Lung
* Most lungs absorb oxygen
  - allow air
* Most lungs are near hearts
  - supported by backbones
  - bring oxygen
* Most lungs cause exposure inhalation
  - consist of lobes
* Most lungs contain alveoluses
  - muscles
  - tissue
* Most lungs excrete carbon dioxide
* Most lungs expel carbon dioxide
  - fluid
  - vapor
  - water vapor
  - fill up with air
* Most lungs get air
  - trap air
* Most lungs have air sacs
  - airways
  - bronchioles
  - capacity
  - effects
  - functions
* Most lungs have large air capacity
  - pronounce effects
  - respiratory bronchioles
  - rigid walls
* Most lungs make crackle sound
* Most lungs penetrate alveoluses
  - pulmonary alveoluses
  - produce substances
  - pump air
  - push air
  - receive air
* Most lungs remove carbon dioxide
  - gases
  - harmful gases
* Most lungs serve essential functions
* Some lungs cause problems
  - respiratory problems
  - collect urine
* Some lungs eliminate acid
  - carbonic acid
  - fill cavities
* Some lungs fill up with fluid
  - with blood
* Some lungs have fluid
  - plates
  - rooms
  - strong tendons
  - tiny tubes
  - valves
* Some lungs help mucuses
  - respiratory mucuses
  - move air
  - penetrate skeletons
  - remove oxygen
  - respond to actions
* act as reservoirs of carbohydrates needed for the organism's energy.
* also have large surface areas for gas exchange.
* appear in amphibians developing as outpocketings from the ventral side of the pharynx.
* are able to expand and contract due to a system of elastic fibers that make up their tissues
  - all squishy and moist
  - basically inverted gills
  - blind sacs, unlike the open systems of fish gills
  - clear and the heart shows a regular rate and rhythm with no murmurs, rubs, or gallops
* are clear to auscultation and the heart has a regular rate and rhythm with no murmurs
  - bilaterally
  - clear, the heart has a regular rate and rhythm
  - dark red, swollen, and have minute yellow foci on the pleural surface
  - delicate organs and vulnerable to a range of illnesses
  - divided into spongy, connected chambers
  - edematous
  - especially dependent on vitamin C for protection
  - found commonly in amphibians, reptiles birds and mammals
  - higher up
  - internal organs
  - large and, together with the heart, virtually fill the entire thoracic cavity
  - like sponges, with millions of tiny air sacs for transferring oxygen
  - major organs that bring much needed oxygen into our blood stream
  - mature
  - ozone's primary target
* are part of bodies
  - human bodies
  - respiratory systems
  - positioned along the back and they keep dugong in horizontal position during swimming
  - present but greatly reduced in some species
  - sacks of tissue located just below the rib cage and above the diaphragm
  - small in size and supplemented by air sacs which reduce the body weight
  - small, spongy but non-elastic
  - solid, respiratory surface is offered by the inner lining of parabronchi
* are spongy in structure, rather than sac-like
  - structures made up of special cells called as alveoli
* are the first to decay
  - only organ in the body light enough to float on water
  - primary site for most cancer metastasis
  - respiratory organs in human beings
* are usually dark and wet
  - very compliant, largely due to the low surface tension of the liquid lining the lungs
* become cleaner and stronger and are better able to resist infection
  - extremely damaged by mineral dust over time
* begin to develop
  - increase production of surfactant to keep alveoli open
* biopsy in rheumatoid lung disease
  - the diagnosis of the pneumoconioses
* breathe easily and safely in the unpolluted air.
* burn, particularly after long shifts.
* ca ncer is the leading cause of cancer death in the United States.
* can also help in water.
* constitute the most different route of drug elimination.
  - internal respiratory surfaces shaped as a cavity or sac
* excretel carbon dioxide out of the body.
* expand as they fill with air.
* facilitate exchanges.
* facts Many smokers die each year from debilitating lung conditions other than lung cancer.
  - with amniotic fluid and fetus begins breathing motions
* force air.
* have a complex series of airways that range from large tubes to small branches
  - much lower density than solid organs as heart or liver
  - cardiac impression where heart sits between the lungs
  - evidence
  - input
  - sections or lobes
* help in the elimination or release of carbon dioxide from the body.
* includes alveoluses
  - corpi
* increase their ability to handle mucus, reduce infection and clean themselves.
* lie within a sealed-off thoracic cavity.
* lose elasticity
  - some elasticity, so ventilation is reduced
* make a significant contribution to removing waste heat from the body
* probably primitive for bony fishes, at least.
* provide a mechanism for oxygen to access blood
  - membrane for gaseous exchange with blood
  - sheltered moist environment for gasses to dissolve
* rattle with fluid.
* recoil due to elastic tissue within.
* replace gills and other organs.
* scarring can result from toxins, burns, or a number of diseases and conditions, such as lupus.
* sounds clear in all lung fields
  - that are dry and harsh often accompany upper respiratory tract infections
* take in oxygen and remove carbon dioxide from the blood
  - for the combustion of food, and they eliminate the carbon dioxide produced
  - oxygen from the air and send carbon dioxide out through the air
* tend to be somewhat fragile compared with other organs.
* try to neutralize acid by the changing respiration rate and gas exchange.
* work by negative pressure in reptiles, in contrast to amphibians.
