Circulation is a process in which the heart and blood vessels intervene, occurs as follows:
- Blood enters the right atrium of the heart, then leaves through the right ventricle and thus begins the pulmonary circulation.
- This blood is then carried through the pulmonary trunk (arteries) to the lungs where oxygen is administered, to finally go through the pulmonary veins to the left atrium and out through the left ventricle to the aorta.
That is, oxygenated blood is carried from lungs, pulmonary veins, left atrium, left ventricle, aorta.
- Oxygen-poor blood flows against the force of gravity through the veins back to the heart, where it passes through the superior vena cava back to the right atrium.
That is, deoxygenated blood is transported from superior vena cava, right atrium, right ventricle, pulmonary artery, lungs.
Therefore, we can conclude that the blood goes through an oxygenation process that is carried out by the blood vessels, the heart and the lungs, so if any of these structures is affected, the entire circulation system will be altered.
