Explanation / Answer

please ask questions separtely and not all at once

1) D to pump blood with greater pressure

The left ventricle needs to be thicker than the right because it needs to pump blood through the entire body and hence higher pressure is needed, more muscle mass is needed and hence the thicker wall is present.

The right ventricle only pumps blood to the lungs which doesnt require as much pressure
2) D Carbon dioxide moves from its production site into the interstitial fluid

3) D contains the serous fluid.

It is the space between the layers of the serous pericardium and contains serous fluid which is a lubricating fluid

4)C Coronary arteries
