Chapter 32
Structural Organisation in Animals
Your skin, the blood in your veins and the nerve that tells your finger to move look very different. Yet each is a tissue, a group of similar cells with one job. This chapter shows you the four basic tissues of an animal, how they join to make an organ and an organ system, and how all of it fits into one small animal, the cockroach. Python counts cells, times a nerve impulse and follows the life of a cockroach.
