How do tissues contribute to physiological functions?
Tissues are groups of cells that work together to perform specific functions. There are four primary tissue types: epithelial, connective, muscle, and nervous tissues. Each type plays a vital role in physiological processes. For instance, epithelial tissue forms protective barriers and is involved in absorption, secretion, and sensation. Connective tissue provides support and structure to organs, while muscle tissue enables movement through contraction. Nervous tissue is responsible for transmitting signals and coordinating bodily functions.
