Each of the body systems that help keep you alive (from left to right): digestive, nervous, skeletal, Cardiovascular and pulmonary.
From birth, these systems function autonomically to carry out a range of tasks:
- Digesting food to collect and store energy.
- Sending signals that translate to movement, both voluntary and involuntary (known as reflexes that help you react to the unexpected).
- The skeleton supports the body by holding everything in position, it protects of your vital organs and also helps with movement by providing joints.
- The cardiovascular system pumps blood around the body as a means of carrying oxygen into muscles and organs and taking carbon dioxide out of the body.
- The blood carries nutrients around the body to where they are needed.
- The pulmonary system includes the lungs, throat and mouth. It allows us to breathe in oxygen and expel carbon dioxide, as well as speak.
