A
Anything
B
Is a tract that connects our lungs to the outside
C
Is a part of our lungs
D

Explanation: 

Detailed explanation-1: -Your trachea is divided into two air passages called bronchial tubes. One bronchial tube leads to your left lung, the other to your right lung. For your lungs to perform their best, your airways need to be open when you inhale and when you exhale.

Detailed explanation-2: -The nose. The nose is the only part of the respiratory system that is visible externally and is the route for air entry into the respiratory system. Air is drawn in via the nostrils or external nares and enters the large nasal cavity, which is divided into two by the nasal septum.

Detailed explanation-3: -The TRACHEA (windpipe) is the passage leading from your pharynx to the lungs. The RIBS are bones supporting and protecting your chest cavity. They move a small amount and help the lungs to expand and contract. The trachea divides into the two main BRONCHI (tubes), one for each lung.

Detailed explanation-4: -The respiratory system helps in breathing (also known as pulmonary ventilation.) The air inhaled through the nose moves through the pharynx, larynx, trachea and into the lungs. The air is exhaled back through the same pathway. Changes in the volume and pressure in the lungs aid in pulmonary ventilation.
