Problem 28
Question
Sites of gaseous exchange in lungs are (a) Alveoli (b) Bronchi (c) Bronchioles (d) Pleura
Step-by-Step Solution
Verified Answer
The site of gaseous exchange in lungs are alveoli (option A).
1Step 1: Indicating all parts of the respiratory system
The lungs consist of different structures that include alveoli, bronchi, bronchioles, and pleura.
2Step 2: Understand function of each structure
The function of the bronchi and bronchioles is to direct the flow of air to the alveoli. Alveoli are tiny air sacs where gaseous exchange occurs. The pleura is a protective double-layered membrane surrounding lungs and chest cavity.
3Step 3: Selecting the appropriate structure for gaseous exchange
Based on the functions of each structure, alveoli are the place where oxygen and carbon dioxide are exchanged in the lungs.
