Q.Select the correct sequence of events that occur during Human Respiration:
a
Air enters lungs $\rightarrow$ Diaphragm contracts and moves down $\rightarrow$ Volume of chest cavity increases $\rightarrow$ Pressure decreases
b
Diaphragm contracts and moves down $\rightarrow$ Volume of chest cavity increases $\rightarrow$ Pressure decreases $\rightarrow$ Air rushes into the lungs
c
Pressure decreases $\rightarrow$ Diaphragm relaxes $\rightarrow$ Volume decreases $\rightarrow$ Air rushes into the lungs
d
Volume of chest cavity increases $\rightarrow$ Pressure increases $\rightarrow$ Diaphragm contracts $\rightarrow$ Air exits lungs
Correct Answer: Option B
The correct solution involves applying the fundamental concept to derive the final value step by step...
