What are the three kinds of blood vessels and what are their functions?

Arteries carry blood with fresh oxygen around the body. Capillaries are at the end of the arteries and they deliver the oxygen to cells and pick up the carbon dioxide from the cells. Then they are connected to the veins and deliver the blood with the carbon dioxide to the veins. Veins carry blood with carbon dioxide in it back to the heart.

How do the cells in multicellular organisms get the resources they need to stay alive?

Blood delivers food & gases to the cells.

How does blood entering the right atrium differ from blood entering the left atrium?

Blood entering the left atrium is coming from the lungs and is filled with fresh oxygen. Blood entering the right atrium is returning from around the body and it is filled with carbon dioxide.
