Respiratory system

finished

QuestionAnswer
What is the main function of the respiratory system? set of organs that supplies the body with oxygen(breathing)
Nose and Mouth passages for air; nose lined with cilia tiny hair protections trap dirt and air particles
Trachea tube in throat that takes air to and from lungs (windpipe)
Epiglottis flap of tissue in the back of mouth that covers the trachea to prevent food from entering.
Diaphragm large dome-shaped muscle below the lungs that expands and relaxes to breath
Lungs two large organs that exchanges oxygen and carbon dioxide
Bronchi two tubes that branch from the trachea; one tube leads to each lung
Inhaling your diaphragm moves down and your rib cage expands
Inside the lungs the bronchi divides into smaller passages called bronchial
Exhaling your diaphragm pushes up, and your ribs move in and down forcing air out of the lungs
