and several arterial branches derived from it, which carry blood to the corresponding organs. The artery then branches several times, the diameter of the tube gradually narrows, the number of blood vessels gradually increases, and finally reaches the capillaries, where the intercellular fluid is exchanged with the tissue cells. Oxygen and nutrients in the blood are absorbed by the tissues, while carbon dioxide in the tissues.
and other metabolites enter the bloodstream, turning arterial blood into venous blood. The veins gradually thicken and decrease in number, until finally all the veins converge into the superior and inferior vena cava, from which blood returns to the left atrium, thus completing the systemic process. Pulmonary circulation begins in the right ventricle.
Venous blood is pulsed out of the right ventricle and travels through the pulmonary artery to the capillary network around the alveoli, where it excretes carbon dioxide, absorbs fresh oxygen, transforms venous blood into arterial blood, and then flows back to the left atrium through the pulmonary veins. Blood from the left atrium re-enters the left ventricle and circulates again.
All over the body. In this way, the blood is continuously running through the systemic and pulmonary circulation, completing the important task of blood circulation.
