Interactions between Body Systems

Muscular System and Respiratory System

These systems interact when you inhale and the diaphragm contracts and pulls downward, while other muscles draw the ribs outward.

Nervous System, Muscular System, Skeletal System

These systems interact when you raise your hand and nerve tissue carries a message from your brain, and muscle tissue contracts to move the bones.

Excretory System, Digestive System, Respiratory System, and Skin

These systems/structures allow the body to remove wastes.

Respiratory System, Digestive System, and Skin

These systems/structures are the first lines of defense against pathogens that cause disease.

Lungs (Respiratory System) and Excretory System

These systems/structures interact to exchange exchange oxygen and carbon dioxide, and release waste products in cells.

Excretory System and Circulatory System

These systems interact when the kidneys filter materials out of the body.

Endocrine System

The glands of this system play an important role in reproduction (Reproductive System).

Muscular System and Respiratory System

These systems interact to allow the inhalation and exhalation of gases.

Circulatory System and Digestive System

These systems interact to transport digested materials to the cells of the body.

Nervous System and Digestive System

These systems interact when a message is sent from the brain to the stomach, triggering the sensation of hunger.

Digestive System and Muscular System

These systems interact when food is pushed down the esophagus to the stomach.

Endocrine System and Nervous System

These systems interact when glands of the brain control functions of the body.
