2 Interdependence of Organ Systems Our organs do not work in isolation.While your lungs deliver oxygen to your blood, it takes blood vessels and a heart to move that oxygen to the muscle cells in your foot.
3 Organ SystemsA group of two or more different organs that work together to perform one or more specific functions in the body.

8 Nervous System made up of the brain, spinal cord, and nerves sends and receives nerve messages throughout the bodycontrols behavior, movement, and processes such as digestion and circulation
9 Digestive Systemmade up of the mouth, salivary glands, esophogus, stomach, liver, gall bladder, pancreas, small and large intestines, and the colonbreaks food down so that nutrients can be absorbed by the blood and transported to all cells
10 Excretory System made up of the kidneys, ureters, bladder, and urethra filters the blood and removes liquid waste and extra water from the body
