Explanation / Answer

Answer:

1). A). oropharynx, B). Trachea

The major passages and structures of the lower respiratory tract include the windpipe (trachea) and within the lungs, the bronchi, bronchioles, and alveoli. Deep in the lungs, each bronchus divides into secondary and tertiary bronchi, which continue to branch to smaller airways called the bronchioles

2). A). Hairs in the nasal vestibulae

Inside the vestibule are small hairs called vibrissae, which filter dust and other matter that are breathed in.

3). A). External nares

Humans have two external nostrils (anterior nares) and two additional nostrils at the back of the nasal cavity, inside the head (posterior nares, posterior nasal apertures or choanae).

4). E). Pharynx

Pharynx is commonly referred to as the throat. The pharynx is part of both the digestive and respiratory systems. For the digestive system, its muscular walls function in the process of swallowing and it serves as a pathway for the movement of food from the mouth to the esophagus.

5). D). Oropharynx

Oropharynx - serves as a common passageway for food and air. Palatine tonsils lie in the lateral walls of the fauces. Lingual tonsil covers the base of the tongue

6). D). A, B, and C

There are six cartilages, three unpaired and three paired, that support the mammalian larynx and form its skeleton.
