Match the parts of respiratory system given in column I with their respective functions in column II and choose the correct option given below.
| Column I | Column II |
|---|---|
| A. Mesethmoid cartilage | I. separates thoracic and abdominal cavities |
| B. 'C' shaped incomplete cartilaginous rings | II. divides nasal cavity into right and left chambers |
| C. Epiglottis | III. prevents entry of food into trachea |
| D. Diaphragm | IV. prevents collapsing of trachea |
Options
- AA-II, B-III, C-IV, D-I
- BA-II, B-IV, C-III, D-I
- CA-I, B-III, C-II, D-IV
- DA-III, B-IV, C-I, D-II
Correct answer
B. A-II, B-IV, C-III, D-I
Step-by-step solution
Mesethmoid cartilage forms the nasal septum, which divides the nasal cavity into right and left chambers. Thus, A matches with II.
'C' shaped incomplete cartilaginous rings are present in the trachea to prevent it from collapsing during inspiration. Thus, B matches with IV.
Epiglottis is a cartilaginous flap that covers the glottis and prevents the entry of food into the trachea during swallowing. Thus, C matches with III.
Diaphragm is a dome-shaped muscular structure that separates the thoracic cavity from the abdominal cavity. Thus, D matches with I.
The correct matching is A-II, B-IV, C-III, D-I.
Answer: A-II, B-IV, C-III, D-I
