Animal Tissues

Tissues are groups of similar cells that perform a particular function. We will be examining human tissues as an example of animal tissues.

Human bodies, like most animal bodies are made up of four different types of tissue:

  1. Epithelial tissue forms the outer layer of the body and also lines many of the bodies cavities where it has a protective function.
  2. Connective tissue assists in support and protection of organs and limbs and depending on the location in the body it may join or separate organs or parts of the body.
  3. Muscle tissue enables various forms of movement, both voluntary and involuntary.
  4. Nerve tissue is responsible for the carrying of electrical and chemical signals and impulses from the brain and central nervous system to the periphery, and vice versa.

We will now look at each tissue type, examining its structure and function as well as its specific location in the body. You will be expected to recognise microscope images of each tissue type and from them produce biological drawings.

The optional video below talks about the different tissue types in animals.
