Question
Chapter 4.3, Problem 2BC
Summary Introduction
To analyze:
The affect of the ratio of surface area/volume on the shape of structures involved in gas exchange.
Introduction:
The respiratory system in human beings is responsible for the gaseous exchange of carbon dioxide and oxygen with the body cells and the environment. The cells of the respiratory system are ciliated in the upper respiratory tract to remove the dust and the foreign antigens from entering lower respiratory tract.

The time it takes for blood to pass through the capillaries of a pulmonary alveolus typically is less than 0.3 seconds. During this time, what will occur?
Select one:
a.
The blood plasma will be cleansed of its entire CO2 content and will be saturated with O2.
b.
An enzyme will catalyze the conversion of oxyhemoglobin to carboaminohemoglobin.
c.
Blood will pick up CO2 and O2 will be released to the alveolus.
d.
Blood will pick up O2 and CO2 will be released to the alveolus.I think this is C or D tell me the answer and why
Explain why the gas values from the alveolar air to the blood change during pulmonary gas exchange.
For example:
Alveolar air for CO2 has a value of 40mmHg then when entering the blood shifts to 45mmHg. Why does this occur?
I tried to calculate this by using Dalton’s law but I’m not
Understanding.
Fig. 2.1 shows photomicrographs of lung tissue at the same magnification. One shows healthylung tissue and the other shows lung tissue from a person with COPD.
Line AB shows the diameter of one healthy alveolus. Line CD shows the diameter of an area oflung where the alveoli have been destroyed. The real diameter of healthy alveolus is 200 µm.If line AB in the picture is 2 cm, calculate the magnification of the picture......
