Digestive System: Lower Gastrointestinal Tract
A section of the digestive system focused on chemical digestion and the absorption of nutrients. It contains the small intestine, large intestine and the rectum.
Got it
Digestive System: Upper Gastrointestinal Tract
This part of our digestive system is focused on bringing food into our bodies and performing some mechanical digestion. It includes our mouth, throat and stomach.
Got it
Digestive System
We use this system to break down and absorb the food we eat. It includes an upper and a lower tract.
Got it
Respiratory System
A body system that draws oxygen out of the air and distributes it to our blood. It contains our pharynx, larynx, trachea, bronchi and lungs, all of which contribute to the gas exchange process.
Got it
Cardiovascular System
The body system that transports blood and exchanges gases in the lungs. We have a closed system because our blood is carried in vessels. Our heart, arteries, veins and capillaries make up this system.
Got it
Musculoskeletal System
A word used to describe the body system that holds both our bones and our muscles, since these two parts of our body work so closely together to facilitate movement.
Got it
Muscular System
A body system that provides the strength needed to move. It is composed of voluntary muscle and involuntary muscle. We have cardiac muscle, smooth muscle and skeletal muscle cells in our body.
Got it
Skeletal System
This body system is made of bones and cartilage. As adults, we have 206 bones that offer support and structure to our bodies. This system also protects some of our organs and allows us to move.

Skeletal System
This body system is made of bones and cartilage. As adults, we have 206 bones that offer support and structure to our bodies. This system also protects some of our organs and allows us to move.
Muscular System
A body system that provides the strength needed to move. It is composed of voluntary muscle and involuntary muscle. We have cardiac muscle, smooth muscle and skeletal muscle cells in our body.
Musculoskeletal System
A word used to describe the body system that holds both our bones and our muscles, since these two parts of our body work so closely together to facilitate movement.
Cardiovascular System
The body system that transports blood and exchanges gases in the lungs. We have a closed system because our blood is carried in vessels. Our heart, arteries, veins and capillaries make up this system.
Respiratory System

Digestive System
We use this system to break down and absorb the food we eat. It includes an upper and a lower tract.
Digestive System: Upper Gastrointestinal Tract
This part of our digestive system is focused on bringing food into our bodies and performing some mechanical digestion. It includes our mouth, throat and stomach.
Digestive System: Lower Gastrointestinal Tract
A section of the digestive system focused on chemical digestion and the absorption of nutrients. It contains the small intestine, large intestine and the rectum.
Excretory System
The body system that removes waste from our bodies. Our liver, kidneys, bladder and urethra play important roles in this system by filtering out impurities from our blood.
Nervous System
This body system takes in sensory information, processes it and then responds to it in the correct way. We break it down into central, peripheral, autonomic and somatic systems.
Nervous System: Autonomic Nervous System
This portion of our nervous system controls involuntary body functions, such as breathing and sweating.
Nervous System: Somatic Nervous System
We use this portion of our nervous system when we respond to things voluntarily. It controls our senses.
Nervous System: Central Nervous System
We consider this to be the portion of our nervous system that includes our brain and spinal cord. It sorts out information and decides what to do.
Nervous System: Peripheral Nervous System
Sensory and motor neurons make up this portion of our nervous system. It absorbs information.
Immune System
A body system responsible for defending our body against invading pathogens. It can respond innately to some invaders. The use of vaccines and medications can aid this system.
Lymphatic System
A body system that brings lost fluid back to our bloodstreams. It carries lymph and exists outside of your closed circulatory system.
