Functional organization of human body  Levels of body organization include the following: a- Cellular level b- Tissue level c- Organ level d- System level Functional organization of human body  Levels of body organization include the following: a- Cellular level : The cell is the basic structural and functional unit in the body. b- Tissue level : Tissue is formed of group of cells of similar shape and specialized functions. c- Organ level : The organ is composed of two or more tissues that perform a common function. d- System level (organ system): The system is composed of two or more organs that perform common functions. Functional organization of human body  Organ systems: 1- Nervous System 2- Endocrine (hormonal) System 3- Respiratory System 4- Cardiovascular System 5- Gastrointestinal System 6- Musculoskeletal System 7- Urinary System 8- Reproductive system 9- Immune system Functional organization of human body  Organ systems: 1- Nervous System (CNS & ANS): It is responsible for regulation, control, response to stimuli (excitation) and processing of (dealing with) information (excitation code).
