The respiratory system in humans begins with nostrils and ends with alveoli
Explanation:
Respiratory system consists broadly of two regions: conducting region and respiratory region. From the nostril upto the terminal bronchioles constitute the conducting region whereas the region from the respiratory bronchiole (first division of terminal bronchiole) upto the alveoli constitute the respiratory zone.
