Mrs. Wharton’s Science Class Body Organization and Homeostasis

How is the Body Organized? Levels of organization in the human body consist of: Cells Tissues Organs Organ systems

Definitions Cell Basic unit of structure and function of living things. Examples: Blood cells, Bone cells, nerve cells, skin cells

Definitions Tissues Made of cells. Similar in structure and function and are joined together. Examples: Blood, bone tissue, nerve tissue, skin tissue, muscle tissue.

Definitions Organs Structure made of groups of different tissues that work together Examples: Heart, Brain, Kidney, liver, Skin, Lung, Bone , Stomach

Definitions Organ Systems Group of organs that work together to perform a specific function. Example: Circulatory system, Digestive system, Nervous system

Body Systems Different organ systems work together and depend on one another ( ie: riding a bike) Our body systems regulate the internal environment and strive to give our cells the necessary conditions they need to function. They work together to benefit the ENTIRE organism
