During ordinary breathing, each breath lets out and replaces about of the air in the lungs The new air mixes with the old air in the lungs A person breathing quietly inhales and exhales about one pint of air at each breath This amount, called tidal air, is enough for ordinary body functioning A person who is exercising can inhale about four quarts of air in each breath This is known as the vital capacity Breathing is regulated by the brain A group of cells in the biain form the respiratory centdT, which is extremely sensitive to carbon dioxide When there is a slight increase in carbon dioxide in (he blood, the center speeds up the impulses it sends to the muscles of respiration This causes faster brea thing When the amount of carbon dioxide returns to normal, breathing also becomes normal iy Auj5 PYSCAllK LUCKY Andy sends the Star Wais Question and Answer Book About Space to Frank Har desty, 10, Marion, Ohio, for his question ?

Ryan Voi unaee airfield By For a person to breathe his chest must expand The lungs fill the chest cavity completely, no matter how large it is So when the chest expands, the lungs do also Expansion lowers the air pressure inside the lungs, creating a slight vacuum that pulls air in from the atmosphere To do this, the diaphragm contracts, pulling its dome downward This provides more room in the chest cavity As the diaphragm contracts, the muscles surrounding the ribs also contract The ribs move upward and outward, making the chest cavity expand frontward in, Jim Davix when the process of inspiration is reversed The muscles act to force out air, just as it is forced out when a bellows is closed. First, the diaghragm relaxes and resumes its dome shape, reducing the space of the chest Then the rib muscles relax, lowering the ribs to make the chest cavity smaller These combined actions squeeze air out of the lungs Exchange of Gases , Breathing is one form of respiration, called ex- ternal respiration The exchange of gases between the blood and other tissues in the body is called interna! respiration Internal respiration is also sometimes called tissue I OUOW-L- A At HOMZ CIVIH& IN ' (, IS WAr&f IN ' avep- - THEfP WASHIH&TCH y y Funky M inkerlM-a- rT HOW t TF DUAL n fY, ? 4r SOOOl.
