Tissues are formed by groups of cells working together from "summary" of Anatomy & Physiology by Kevin T. Patton
Tissues are the fundamental building blocks of the human body. They are made up of groups of cells that work together to perform a specific function. These cells are specialized to carry out particular tasks within the tissue. There are four main types of tissues in the body: epithelial, connective, muscle, and nervous. Epithelial tissue covers the body surfaces, lines hollow organs, and forms glands. Connective tissue provides support and structure for the body. Muscle tissue is responsible for movement, while nervous tissue transmits electrical signals throughout the body. Each type of tissue is made up of different types of cells that are organized in a specific way to carry out their function. For example, epithelial tissue is made up of closely packed cells that form a protective barrier. Connective tissue contains cells dispersed in an extracellular matrix that provides support and strength. Within each tissue, cells communicate with each other to coordinate their activities. This communication is essential for the tissue to function properly. Cells in epithelial tissue, for example, work together to form a barrier that protects underlying tissues from injury and infection.- Tissues are formed by groups of cells that work together to perform a specific function in the body. Each type of tissue is made up of specialized cells that are organized in a specific way to carry out their role. Communication between cells is essential for the proper functioning of tissues.
