the labelling of the diagram of the respiratory tract ( from above downwards) is given below.
A. Collar
B. Appendage
C. Fin
D. Ligaments
Explanation:
- The respiration takes place due to the presence of the respiratory tract which carries external air from the atmosphere inside the respiratory organ of our body. The surface area of the respiratory organ is greatly increased so as to increase the diffusion of the gases into the body fluid from the alveoli.
- Also the respiratory tract is kept moist and it is filled with ciliated epithelium so that there is tapping of the harmful dust particles and germs
