What is the atmospheric pressure at sea level?
760 mmHg
What is the relationship between the length of Column A and the force?
The longer the column, the bigger the force
What is the indication of the longer Column A?
The pressure is bigger
What is the pressure in the atmosphere related to?
The weight of the air
What is the inference that can be made from the comparison of Column A and Column B?
Column A has a bigger force
At what altitude does the atmospheric pressure decrease by 50%?
Every 5500m
What is the approximate atmospheric pressure at the top of Mount Everest?
234mmHg
What is the effect of high altitude on the human body?
Hypoxia
At what height is Mount Everest above sea level?
8888m

What part of the respiratory system does obstruction always affect?
Conducting zone
Where does restriction always occur in the respiratory system?
Respiratory zone
What is the effect on Resistance (R) when an obstruction occurs in the airways?
It increases Resistance (R)
What is the primary difference between obstruction and restriction in the respiratory system?
Obstruction occurs in the conducting zone, while restriction occurs in the respiratory zone
What happens to the airways when an obstruction occurs?
They become narrower
Why is it important to open the airways when an obstruction occurs?
To reduce Resistance (R)
In which zone of the respiratory system does restriction occur?
Where gas exchange occurs
What is the relationship between obstruction and the conducting zone?
Obstruction always occurs in the conducting zone
Why do we only need to know PO2 and PCO2?
Because they are always affected
What zone is affected when an obstruction occurs in the airways?
Conducting zone
What is the temperature that affects our physiological processes?
37° Celsius
What is the value of PH2O in RS at a physiological temperature?
47mmHg
What would be the consequence of not opening the airways when an obstruction occurs?
It would increase Resistance (R)
What is the significance of 37° Celsius in human physiology?
It is the normal body temperature
Why is it important to know the values of PO2 and PCO2?
To understand the functioning of the respiratory system
Understand the relationship between pressure and force in physics. Learn how to determine the pressure based on the force applied. Quiz your knowledge on the concepts of pressure and force.
