Nutrients, wastes, and gases. How many organ systems are there? Eleven Integumentary System It provides protection (skin, hair, and nails) Skeletal System Provides support and protection, site of blood cell protection, STORES CALCIUM AND PHOSPHORUS (the skeletal and muscular system work together) (bones and joints) Muscular System Produces body movement and generates heat (skeletal muscles, tendons) Nervous System Controls body movement (most important system) (brain, spinal cord, and nerves) Urinary System filters blood and removes waste produces (kidneys, uterus, bladder,urethra) Digestive System digests food materials, absorbs nutrients, and expels waste products (oral cavity, esophagus, liver, stomach, small intestine, large intestine, rectum, and anus.)
