Human Body System

Which organ is part of the peripheral nervous system?

• Brain

• Heart

• Nerves

• Hair

Muscular tube connecting the mouth to the stomach

• Esophagus

• Small Intestine

• Phagocytes

• Spinal Cord

Arteries

• Blood vessel that carries oxygen rich blood away from the heart and to the body parts.

• Carries oxygen poor blood (with carbon dioxide) back to the heart to be pumped out to the lungs.

• Hollow, muscular organ that pumps blood throughout the body.

•  Small blood vessels where materials are exchanged between the blood and the body’s cells (oxygen and carbon dioxide)

Mucus and Cilia

• White blood cells that engulf and destroy pathogens

• Waste material is compressed into solid form

• Trap and remove pathogens that enter the respiratory system

•  Mechanical and chemical digestion start here

Large dome-shaped muscle used in breathing

• Diaphragm

• Heart

• Kidney

• Smooth Muscles

Mouth

• Skeletal System

• Digestive System

• Respiratory System

• Circulatory System

Cartilage

• Connective tissue that is more flexible than bone

• Found only in the heart

• Link between brain and the rest of the body

•  Small blood vessels where materials are exchanged between the blood and the body’s cells

Neurons

• Attached to bone and move bones using tendons

• Water absorbed into the bloodstream, remaining material is readied for elimination from the body.

• Produce chemical called antibodies to destroy pathogens 

• Nerve cell specialized to transfer messages in the form of fast-moving electrical energy 

Lungs

• Small blood vessels where materials are exchanged between the blood and the body’s cells (oxygen and carbon dioxide)

• Where the exchange of gas occurs. Oxygen enters and carbon dioxide exits.

• Muscular tube connecting the mouth to the stomach

• Force pathogens out of the body

Controls most functions in the body.

• Skeleton

• Immune System

• Brain

• Skin
