In a nutshell: Body systems must work together to maintain health and respond to challenges.
## How Systems Work Together for Survival
The human body is made up of many organ systems that must communicate and coordinate for healthy function.
### Nervous and Endocrine Systems
The nervous system uses electrical signals, while the endocrine system uses hormones to regulate body processes.
### Circulatory and Respiratory Systems
These systems work together to deliver oxygen and nutrients to tissues and remove waste.
### Immune System
Protects the body from pathogens using a complex network of cells and molecules.
### Medical Connections
Understanding system integration is vital for diagnosing diseases and developing treatments that target multiple systems.
