A tissue is a group of cells that work together to perform a specific function in an organism. Tissues are a crucial level of organization in the biological hierarchy, situated between cells and organs. In multicellular organisms, tissues can be classified into four primary types:
1. **Epithelial Tissue**: This type covers body surfaces, lines cavities and organs, and forms glands. It serves various functions, including protection, absorption, secretion, and sensation.
2. **Connective Tissue**: This tissue supports, binds together, and protects tissues and organs of the body. It includes a variety of types, such as bone, adipose (fat) tissue, blood, and cartilage.
3. **Muscle Tissue**: This type is responsible for movement and is divided into three subtypes: skeletal muscle (voluntary movement), cardiac muscle (found in the heart), and smooth muscle (involuntary movement in internal organs).
4. **Nervous Tissue**: This tissue makes up the brain, spinal cord, and nerves. Its primary function is to transmit signals throughout the body, facilitating communication between different body parts and the coordination of bodily functions.
Each type of tissue has specific characteristics and functions, contributing to the overall health and functionality of an organism.
