Final Answer:
The atria receive blood carried by veins toward the heart because they function as receiving chambers for deoxygenated blood returning from the body.
So. C) Atria receive blood carried by veins toward the heart is correct.
Step-by-step explanation:
The accurate statement regarding the heart's chambers and their function in blood flow is that the atria receive blood carried by veins toward the heart. The heart consists of four chambers: two atria and two ventricles.
The atria function as receiving chambers, receiving blood from the body via veins (which carry deoxygenated blood) and pumping it into the ventricles. The ventricles, in turn, pump blood away from the heart into the arteries. This circulation allows for oxygenated blood to be sent out to the body and deoxygenated blood to return to the heart.
In the circulatory system, blood flows through a network of arteries and veins. Arteries carry oxygenated blood away from the heart to the body, while veins carry deoxygenated blood back to the heart.
The atria's role is to collect this returning deoxygenated blood from the veins and send it to the ventricles for subsequent pumping into the lungs for oxygenation (right side of the heart) or to the rest of the body (left side of the heart).
The ventricles, on the other hand, are the pumping chambers responsible for ejecting blood into the respective circulatory pathways—arteries from the left ventricle and pulmonary arteries from the right ventricle.
Understanding this directional flow of blood within the heart's chambers is crucial in comprehending the heart's functioning in maintaining circulation and providing oxygenated blood to the body's tissues.
It's a coordinated process where each chamber's specific function ensures an efficient circulation of oxygenated and deoxygenated blood throughout the body.
So. C) Atria receive blood carried by veins toward the heart is correct.
