Body Builder Science Olympiad

Organ systems
A group of two or more organs working together for a specific job
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
Respiratory System
The body system where oxygen is brought into the body and carbon dioxide is released. It allows you to breathe.
Organs of the Respiratory System
nose, trachea, lungs, & diaphragm
Digestive System
The body system that takes in, breaks down, and absorbs nutrients that are necessary for growth
Organs of the Digestive System
mouth, esophagus, stomach, small intestine, large intestine
Nervous System
A body system made up of neurons that transmit signals from one body part to another. Think of this as your body's electrical wiring system.
Organs of the Nervous System
brain, spinal cord, & nerves
Central Nervous System
made up of the brain and spinal cord
Peripheral Nervous System
the neurons that connect the central nervous system to the rest of the body
carry messages to and from the body, so the brain can interpret them and take action.
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.
Endocrine System
Consists of glands that control many of the body's activities by producing hormones. This system plays a role in regulating mood, growth and development, tissue function, and metabolism.
a group of cells that produces and secretes, or gives off, chemicals.
Vitamins and Minerals
Compounds necessary for the healthy functioning of our bodies. They help us grow, to see correctly, to form bones, muscles, skin and organs, as well as to help us battle infections.
