• QWhat is carbon dioxide?

  2 Answers

  A

  

  A Jumo Health answered

  Carbon dioxide, a waste product, passes from the blood into tiny sacs in the lungs called alveoli. The lungs then get rid of carbon dioxide when people breathe out, or exhale. The more healthy alveoli there are, the easier the air can get in and out.

• QWhat are airways?

  A Jumo Health answered

  Airways are the tubes that carry air into the lungs and back out again. The airways start off big. The biggest one is called the trachea, also known as the windpipe. The trachea then branches off into smaller tubes.

• QWhat is the role of the diaphragm in my body?

  2 Answers

  A

  

  A National Athletic Trainers' Association answered

  When the diaphragm contracts, it flattens out, lowering the pressure in the lungs and allowing air in. When the diaphragm relaxes, it makes a dome shape, increasing the pressure in the lungs and pushing air out. (This answer provided for NATA by the University of Montana Athletic Training Education Program.)

• QWhat are the benefits of deep nasal breathing?

  A Dr. Michael Roizen, MD , Internal Medicine, answered

  Deep nasal breathing isn't just for yoga rooms and massage tables. Dee-ee-ee-ee-ee-ee-ee-p brea-ea-ea-ea-ea-ea-ea-ea-thing helps transport nitric oxide—a very potent lung and blood vessel dilator that resides in your nasal passages—to your lungs. And since it's located in the highest concentration in the back of your nose, deep breathing is also the best way to increase nitric oxide to help your lungs and blood vessels open up better and function more efficiently.
  
  Essentially, taking deep breaths helps your lungs go from 97 percent saturation of oxygen to 100 percent saturation of oxygen, and that little 3 percent can sometimes make a difference in how you feel.
• QWhat is the diaphragm?

  A Pam Grout , Alternative & Complementary Medicine, answered

  The diaphragm is the all-important dome shaped muscle between the stomach and the chest that  automatically moves downward to draw air into the lungs and then moves up to press air out. The diaphragm is an invaluable tool. Once you understand how it works, try to "feel" the diaphragm in your own body.

• QWhat are the major parts of the respiratory system?

  1 Answer

  A

  

  A Columbia University Department of Surgery answered

  The major components of the respiratory system are the bronchi, the larger conducting airways that begin at the end of the trachea and go into the lung; the bronchioles, the more narrow airways that branch from the bronchi; and alveoli, tiny air sacs located at the end of the bronchioles where the exchange of oxygen and carbon dioxide takes place -- the respiratory zone. Blood carries oxygen from the respiratory zone to cells and returns carbon dioxide to the respiratory zone for disposal via exhalation.
