Roles of the Systems
System Parts
Digestive System
Nervous System
Respiratory System
100

The system with the role of delivering oxygen and glucose to the cells of the body and then removing waste.

Circulatory System

100

Consists of bones and muscles working together.

Musculoskeletal System

100

Organs that convey food matter and process it.

Hollow Organs

100

Made up of the brain and spinal cord and acts as the control system for the body.

Central Nervous System

100

The location of the division between the upper and lower airways.

The Larynx

200

The system with the role of breaking down and absorbing ingested material, allowing it to be used for energy.

Digestive System

200

Comprised of the heart, blood, and blood vessels.

Circulatory System

200

Organs that create and secrete substances that assist with the chemical breakdown of food.

Solid Organs

200

Act as the communication lines, with nerves that relay information to and from the central nervous system.

Peripheral Nervous System

200

Consists of the nasopharynx and oropharynx.

Upper Respiratory Tract
300

The system that provides structure to the body, allows for movement, and physically protects the body's other systems.

Musculoskeletal System

300

Has three main layers: the epidermis, dermis, and subcutaneous layers.

Integumentary System

300

Organ that produces bile, the substance that helps with the absorption of fats by the intestines and detoxifies the blood.

Liver
300

A branch of the peripheral nervous system that is responsible for controlling voluntary muscle movements.

Somatic Nervous System

300

Made up of the trachea, bronchi, bronchioles, and lungs.

Lower Respiratory Tract

400

The system with the role of bringing oxygen from the air in contact with the blood inside microscopic capillaries.

Respiratory System

400

Divided into upper and lower tracts.

Respiratory System

400

The physical tube that connects the mouth to the stomach.

Esophagus

400

A division of the peripheral nervous system that controls and regulates the involuntary functions of the body.

Autonomic Nervous System

400

A sheet of muscle at the base of the lungs that pulls air into the airways by creating negative pressure in the chest.

Diaphragm

500

The system that provides the physical barrier between the inner systems of the body and the outside world.

Integumentary System

500

Divided into central and peripheral systems.

Nervous System

500

Organ that both physically grinds up food and chemically digests it with acid.

Stomach

500

The autonomic nervous system is divided into what two main branches referred to as the "fight or flight" and "rest and digest."

Sympathetic and Parasympathetic Nervous Systems

500

Organ with the physiologic function being the exchange of gases between the blood and the air.

Lungs
