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 significant 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:

All the major vessels like arteries, arterioles, veins, and venules have a similar basic structure. They consist of four layers of tissue.

1. The innermost layer is the endothelium.

2. The layer next to the endothelium is elastic fibers.

3. A layer of smooth muscles (much thicker in arteries than in veins).

4. A layer of connective tissue.

The arteries carry oxygenated blood, but the pulmonary arteries carry deoxygenated blood towards the lungs. The oxygenated blood is also carried by pulmonary veins from the lungs to different parts of the body. The arteries are the blood vessels of the circulatory system that carry oxygenated blood to different tissues. The lymphatic system does not have a network of arteries, instead they have lymph vessels. .The atria push blood from veins to ventricles and it pushes blood to the arteries.

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
