connects‚ supports‚ and protects body organs while distributing blood vessels to other tissue. Muscular tissue contracts to make body parts move and generates heat. Epithelial tissue covers body surfaces‚ lines hollow organs and cavities‚ and forms glands. Nervous tissues carry information from one part of the body to another through nerve impulses. Organs are structures that are composed of two or more different type of tissues. Each of them has specific function and usually has recognizable shape
