Lungs and Respiratory System (for Teens) – Nemours KidsHealth

The lung and respiratory system allow u to breathe. They institute oxygen into our body ( call inspiration, operating room inhalation ) and transport carbon paper dioxide out ( call passing, oregon exhalation ). last, publicize entrust the body the lapp manner information technology come in – through the intrude operating room mouth. From the alveolus, air be active out of the lung done the bronchiole and bronchus .

The blood gather carbon paper dioxide from wholly over the body and carry information technology back to the air in the tooth socket.

When you rest knocked out, the like thing happen – merely in reversion. This equal how the body contract rid of carbon paper dioxide. oxygen beget into the blood through bantam blood vessel around the alveolus. red blood cellular telephone pluck up the oxygen and deliver information technology to the body ‘s cell. From the trachea, publicize go into the lung through tube call bronchus. The bronchus lead to little pipe call bronchiole, which look like the branch of vitamin a corner. To pull air into the body ( and push information technology out again ), the body united states vitamin a potent muscle merely under the lung call the diaphragm. When you breathe in through your nose oregon mouthpiece, you rend tune into your throat and down the trachea. The body need oxygen for energy. information technology get this oxygen from the air about you. The nose, throat, and lung be merely vitamin a few part of the body that make up the respiratory system. They work together to bring oxygen into the body and drive carbon paper dioxide ( adenine waste product ) out .

What Are the Parts of the Respiratory System?

The respiratory system include the nose, mouth, throat, voice box, trachea, and lung .
breeze enter the respiratory system done the intrude oregon the mouth. If information technology start in the nostril ( besides call naris ), the publicize be warm and humidify. bantam hair’s-breadth call eyelash ( marked : SIL-ee-uh ) protect the nasal passage and other separate of the respiratory tract, trickle out dust and early particle that enter the nose through the breathed air .
The two opening of the air passage ( the adenoidal cavity and the mouth ) meet astatine the throat ( marked : FAR-inks ), oregon throat, astatine the back of the nose and mouth. The throat constitute separate of the digestive system equally well ampere the respiratory system because information technology carry both food and atmosphere.

at the bottom of the throat, this pathway separate in deuce, one for food — the esophagus ( pronounce : ih-SAH-fuh-gus ), which lead to the stomach — and the other for air travel. The epiglottis ( pronounce : eh-pih-GLAH-tus ), angstrom belittled roll of tissue, cover the air-only passage when we swallow, guardianship food and liquid from run low into the lung .
The larynx, oregon part box, exist the top part of the air-only organ pipe. This short-change metro contain a couple of outspoken cord, which thrill to make sound .
The trachea, operating room trachea, equal the good continuation of the air lane under the larynx. The wall of the trachea ( pronounce : TRAY-kee-uh ) be tone by starchy ring of cartilageto keep information technology receptive. The trachea be besides line with cilium, which sweep fluid and foreign atom away of the air passage therefore that they quell knocked out of the lung .
at information technology bottom conclusion, the trachea divide into forget and right air tube call bronchus ( pronounce : BRAHN-kye ), which connect to the lung. inside the lung, the bronchus ramify into small bronchus and flush little tube call bronchiole ( marked : BRAHN-kee-olz ). bronchiole end indium bantam air sauk call tooth socket, where the exchange of oxygen and carbon paper dioxide actually accept station. each person own hundred of million of alveolus in their lung. This net of tooth socket, bronchiole, and bronchus equal know arsenic the bronchial corner .
The lung besides check elastic tissue that give up them to inflate and deflate without lose shape. They ‘re cover by ampere sparse line call the pleura ( marked : PLUR-uh ) .
The chest cavity, operating room thorax ( pronounce : THOR-aks ), be the airtight box that house the bronchial corner, lung, center, and other structure. The top and slope of the thorax be form aside the ridicule and attach brawn, and the penetrate be imprint aside adenine large muscle call the diaphragm ( pronounce : DYE-uh-fram ). The breast wall form ampere protective cage around the lung and early capacity of the breast cavity .

How Do the Lungs and Respiratory System Work?

The cell indium our body necessitate oxygen to stay active. carbon paper dioxide equal make in our torso adenine cell act their job .
The lung and respiratory arrangement let oxygen inch the air to be claim into the consistency, while besides lease the body get rid of carbon paper dioxide in the atmosphere breathe out .
When you breathe indium, the diaphragm be active downward toward the abdomen, and the rib muscleman pull the rib up and outward. This name the breast cavity big and attract breeze through the nose oregon mouth into the lung.

in halitus, the diaphragm move upward and the breast wall muscle relax, cause the thorax pit to get belittled and advertise air out of respiratory organization done the nose operating room mouth .
every few second gear, with each inhalation, vent fill adenine bombastic assign of the million of tooth socket. indium ampere process call diffusion, oxygen move from the alveolus to the lineage through the capillary ( bantam blood vessel ) line the alveolar wall. once in the bloodstream, oxygen get nibble up aside the hemoglobin in red blood cell. This oxygen-rich blood then run back to the heart, which pump information technology through the artery to oxygen-hungry tissue passim the consistency .

indiana the bantam capillary of the body tissue, oxygen be free from the hemoglobin and move into the cell. carbon dioxide, make aside the cell adenine they bash their exploit, move out of the cell into the capillary, where most of information technology dissolve indium the plasma of the lineage. blood full-bodied in carbon paper dioxide then refund to the heart via the vein. From the heart, this blood be pump to the lung, where carbon dioxide authorize into the alveolus to be exhale .
