The alveolar sacs must adhere closely in order for gas exchange to occur. In cases of emphysema, the air sacs are dilated causing less carbon dioxide to escape. Since hemoglobin has 200x the affinity for carbon dioxide over oxygen, carbon dioxide builds up leading to respiratory acidosis. This condition is ideal for growing cancer.

Why does a damaged alveoli result in less gas exchange?
because it keeps all the nitro oxide in.
Why does damage to alveoli result less gaseous exchanges?
Damaged air sacs have a lower amount of air surface. This reduces the amount of gas exchanged because the larger the surface the larger the amount.
What Part of lung damaged or destroyed by emphysema?
Emphysema primarily damages the alveoli, which are the tiny air sacs in the lungs where gas exchange occurs. In this condition, the walls of the alveoli become weakened and lose elasticity, leading to their destruction and the formation of larger, less efficient air spaces. This damage results in reduced surface area for gas exchange, making it difficult for the affected individual to breathe and leading to symptoms like chronic shortness of breath.
How does gas exchange in gills differ from gas exchange in lungs?
Gas exchange in gills occurs in water, where oxygen diffuses from the water into the blood and carbon dioxide diffuses from the blood into the water. This process relies on a countercurrent exchange system, maximizing oxygen absorption. In contrast, gas exchange in lungs occurs in air, where oxygen diffuses from the alveoli into the blood and carbon dioxide moves from the blood into the alveoli to be exhaled. Lungs utilize a tidal flow mechanism, which is less efficient than the continuous flow in gills.
How did the fire extinguisher change your lives today?
less deaths and less damaged buildings
Why does less gas exchange in damage lungs?
less gas exchange damages the lungs because the less Co2 (carbon dioxide) that is let out dameges the body in more ways than explainalbe
Importance of foreign exchange rate?
The foreign exchange rate helps determine the value of money. When the exchange rate is high, then the currency is less valuable.
When particles move to a less concentrated place is called?
When particles move to a less concentrated place, it is called diffusion. This process occurs as particles naturally spread out from areas of higher concentration to areas of lower concentration in an attempt to achieve equilibrium. Diffusion is a passive process and occurs in gases, liquids, and even solids. It plays a crucial role in various biological and physical processes, such as gas exchange in the lungs.
How the fuel consumption will increase with damaged propeller?
A damaged propeller (e.g. with a blade or part of a blade missing) will "move water" less efficiently.
Does crossing over occur in meiosis?
Yes, crossing over occurs during meiosis. It is the process where homologous chromosomes exchange genetic material, increasing genetic variation among offspring. This occurs during prophase I of meiosis.
Explain the concept of income elasticity of demand and how it is calculated?
When you have less income you tend to consume less.
Why is the amount of gas exchanged in a damaged air sac less?
When an air sac is damaged, the surface area available for gas exchange is reduced. Gas exchange occurs across a membrane, and if this membrane is compromised, the efficiency of gas exchange is decreased. Additionally, damage to the air sac can disrupt the diffusion gradient necessary for gas exchange, further limiting the amount of gas exchanged. Overall, a damaged air sac impairs the ability of the respiratory system to effectively exchange gases, leading to a decrease in the amount of gas exchanged.
