Breathing is the process that moves air in and out of the lungs or oxygen through other breathing organs such as gills. Aerobic organisms of these types—such as birds, mammals, and reptiles—require oxygen to release energy via respiration, in the form of the metabolism of energy-rich molecules such as glucose. Breathing is only one process that delivers oxygen to where it is needed in the body and removes carbon dioxide. Another important process involves the movement of blood by the circulatory system. Gas exchange occurs in the pulmonary alveoli by passive diffusion of gases between the alveolar gas and the blood in lung capillaries. Once these dissolved gases are in the blood, the heart powers their flow around the body (via the circulatory system). The medical term for normal relaxed breathing is eupnea.

Famous quotes containing the word breathing:
“Mark the babe
Not long accustomed to this breathing world;
One that hath barely learned to shape a smile,
Though yet irrational of soul, to grasp
With tiny fingerto let fall a tear;
And, as the heavy cloud of sleep dissolves,
To stretch his limbs, bemocking, as might seem,
The outward functions of intelligent man.”
—William Wordsworth (17701850)
“On like the wind they hurried, and Morgan rode in advance;
Bright were his eyes like live coals, as he gave me a sideways
And I was just breathing freely, after my choking pain,
When the last one of the troopers suddenly drew his rein.”
—Constance Fenimore Woolson (18401894)
“Of all the words mentioned in language, there is not one that I hate more than the word right. Is it your right that your field prospers? That you dont drop dead this very instant? Are living and breathing your right? As far as I can see, nothing but grace and blessing fill the universe, and these worms talk about right?”
—Franz Grillparzer (17911872)
