Sure the alveoli are the site of gas exchange.  What some of the answerers don't know is that alveoli are also associated with the alveolar duct and respiratory bronchiole.\n\nThe term "terminal bronchiole" is kind of a misnomer because they are not the last bronchiole;  just the last purely conducting bronchiole.  They diverge into respiratory bronchioles which are part conducting, and part gas exchange (because of their interspersed attached alveoli).  These diverge into alveolar ducts and alveoli which are purely gas exchange.

The respiratory system is how you breath in and out. In fact, any organism that participates in gas exchange has a respiratory system. In humans and other mammals, the respiratory system consists of the airways, the lungs, and the respiratory muscles that mediate the movement of air into and out of the body.

Mucus - The respiratory tract, from nasal cavities to the smallest bronchi, is lined by a layer of sticky mucus. Particles (such as dust and bacteria) which hit the side wall of the tract are trapped in this mucus. \nCilia - found on the epithelial cells move the mucous continually up or down the tract towards the nose and mouth. \nThe mucus and its trapped particles are then swallowed, taking them to the sterilising vat of the stomach.\nLarynx - The entry of food and drink into the larynx is prevented by the structure of the larynx and by the complicated act of swallowing. The larynx is protected by three pairs of folds which close off the airway, preventing food getting into the lungs, which would lead to choking

there are many diseases that can be obstructive airway diseases.. cbabe is the acronym for the diseases, bronchitis, cystic fibrosis, asthma, emphysema are copd diseases. inside your lungs there are little pockets called aveoli and for gas exchanges these aveoli fill with the air you breath and if they are damaged from disease there will be prblems with airway exchange. with obstructive disease the aveoli are streched out of shape and not reparable. this causes airway trapping , basicly the person breathes in air and because the aveoli are all streched out the air gets traped inside the lungs. \nthat is obstructive airway, then you also have the other problelms associated with the actual disease that you have,. example with asthma you have increased mucous production in the airways, the airways constrict during an ashtma attack and you haveinflamation in the lungs.\nthey need to do pulmonary function test, and more evaluations to find out what kind of obstructive disease she has... i hope everything works out for her

The process is called intubation, and the tube is called an endotracheal tube, or ET tube for short.\n\nIt does depend on the type of operation you have, and what type of anestetic is used. Normally, if you are under "general  anestetic" you are intubated.\n\nIntubation involves the insertion of the ET tube between the vocal chords, and into the trachea. The ET tube has a hole at each end, and the end of the tube that resides in the trachea has an inflatable balloon that helps keep the tube in the proper place. \n\nOnce completed, intubation creates a "patent airway" which means that the air & oxygen is getting directly to the lungs.

inhalation is breathing in, exhalation is breathing out

Insects exchange oxygen and carbon dioxide between their tissues and the air by a system of air-filled tubes called tracheae.  Tracheae open to the outside through small holes called spiracles.  Among the smaller or less active insects, gas exchange though the tracheal system is by simple diffusion.

ALVEOLI:\n The alveoli are the final branchings of the respiratory tree and perform gas exchange for the lung. The thin gas-blood barrier between the alveolar space and the pulmonary capillaries allows for rapid gas exchange. Oxygen and carbon dioxide diffuses through the alveolar epithelium and the capillary endothelium.\n\nThere are two types of alveolar epithelial cells. Type I cells thinly line the alveolar walls. Type II cells produce surfactant - a lubricant that reduces surface tension. \n\nSURFACTANT:\n Surfactant is any substance that acts to alter surface tensions, such as those in the lungs. This substance reduces the surface tension within the alveoli, preventing them from collapsing.\n\nInfant Respiratory Distress Syndrome is caused by a lack of pulmonary surfactant. The alveoli collapse and prevent the infant from breathing properly.

respiration..\n\nco2 is given off, it goes through our blood stream, reabsorbed by the alveoli, switched out with o2 by respiration

The alveoli spread into branches called arbor vitae.\nthe alveoli are present in your lungs and help in exchange of gases(oxygen and carbon di oxide)

Internal Respiration is the exchange of gases between tissues and the blood cells. External Respiration is the exchange of gases between the blood cells and the lungs.\n\nIf you want more information, you can do a quick search on the net, or email me and I'll dig out my old college books and notes.\n\nHope that helps.

Cockroaches, like all insects, breathe through a system of tubes called tracheae, a word similar to the name of the tube leading to our lungs. The tracheae of insects are attached to the spiracles which are small valved openings on the side of each body segment, excluding the head.  Thus the cockroach can breathe without its head!  The valves open when the CO2 level in the insect rises to an unacceptable level; then the CO2 diffuses out of the tracheae to the outside and fresh oxygen diffuses in. The tracheal system brings the air directly to cells because they branch continually like a tree until their finest divisions tracheoles are associated with each cell allowing gaseous oxygen to disolve in the cytoplasm lying across the fine cuticle lining of the tracheole. CO2 diffuses out of the cell into the tracheole. \n\nMost insects do not have muscular lungs and thus do not actively breathe in the vertebrate lung manner. However in some very large insects the diffusion process may not be sufficient to provide oxygen at the necessary rate and body musculature may contract rhythmically to forceably move air out and in the spiracles and one can actually call this breathing. This might be associated with such activities as the energetic flight of the migratory locust.

Insects do not have lungs.  The larger ones breathe through tubes into their body called spiracles and/or smaller tubes called tracheae.  Very small insects breathe through their skin using the process known as diffusion.

It's the valve in the throat that controls the airway to the lungs.  When you swallow it closes so the food doesn't go into the lungs.  I'm not 100% sure so double check me.

The diaphragm is a muscle separating the thorax, or chest cavity from the abdominal cavity.  It is convex (rounded on top) and when a breath is taken, it flattens out - thereby increasing the space in the chest cavity. (At the same time, the rib cage expands).  When the space in the chest cavity increases, the pressure in the chest cavity decreases in relation to atmospheric pressure....this decrease in pressure is what causes the "breath" to enter the lungs.

The starting substances in respiration are a sugar (usually glucose) and oxygen.  The sugar first goes through glycolysis , which breaks it down into 2 pyruvates, 2 ATP, and  2 NADH. Then the 2 pyruvates go into the Krebs cycle (TCA cycle) and more NADH are made, plus 2 GTP.  Then all of the reducing power enters the electron transport chain where electron are transferred to oxygen to make H2O and ATP at the end of the respiration pathway.  The carbons in the glucose are converted into CO2.

DUE TO CONSTICTION OF BRONCHIOLES,LESS OXYGEN IS SUPPLIED TO BODY\nBUT IT NEEDS MORE SUPPLY SO IT MIGHT LEAD TO BRONCHSPASM
