Final answer:
The blood flows from the right atrium to the left ventricle through the pulmonary artery and returns to the aorta.
Step-by-step explanation:
The correct answer is C) RA to RV to pulmonary artery to LA to LV to aorta.
When blood flows through the heart, it enters through the right atrium (RA) from the body, then goes to the right ventricle (RV) and is pumped to the lungs through the pulmonary artery. After oxygenation in the lungs, the blood returns to the left atrium (LA) and then to the left ventricle (LV). From the LV, blood is pumped into the aorta, which distributes it to the rest of the body.
For example, let's consider the flow of blood from the right atrium to the left ventricle. When blood enters the right atrium, it then moves to the right ventricle and is pumped into the pulmonary artery. After being oxygenated in the lungs, the blood then returns to the left atrium and moves to the left ventricle. Finally, it is pumped out of the left ventricle into the aorta and circulated throughout the body.
