air
|
about 79% nitrogen, 20% oxygen, and 1% other gases
|
|
air quality index
|
-is an index used to report daily air quality for five major air pollutants: ground level ozone, particulate matter, carbon monoxide, sulfur dioxide, and nitrogen dioxide
-ranges from 0-500 -the higher the AQI the more polluted the air -#s above 100 are considered to be unhealthy |
|
alveoli (air sacs)
|
-lungs made up of millions
-located at the end of the bronchioles -lots of capillaries where the exchange of oxygen and carbon dioxide take place |
|
bronchi
|
-the bottom of the trachea splits into to branches called bronchi
-each bronchi goes to a lung and delivers air to it |
|
bronchitis
|
-when a microorganism such as a virus causes an infection off the trachea
|
|
bronchiole
|
-each bronchus branches into several smaller tubes that are connected to the alveoli
|
|
cellular respiration
|
- in a cell, when sugar and oxygen combine to produce energy, carbon dioxide is also produced
|
|
carbon monoxide
|
-poisonous gas in cigarette smoke
-attaches to the hemoglobin and the oxygen cannot be carried by red blood cells -chemical symbol is CO |
|
chemical reaction
|
sugar + oxygen --> energy + carbon dioxide+ water is the CHEMICAL REACTION for cellular respiration
|
|
trachea
|
- starts at the top of your throat and is in front of the esophagus
-connects with the lungs with your pharynx and allows air to enter your lungs |
|
cilia
|
-line the trachea and bronchi
-very fine hair like structures -wave back and forth moving mucus, along with dust and other particles up and out of the respiratory system |
|
diaphragm
|
-a sheet of muscle located under the lungs
-contracts to let air in lungs and relaxes to let air out |
|
emphysema
|
-can occur when the alveoli are damaged by smoke
-breathing becomes difficult |
|
larynx
|
-the firm structure at the top of the trachea
-called voice box or adams apple -contains vocal cords -when air passes through vocal cords, they vibrate, producing sound |
|
ribs
|
-muscles that are located in between them contract and relax to help move air in and out of the lungs
|
|
tars
|
-sticky brown substances found in cigarettes
-they collect in smokers lungs, irritate cells, and prevent oxygen and carbon dioxide from being exchanged |
|
nicotine
|
-the addictive chemical found in tobacco
-affects the nervous system and smokers crave the feeling they get when they smoke |
|
sulfur dioxide
|
-a gas found in polluted air
-irritates eyes and nose -damages lungs -chemical symbol is SO2 |
|
nitrogen dioxide
|
-a gas found in polluted air
-irritates eyes and nose -can cause bronchitis and pneumonia |
|
pollution
|
-air that is dirty enough to cause health issues
|
|
respiratory system
|
-major parts are the nose, mouth, trachea, and lungs
-help deliver oxygen and other gasses to the blood and remove CO2 and other waste from the blood |
|
respiratory system
|
-major parts are the nose, mouth, trachea, and lungs
-help deliver oxygen and other gasses to the blood and remove CO |
|
mucous membrane
|
-nose is lined with it
-moistens the air to prevent lung tissue from dying out |
|
pneumonia
|
-an infection in the lungs
-can be caused by microbes like bacteria and viruses, or by irritation from particles or gasses -symptoms may be a painful cough and fever -primary result is a buildup of fluids in one or both lungs |
|
pharynx
|
where your nasal cavity and mouth join
|
|
ozone
|
-is formed when nitrogen oxide is exposed to sun
-chemical symbol is o3 -levels are highest at daytime and cause lung and eye irritation -damages plants and manufactured materials such as rubber |
|
solid suspendid particles
|
-the dust, smoke, soot, ash and pollen in the air
|
