Describe the shape of the cells which carry blood around the body?

The red blood cells that transport oxygen in the blood are circular in shape with the center compressed - kind of like a donut, but where the hole would be is a "well" of tissue. It is shaped like this because this shape increases the surface area of the cell and allows it to carry more oxygen. The shape makes it more efficient.

Describe the shape of animal cells?

It has more to do with the rigid cell wall in a plant cell allows it to keep shape whereas animal cells can change shape freely. In theory, plant cells are like building blocks that make up the molecular system of a plant, so the inside of a plant is very organized. But, in an animal, the animal is alive and unpredictable, so the cells are very messy and sloppy. In fact, animal cells don't even always have a circular shape, they can be oval or not even make sense at all.
