Integumentary System

Organs: Skin and accessory organs (hair & nails)

Function: Protects tissue, regulates body temperature, and contains sensory organs

Skeletal System

Organs: Bones, cartilage, and ligaments

Function: Protects body parts, produce blood cells, and stores calcium and phosphorus salts

Organs: Skeletal, cardiac, and smooth muscles

Function: Moves voluntarily, responds to stimuli, and produces body heat

Nervous System

Organs: Brain, spinal cord, and nerves

Function: Conducts nerve impulses from the sense organs a to the brain and then to the muscles and glands

Endocrine System

Organs: Hypothalamus, pituitary, thyroid, parathyroid, adrenals, pancreas, ovaries, testes

Function: Secretes chemicals that are messengers between body parts, and maintains proper functioning of the reproductive system

Circulatory System

Organs: Nose, pharynx, larynx, trachea, lungs

Function: Bring oxygen into the lungs and take carbon dioxide out of the lungs

Digestive System

Organs: Mouth, pharynx, esophagus, stomach, small and large intestine, and rectum

Function: Receives food and digests it into nutrient molecules

Urinary System

Organs: Kidneys and urinary bladder

Function: Gets rid of nitrogenous wastes, and helps regulate the fluid level and chemical content of the blood

Reproductive System

Organs: (M) Testes, epididymis, vas deferens, urethra, penis; (F) Ovaries, fallopian tubes, uterus, vagina
