List of major human organ systems

There are typically considered to be eleven major organ systems of the human body.

• Digestive system - Absorption of nutrients and excretion of waste.

• Skeletal system - Support and movement, lymphocyte production

• Muscular system - Support and movement, production of heat

• Nervous system - Integration and coordination through electrochemical signals

• Endocrine system - Integration and coordination through hormones

• Respiratory system - Elimination of CO₂ and absorption of O₂

• Circulatory system - The transporting of needed materials to the cells and the transporting of wastes away from the cells.

• Reproductive system - Production of offspring.

• Integumentary system - Body covering

• Lymphatic system - Regulate fluids and immunity

• Urinary system - Excretion of nitrogenous waste, and maintain homeostasis of electrolytes
