Describe how pneumonia can affect gas exchange?

Answer 1

because the gravity is sampak to the moon and it creates tb that destroy lungs

above is crap and who ever wrote it sucks

When someone has Pneumonia, fluid begins to fill up around the tiny alveoli in the lungs (they look like grapes). Its the alveoli job to supply the blood with oxygen and exhale carbon-dioxide from the body. When you have fluid on the lungs, oxygen cant supply the body with the adequate amount of oxygen. The wheezing you hear is the air trying to get through the fluids. Also carbon dioxide has an issue leaving the body as well. Over time you will find that people retain carbon dioxide and end up with conditions such as COPD.

Answer 2

In emphysema the walls of the alveolar break down and this results in reduced surface area for gas exchange therefore less amount of air is replenished in the lungs.
In pneumonia, tissue fluid accumulate in the alveolar and once again the surface area for gas exchange is reduced.

Answer 3

A decrease in surface area after a pneumothorax is responsible for decrease gas exchange. One of the amazing things about our body is its need to increase surface area (intestine's, lungs etc)

More surface area allows for more exchange of o2 and co2.

Answer 4

In health, small blood vessels surround tiny air sacs called alveoli. Alveoli are hollow grape-like structures where gas exchange occurs. In emphysema, the air sacs collapse, causing less surface area for gas exchange. So CO2 remains higher in the bloodstream, and since hemoglobin is still carrying CO2 molecules, they cannot trade and get fresh O2 molecules.

Answer 5

Emphysema impedes and reduces gas exchange. RBC's hemoglobin carrying CO2 back to the lungs cannot drop it off. Because C02 molecules stay attached to the Hgb (when they should transport off), that means there are fewer spots to pick up 02 molecules on Hgb. So CO2 increases in circulating blood.
