Final answer:
The correct sequence for blood flow through the heart is: Right Atrium → Right Ventricle → Left Atrium → Left Ventricle. Blood enters the heart at the right atrium, is pumped to the right ventricle, goes to the lungs, returns to the left atrium, and is finally pumped out to the body by the left ventricle.
Step-by-step explanation:
The correct path of blood flow through the heart is: Right Atrium → Right Ventricle → Left Atrium → Left Ventricle.
Blood from the body enters the heart through the right atrium via venues like the superior vena cava and the inferior vena cava. The right atrium then contracts, pushing blood through the tricuspid valve into the right ventricle, which, upon contraction, sends the blood to the lungs through the pulmonary arteries for gas exchange.
Oxygenated blood returns to the heart via the pulmonary veins, entering the left atrium. The left atrium contracts sending blood through the mitral valve into the left ventricle. Finally, the left ventricle contracts, pumping oxygen-rich blood to the rest of the body through the aorta.
