  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?

  A Master Stephen Co , Alternative & Complementary Medicine, answered

  The diaphragm is a disk-shaped layer of muscle that bisects your chest cavity laterally. Attached to the bottom of the ribs and stretching backward and slightly downward to the lumbar vertebrae, it is quite flexible, but it is also one of the body’s toughest and strongest muscles. The diaphragm acts as a divider between your cardiopulmonary system and your digestive system: it’s the floor for your heart and lungs, and the roof for your stomach, intestines, spleen, liver, pancreas, and kidneys. There’s not a lot of room in your chest and abdomen; your organs are packed tightly. Thus when your diaphragm moves, it also moves your internal organs, giving them an internal massage. This is a good thing! Diaphragmatic movement stimulates the flow of blood and lymph into, through, and out of these organs in the chest and abdominal cavities.

• QWhat are the benefits of deep nasal breathing?

  A

  

  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 carbon dioxide?

  A Reston Hospital Center answered

  Carbon dioxide is a colorless, odorless gas. It is a waste product made by the body. Carbon dioxide travels in the blood from the body's tissues to the lungs. Breathing out clears carbon dioxide from the lungs.

• 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.
