricle has the duty to deliver the deoxygenated blood to the lungs through pulmonary artery and the with the help atria’s diastole the right ventricle is able to deliver the deoxygenated blood to the lungs. The lungs give oxygen to the blood and it make the blood oxygenated. After that, the pulmonary veins have the job to deliver the oxygenated blood to left atrium. The oxygenated blood pass into the left atrium and with the help of ventricles’ diastole the blood goes to the left ventricle after passing the bicuspid valve.
