Tissues of the human body?

The cell is the smallest fraction of every living being.
The simplest forms of plants and animals are composed of only one cell.
Within the more complex living beings cells work together, organized into groups, each of which has its own task.

Tissue is a group of cells of the same type that performs specific task.

There is, for example, bone tissue, etc. The tissues are grouped to perform a specific job; such group is called body tissues. For example, the human hand is composed of different tissues: bones, muscles, nerves, etc.
In the human body there are five major types of cells. 
  • Epithelial or cover cells build the skin, glands, and line the blood vessels. 
  • Muscle cells built up three types of muscles. 
  • Nerve cells constitute the brain, spinal cord and nerves. 
  • Blood cells are found in lymph. 
  • The binding cells of the human body form the connective tissue, which is the supporting tissue.
