Why copd patient cannot apply oxygen more than 4 liter per minute?
because elasticity of alveoli is diminished in patient with COPD therefore administering more than 4liters/minute will collapse alveoli and patient may die.
Explain the effects of the loss of elasticity in the gaseous exchange system of a person with emphysema?
People with emphysema will be... 1. Short of breath and have to breath in and out alot more than a healthy person, because there tidal volume has decreased so cannot hold as much gas. 2.The surface area of the alveoli is reduced. 3.The reduced surface area of the alveoli means that they can sometimes burst.
Importance of elasticity of demand?
It is important because if a company doesn't understand their product's elasticity of demand, they are screwed!
Why the price elasticity of salt is low and price elasticity of Toyota car is high?
The price elasticity of salt is lower than that of the Toyota car because by changing the unit of measurement of salt leaves the elasticity value the same.
How does partial pressure affect the movement of oxygen from the alveoli to the blood?
Partial pressure affects the movement of oxygen from the alveoli to the blood because it is the main driving force for oxygen movement in the lungs.Oxygen passes from the air to the fluid within the alveoli, into the cell of the alveoli.
Why oxygen diffuses from the alveoli into the blood?
Oxygen diffuses from the alveoli into the blood because of a concentration gradient. The partial pressure of oxygen in the alveoli is higher than in the blood, so oxygen moves across the thin membrane of the alveoli into the blood to reach equilibrium.
How does substitutes affect elasticity?
Because elasticity means when the demand is changing. a subsitute consumer in choice of theory. the substiture affects elasticity is it changes over time. substitute is choice and elasticity is demand. put those together and you have a fair deal with your money.

Where in the lungs does gas exchange happen?
AlveoliGaseous exchange takes place in the alveoli of the lung
What happens to the alveoli?
Alveoli are the tiny sacs in the lungs that are the powerhouses of the respiratory system. That is where oxygen-spent blood gives up its carbon dioxide and becomes re-charged with oxygen. Lung alveoli are the ends of the respiratory tree, branching from either alveolar sacs or alveolar ducts, which like alveoli are both sites of gas exchange with the blood as well. Alveoli are particular to mammalian lungs.
How does 300 million alveoli help gaseous exchange?
because it does
Are the alveoli distal or proximal to the bronchi?
The alveoli and bronchi are both parts of the respiratory tree. The main parts of this structure, in the order of air passing through during inspiration are: trachea, bronchi, bronchioles, and alveoli. The alveoli are distal to the bronchi, because they are farther away from the center of the body then the bronchi.
