Circulatory/Cardiovascular System
The body system responsible for carrying materials throughout the body through arteries and veins
Organs of the Circulatory System
The heart and blood vessels

Spinal Cord
the main pathway for information connecting the brain and peripheral nervous system.
Muscular System
The body system that supports the body and enables it to MOVE and produce heat
Organs of the Muscular System
skeletal muscles, smooth muscles, and cardiac muscles
Smooth Muscles
You do not voluntarily control these muscles (they work without you having to think about it). They are found in soft organs of the body, and are responsible for processes like digestion of food.
Cardiac Muscles
Involuntary muscle responsible for pumping your heart. It is very strong and tough.
Skeletal Muscles
Voluntary muscles (you control them) that are attached to the skeleton and produce major movements of body parts.
Skeletal System
The body system that protects and supports the body
Major Organs of the Skeletal System
Bones (we have 206!)
Immune/Lymphatic System
The body system that kills pathogens (bacteria or viruses) that have invaded the body. It works to keep you healthy.

a group of cells that produces and secretes, or gives off, chemicals.
