Tissues are made of cells that are specialized for particular functions in the body. Cells are the basic living structure of the human body but when they are organized into tissues their activity becomes more specialized. The human body has four primary types of tissue : connective tissues, epithelial tissues, nerve tissues and muscular tissues.
Connective tissues are all over the body. They bind structures together. They also provide support and protection. Connective tissue includes tendons, ligaments, bone and cartilage. Other types of this tissue store fat, produce blood cells and destroy bacteria.
Epithelial tissues cover the whole body inside and out. They form the skin, and the inner lining of the body cavities such as the stomach and the intestines. Epithelial tissue can reproduce quickly in case of damage or injury. That’s why your skin heals so quickly when you get a cut.
Nerve tissues are sensitive to changes. They receive and transmit impulses to various parts of the body. They are located in the brain, spinal cord and the nerves.
Muscle tissues are probably the ones you are most familiar with. Their function is to contract and cause body parts to move. There are three types of muscle tissue skeletal muscle, smooth muscle, and cardiac muscle.
