-Tissues are formed of cells with similar morphology, function and an extracellular matrix. Examples of tissues include cartilage, bone, and muscles.
-Organs are groups of tissues that act together to perform specific functions. Tissues and organs can comprise integrated functional systems that form major anatomical entities - e.g. the gastrointestinal tract. Within tissues, cells interact with each other in various ways during embryological development, growth maintenance, and response to injury.
