- oropharynx
- larynx.
- nasopharynx
- laryngopharynx
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The trachea or wind pipe is the tube in air breathing vertebrates that conducts air from the throat to bronchi. It is strengthened with incomplete rings of cartilage. It originates from laryngopharynx, the lowermost or interiormost part of the pharynx. Pharynx (throat) is divided into three parts, the nasopharynx (nasal part of the pharynx) which lies behind the nasal cavities, above the soft palate, the oropharynx (oral part of the pharynx) which lies behind the oral cavity (buccal cavity) and the laryngopharynx (laryngeal part of the pharynx).

Breathing and Exchange of Gases
A metabolic process, which is carried out by all living organisms including plants, animals, and humans for the production of energy and to stay alive is Respiration. Except for required anaerobes, every other organism from amoeba to humans needs oxygen for survival. And evolution has reported a number of systems that allows the exchange of gases in organisms.
There are two types of respiration such as;
- Aerobic respiration — to produce energy, it occurs in the presence of oxygen
- Anaerobic respiration — to produce energy, occurs in the absence of oxygen
Breathing can be simply derived as the process of inhaling oxygen gas from the atmosphere and exhaling the carbon dioxide gas back into the atmosphere is termed breathing and the process is commonly known as respiration.
