Which system that fortifies and protects the body from infection is spread throughout the body and is not in only one region?
- Urinary system
The urinary system, which is responsible for the removal of waste products via urination, is located in one area, or region, of the body.
- Cardiac system
The cardiac system, which is responsible for pumping blood, is located in one area, or region, of the body.
- Immune system
The immune system is responsible for fortifying and protecting the body against infection. It is not located in one region of the body but spread out among many areas of the body.

The reproductive system, which is responsible for procreation, is located in one area, or region, of the body.
An organ system is a group of organs or structures that work together to perform certain functions in the human body.
Some organ systems in the human body (e.g. cardiac, reproductive, and urinary) are located and function within one region, or area, of the body. Other systems, including the immune system, are spread throughout the body. The primary role of the immune system is to fortify and protect the human body from infection.
