Answer :

Humans are composed of different types of tissues.

However, there are four basic types of tissues in the human body which are as follows:

  1. Epithelial tissue
  2. Connective tissue
  3. Muscular tissue
  4. Nervous tissue

Each type of tissue has its specific function in the human body. Epithelial tissue is a  group of cells that cover the exterior surfaces of the body, line internal cavities and passageways, and form certain glands. It acts as a protective layer. Connective tissue is a type of tissue that binds the cells and organs of the body together. Muscular tissue contracts forcefully when excited, providing movement.  Nervous tissue is also excitable, allowing for the generation and propagation of electrochemical signals in the form of nerve impulses that communicate between different regions of the body through the signals.

A complete study of the various primary tissue types and other types of tissues present in the human body is essential for understanding the structure and function of organs that are composed of two or more primary tissue types.
