  13. Nervous System Respiratory System Circulatory System Digestive System Reproductive System Urinary System

  14. Digestive System Mouth: Where food enters Teeth: Grind down the food to small particles Thyroid Gland: Gland near the esophagus that produces hormones related to eating Esophagus: Long tube that pushes food down to stomach Stomach: Stomach acids and enzymes break down the food Pancreas: Connected to stomach that excretes hormones to the body Liver: Rids toxins from your food Gall Bladder: Stores bile that the liver uses Small Intestine: Enzymes take all of the nutrients from the food and transport them back to the body Large Intestine: Removes all moisture from the food leaving only waste Rectum: Where waste is stored Anus: Valve that expels waste

  15. Respiratory System Nasal Cavity: Where air enters Pharynx: Divides the trachea (wind pipe) and esophagus (food pipe) Larynx: Voice Box Trachea: Wind Pipe (air travels to lungs) Lungs: Transports blood and oxygen throughout the body Bronchi: Two tubes connecting to each lung Bronchioles: Sacks in the lungs that get air to all parts of the lungs Diaphgram: Band of muscles under lungs that help deep breathing

  16. Urinary System Kidneys: Organs that filter the blood and remove waste from the urine Bladder: Temporary storage for the urine Ureter: Small tube that carries urine from the kidney to the bladder Urethra: Organ that expels urine from the body

Reproductive System Ovaries: Sacks that contain the female eggs Fallopian Tubes: Narrow tubes where the egg travels to the uterus Uterus: The cavity where a fetus grows Cervix: The opening from the vagina to the uterus Vagina: The passageway from the vulva to the cervix Bladder: Where urine is contained Prostate: The main nerve of the male system that produces sperm Penis: The male organ that transports urine and sperm Testes: Small sacs where sperm are stored before ejaculation

  18. Circulatory System Heart: Organ that is the central stations for transportation of blood and oxygen throughout body Aorta: major blood vessel leading straight to the heart Arteries: Major blood vessels that transport blood throughout the body

  19. Nervous System Brain: Center of the nervous system. Controls all of the other systems in the body. Cerebellum: Above the brainstem, controls movement, balance, equillibrium and muscles Motor Cortex: Part in the cerebrum (from of brain) that controls all movements Nerves: Bundles of cables throughout the body that control feeling and responses Spinal Cord: Long cord of nerves and bones that is connected to the brain that controls movement
