The following is a list of vessels and structures that are associated with the heart. 1. right atrium 2. left atrium 3. right ventricle 4. left ventricle 5. venae cavae 6. aorta 7. pulmonary trunk 8. pulmonary veins What is the correct order for the flow of blood entering from the systemic circulation?

Respuesta :

Answer:

8. pulmonary veins, 2. left atrium, 4. left ventricle, 6. aorta,

5. venae cavae,  1. right atrium, 3. right ventricle, 7. pulmonary trunk

Explanation:

The heart maintains the flow of blood with the help of veins and arteries. The pulmonary veins transfers oxygenated blood from lungs to left atrium that contracts and releases blood into left ventricle and further to aorta and then to the body.

The deoxygenated blood transfers from the venae cavae to right atrium that contracts and releases blood to right ventricle. It transfers blood to pulmonary trunk which divides to pulmonary arteries that flows deoxygenated blood to lungs for oxygenation.

The correct order for the flow of blood entering from the systemic circulation is from pulmonary veins to left atrium to left ventricle to aorta to vena cavae to right atrium to right ventricle and finally to pulmonary trunk.

What is systemic circulation?

The functional blood supply is provided to all the tissues of the body via systemic circulation. It mediates nutrients and oxygen to the cells and picks up waste products and carbon dioxide. This form of circulation carries oxygenated blood from the left ventricle, via the arteries, to the capillaries in the body tissues.

The flow of blood is maintained by the heart with the assistance of veins and arteries. The oxygenated blood from the lungs to the left atrium is transferred by the pulmonary veins. The left atrium contracts and discharges blood into the left ventricle, which is further transferred to aorta and then to the body.

With the help of vena cavae, the deoxygenated blood is transferred to the right atrium, which further contracts and discharges blood to the right ventricle. From the right ventricle, the blood is transferred to the pulmonary trunk, which differentiates into pulmonary arteries that mediates deoxygenated blood to the lungs for oxygenation.

Thus, the correct order is 8, 2, 4, 6, 5, 1, 3 and 7.
