The tissue is a group of cells connected to each other that collectively perform similar functions in an organism. All contents of the body including structures and various organs are made of tissues.
The animal body comprises of four basic types of tissues, all of which vary in their origin and function. They are:
Epithelial Tissues- Made of tightly packed cells layer together, epithelial tissues line the body surface. Their functions include protection, absorption, and secretion. Epithelial tissues can be found in the lining of the mouth and nose, digestive system lining, and the skin.
Muscle Tissues- These are of three types, smooth muscle tissue- found in inner linings of organs, skeletal muscle tissue- found attached to the bone and helps in body movement and cardiac muscle tissue- found in the heart. These tissues help in changing the size of a cell.
Nervous Tissues- Made up of neurons (nerve cells in the brain), these tissues form the entire nervous system, including the spinal cord and the brain.
Connective Tissues- Made of various cells that are involved in lending support to the body, connective tissues are namely the fat, bone, blood and cartilage in an animal body.
