Q: Based on what you saw on the videos, the Key section in UNO, and what we did in class.

Match the definition with the respiratory system organs.

Hint: You can get help from your UNO book page 161.
- The entrance is through the interior of the nose. Here, air becomes warm and moist, and is where they removes harmful substances. | Nasal Passage
- It is where the digestive and respiratory system meet. Air circulates from the nasal passage to the larynx. The epiglottis is located in this area. to prevent food going to the lungs. | Pharynx
- Also called voice box because is where the vocal cords are located. When air exits, it makes these cords vibrate, which creates sounds that allow us to talk. | Larynx
- It is also called windpipe. This tube consists of a series of cartilage rings that maintain its shape. Farther down, it divides into the two bronchi. | Trachea
- The two tubes enters the lungs, and then branches out into many narrower bronchial tubes | Bronchi
- These tubes get smaller and narrower as they travel through the lungs. They allow the air to reach the whole lung. At the end of the tubes, there are clusters of small sacs They can be as thin as a hair. You have about 30,000 in each lung | bronchiole
- This is the end of the respiratory system. This process is called gas exchange. There are about 600 million inside your lungs. | Alveoli
- The big muscle just under your lungs.. It contracts when you inhale and expands as you exhale. | Diaphragm

Q: The respiratory system is automatic and involuntary.
- True (Correct!!!)
- False (Since your birth, you have been breathing all the time without thinking about it.)
