Detailed explanation-1: -As we saw above, every organ is made up of two or more tissues, groups of similar cells that work together to perform a specific task. Humans-and other large multicellular animals-are made up of four basic tissue types: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.

Detailed explanation-2: -Organ-a group of tissues precisely arranged so that they can work together to perform specific functions. Examples include: Liver. Brain.

Detailed explanation-3: -Tissues are collections of cells which serve the same function while organs are collections of tissues. Organ systems are composed of groups of organs with the same purpose and function. The types of tissues include epithelial, connective, nervous and muscle.

Detailed explanation-4: -The Group of tissues performing particular functions in the body is called an organ or an organ is a structure composed of at least two or more tissue types. Each tissue performs a specific function of the body. Several organs together constitute an organ system.

Detailed explanation-5: -A group of organs working together to perform a specific function is called an organ system. An example of an organ system is the circulatory system, which includes different organs like the heart, arteries, veins, and capillaries.
