6 2. NoseAir enters your body at the nostrils or NASAL CAVITY in your nose.
7 3. Nasal Cavity’s Function In the nose, air is moistened by the mucus.It is warmed by contact with the blood.It is filtered or cleaned by mucus and hairs trapping dust particles.
8 4. Pharynx Another name: The voice box Passageway force air into the lungs and food into esophagusImportant in vocalization
9 4. Trachea Another name:The windpipe Passageway for air to move to and from the respiratory systemRings of cartilage hold it open
10 5. Bronchi and Bronchioles The trachea branches into two tubes called Bronchi to carry air into the lungs.The Bronchi break up into smaller branches called bronchioles.
11 6. Lungs Main organs of the Respiratory System Where gas exchange occurs
12 7. Alveoli Tiny sacs that allow for gas exchange. This is where the respiratory system joins the circulatory system.
13 8. Gas Exchangeoxygen changes place with carbon dioxide and water.
14 9. Diaphragm Large dome-shaped muscle When the diaphragm moves it causes you to inhale and exhale.Inhale – breathe inExhale – breathe out
15 10. Function Moves oxygen into the body Removes carbon dioxide, water and wastes
16 11. Respirationthe process by which oxygen and glucose (sugar) undergo a complex series of chemical reactions inside cells. This is basically how cells use oxygen to make energy from the glucose. The waste product from these reactions is water and carbon dioxide.
17 12. Maintaining Homeostasis Cells use the oxygen to make energy to perform their jobs.If the cells don’t have oxygen they can’t do their jobs so tissues and organs begin to die.
