Integumentary System

Forms the body's external covering; protects deeper tissue from injury; helps regulate body temperature - skin, hair, nails

Skeletal System

Protects and supports body organs; provides a framework the muscles can use to cause movement; stores minerals - bones, joints

Muscular System

Moves the body and moves substances around the body; maintains posture; produces body heat - skeletal muscle, cardiac muscle, smooth muscle

Nervous System

Responds to internal and external changes by activating appropriate response; process information - brain, spinal cord, sensory receptors, nerves

Cardiovascular system

Pumps blood around body; transports oxygen, carbon dioxide, nutrients, and waste - heart, blood vessels (veins, arteries, and capillaries)

Respiratory System

Assists with gas exchange with the external environment; keeps blood supplied with oxygen and removes carbon dioxide - lungs, nasal cavity, trachea, bonchus

Lymphatic and Immune System

Filters fluid in the body; mounts the attack against foreign substances in the body - lymph nodes, spleen, thymus, bone marrow

Digestive System
