Many organ systems
work together in the body of an organism
to perform its life functions
and to allow it to and carry out its daily activities.
There are eleven basic organ systems
found in vertebrate animals.
- Protects and supports internal organs and provides the structure needed to support movement. Forms blood cells and stores minerals.
- Creates movement, including locomotion and facial expression. Supports the body to create posture, and produces heat during movement.
- Electrical and chemical signaling system that controls body movements. Detects and responds to external and internal stimuli.
- Circulates gases, nutrients and wastes via the heart, blood vessels and circulatory fluid.
- Exchange of gases between the external and internal environments.
- Ingestion and breakdown of food to extract nutrients. Elimination of wastes.
- Elimination of nitrogenous wastes. Water, electrolyte and acid-base balance in bodily fluids.
