Living tissues are groups of similar cells that work together to perform a specific function. The formation of tissues can occur In animal and plant cells. Similarly, different types of tissues are present in the human body, such as the epithelial, connective, muscular and nervous tissues.
Each tissue type has a specific function. For example, epithelial tissue covers the body's surface. There are different types of epithelial tissue, including columnar and cuboidal.
While muscular tissue is necessary for the movement of different body parts, connective tissue helps to anchor these body parts. Similar to epithelial tissue, there are different kinds of both muscle and connective tissues, such as smooth and skeletal muscles, and cartilage and blood tissues. Nervous tissue is a specialized type of tissue that reacts to different stimuli, and can conduct impulses to body organs.
