RESPIRATORY Lungs, bronchi, alveoli Bring O2 into cells and CO2 out

CIRCULATORY Heart, blood, blood vessels Transports gases and nutrients around the body; gets rid of wastes from cells

SKELETAL Bones, cartilage ligaments Protects organs Structure Stores minerals Makes blood

MUSCULAR Muscles, tendons Movement, heat production

ENDOCRINE Glands, hormones Sends messages through blood to regulate body functions (EX: growth, metabolism, sexual development, sleep, hunger)

NERVOUS Brain, spinal cord, nerves Sends quick messages between the brain and body parts Senses

EXCRETORY Kidneys, bladder, urethra Cleans blood Eliminates liquid wastes Water balance

DIGESTIVE Esophagus, stomach, pancreas, small and large intestine … Brings food and water to the blood Eliminates solid wastes

IMMUNE Tonsils, spleen, white blood cells Protect the body from disease/ sickness
