A system is a group of organs that work together and provide an organism with an advantage for survival.
It is the most complex organization in your body and the final level of the progression from cells to tissues to organs and then to systems.

Systems work alone and with other systems to allow your body to maintain homeostasis.
Homeostasis is a stable internal environment that allows you (and your cells) to survive.
The body has a lot of work to do to keep us alive and running. The body’s work is divided among organ systems, which are groups of organs and tissues that work together to perform a specific function.
These are the eleven basic organ systems:
- Nervous system
- Circulatory system
- Respiratory system
- Digestive system
- Skeletal system
- Muscular system
- Integumentary system
- Endocrine system
- Excretory system
- Reproductive system
- Immune system
