Transcript of Respiratory System
Sends air throughout the body
Connect Trachea to Lungs Bronchial Tubes 10-14 inches long
Weight about 2 1/2 pounds
In chest, held to thorax wall
allows person to breath, gas exchange
Cells in lungs clear airways Lungs Alveoli Diaphragm Highest "Sneeze Speed": 165 mph
Lungs surface area: tennis Court
Hiccups: spasm of the Diaphragm Fun Facts!!! helps prevent damage to respiratory system
below nasal bone and above the mouth
divided into 2 segments:
Respiratory- directs air to other side of nose
Olfactory- control sense of smell
length-2.5 mm across Also known as voice box makes your voice cartilages make an open/ patent airway Epiglottis routes food to stomach Epiglottis also routes air to stomach it is 2 inch. high 40 times surface area of skin
Look like tiny air sacs
Have one single thick cell
Located in the lungs
Folded; gas can pass through easier
Walls are thick; gas diffuses better
Has a thin layer of moisture slightly resembles a butterfly Located in the throat Separated into 3 parts:
Nasopharnx- back of skull to mouth's surface
Oropharynx- separates path of food and air
Larynopharynx- connects to esophagus
length-16.9cm in males, 14.1 in females
carries food to esophagus & air to windpipe Helpful for breathing and respiration
Dome like structure
Lungs and heart rest on it
Functions as main respiratory structure
Contracts/Expands when you exhale/inhale Brainpop http://www.brainpop.com/health/bodysystems/respiratorysystem/ tube that connects mouth to air shape is tube splitting in half located between lungs and under larynx Link Between Organs 4 inches long Link Between Systems THE END!!!!!!! Nasal cavity brings air into body
Air travels down Phraynx and Layrnx
Airways from larynx to Bronchial Tubes
Bronchial Tubes connect to Lungs
Alveoli are in lungs
Lungs connect to diaphragm
Trachea is in the pharynx Works Cited
