Which statement best describes the difference between atria and ventricles? a. atria push blood from the veins to the ventricles, and ventricles push blood from the atria to the arteries. b. atria push blood from the ventricles to the arteries, and ventricles push blood from the veins to the atria. c. atria are on the bottom of the heart, and ventricles are on the upper part of the heart. d. atria receive oxygenated blood, and ventricles receive deoxygenated blood.

The correct answer would be A. Atria push blood from the veins to the ventricles, and ventricles push blood from the atria to the arteries.

In double circulation, deoxygenated blood from all over the body is poured into the left atria of the heart with the help of vena cava. The atria then pumped the blood into the left ventricle which is located just below the left atria.

Left ventricle then pumps the blood to the lungs form oxygenation with the help of pulmonary arteries. Oxygenated blood from lungs is then pumped into the right atrium with the help of pulmonary veins.

Right atrium then pours the blood into the right ventricle (located just beneath the right atrium) which pumps the blood to all parts of the body with the help of aorta (largest artery).

Hence, we can conclude that Atria push blood from the veins to the ventricles, and ventricles push blood from the atria to the arteries.

The major difference between the atria and ventricle is that atria push blood from the veins to the ventricles, and ventricles push blood from the atria to the arteries.

Further Explanation:

The atria are the chambers that receive blood from veins. The atria contract and transfer the blood to the thick-walled chambers of the heart, called ventricles. The ventricles contract to pump the blood out of the heart.The blood will always flow from arteries to arterioles because arteries collect the blood from the heart and drain it into small arterioles that circulate this blood to the whole body. The arteries and veins are branched into small capillaries that distribute the blood to the different parts of the body. The walls of the capillaries have only an endothelium layer, so the ions and other solute molecules can easily diffuse out.The atria push blood from veins to ventricles, and it pushes blood to the arteries.
