Inspiration

Q.

Respiration involves 5 basic steps and the correct order of them is

1. Pulmonary ventilation $\Rightarrow$ External respiration $\Rightarrow$ Transport of gases $\Rightarrow$ Internal respiration $\Rightarrow$ Cellular respiration

2. Internal respiration $\Rightarrow$ Cellular respiration $\Rightarrow$ Pulmonary ventilation $\Rightarrow$ External respiration $\Rightarrow$ Transport of gases

3. Internal respiration $\Rightarrow$ Cellular respiration $\Rightarrow$ External respiration $\Rightarrow$ Transport of gases $\Rightarrow$ Pulmonary ventilation

4. External respiration $\Rightarrow$ Transport of gases $\Rightarrow$ Internal respiration $\Rightarrow$ Cellular respiration $\Rightarrow$ Pulmonary ventilation

Q.
