Human Organ Systems Organs in the human body function as part of an integrated group of structures known as organ systems. Examples of organ systems are as follows:

• Cardiovascular system
• Digestive system
• Musculoskeletal system
• Nervous system
• Excretory system
• Endocrine system
• Respiratory system

These organ systems are responsible for crucial processes necessary for sustaining life, often working together, interacting with other organs in a functional network that keeps the body in balance (homeostasis). When homeostasis (the normal functioning of organ systems) is disrupted, disease may develop, causing injury to the body or even death.
