A lot.
The lungs contain approximately 23 generations of airways, starting from the trachea and branching into progressively smaller bronchi and bronchioles. In total, there are about 300,000 to 500,000 individual airways, which include both the large bronchi and the smaller terminal and respiratory bronchioles. These airways facilitate the movement of air in and out of the lungs, leading to the alveoli where gas exchange occurs.
On average, there are approximately 1500 miles of airways in an adult human.
Oxygen of course(:and many vital nutirents
About 1057.34 kilometres.
About 334.74 kilometres.
67,592.448 kilometres.
2.012 kilometres
13.0035 kilometres.
Kilometres and kilometres are the same measurement. Therefore, 500 kilometres is equal to 500 kilometres.
Kilometres and kilometres are the same unit of measurement. Therefore, 0.09 kilometres is equal to 0.09 kilometres.
I think Jet Airways have 97 Aircraft
Trachea divides in 2 bronchi which conducte air into the lungs (inside the lungs each bronchi divides in many smaller branchs only studied in college)
