9 From the capillaries through the circulation to the capillaries in the organs.
10 The branching of the bronchi and bronchioles that looks like an upside down tree
12 This is hemoglobin without oxygen molecules. Oftentimes deoxy- hemoglobin contains carbon dioxide instead. They are colored purple or blue.
13 The most amount of air that the lungs can hold.
15 red blood cells transport oxygen from the lungs to the cells and transport carbon dioxide from the cells to the lungs.

17 This is hemoglobin containing oxygen molecules. They are colored red.
19 The process converting sugars [glucose] and oxygen into carbon dioxide, water, and energy [ATP].
22 muscles between the ribs that also allow the lungs to expand. This is how your rib cage moves when you breathe.
25 Tiny blood vessels at the end of each alveolus. This is where the oxygen enters the blood stream and where carbon dioxide exits the blood stream.
1 breathing out carbon dioxide and water vapor.
2 This is a little flap that moves to block the windpipe when you are eating.

5 This is one of the products of cellular respiration. This is where the cells obtain the power they need to operate efficiently.
6 the smaller and smaller branching of the bronchi. The plural of this is bronchioles.
7 The air moving from the nasal passage or mouth, to the trachea, through the bronchi. Then it goes through the bronchiole and from there, to the alveoli.
8 The movement from the capillaries in the tissues of the organs to the cells and mitochondria.
11 This is found throughout the respiratory system. Its purpose is to moisten the air that we breathe so it protects the sensitive cells in our lungs from drying out.
14 the voicebox. This is how you make noise when you talk.
18 taking in oxygen
20 The trachea splits into two large tubes, one going to the left lung, and one going to the right lung. The plural of broncchus is bronchi.
21 The protein in the red blood cells that allows oxygen to be transported.
23 Tiny sacs at the end of each bronchiole. This is where oxygen and carbon dioxide are exchanged. The plural of this is alveoli.
24 The area of the body where oxygen is inhaled and carbon dioxide is inhaled and carbon dioxide is exhaled
26 protects your lungs and your heart.
