What does a rat spleen look like?

A rat spleen typically has a dark red to purplish color and a smooth, oval shape. It is relatively small, about 1-2 centimeters in length, and has a soft, spongy texture. The surface may appear slightly wrinkled, and the organ is often surrounded by a thin capsule. Overall, the spleen is a vital part of the rat's immune system, playing a role in filtering blood and producing immune cells.
