Human Body Systems

Inside the Human Body

The human body is made up of many systems that work together to keep us alive and healthy.

Major Systems

  • Circulatory System: Moves blood and oxygen throughout the body.
  • Respiratory System: Brings in oxygen and removes carbon dioxide.
  • Digestive System: Breaks down food for energy.
  • Nervous System: Controls body activities and responses.

Why It Matters

Understanding how body systems work helps us stay healthy, recognize problems, and seek proper treatment.

Real-World Uses

Doctors and nurses rely on knowledge of body systems to diagnose and treat patients.

Examples

  • An EMT checks a patient's breathing and pulse to assess vital systems.

  • A fitness coach designs workouts that strengthen the muscular and cardiovascular systems.

In a Nutshell

The human body is organized into systems that allow it to function and thrive.
