Can you explain this answer?

Answer

Air passes in our body by the respiration process as follows:-
Air enters our body through the nasal cavity . When it passes through the nose , the extra particles present in the air are trapped by the mucus and hair present in the inner lining of nose. From the nasal cavity air passes to the pharynx . Pharynx is it tube which is connected with the digestive system. From this tube pharynx , the air reaches larynx . Larynx is also known as the voice box . The vocal cords present in larynx help us to produce vocal sounds . From larynx , the air moves to trachea . Trachea is also known as windpipe which is connected to the chest. In the lungs pressure device to form right and left bronchi. Mucus in the bronchi traps the extra particles present in the air. Finally the air travels from the bronchi to the small passages called bronchioles.

Answer

In respiration air passes first through the nose or nasal cavity where it contain so many hair and mucous which filters the dust particles which come along with the air .Then this air goes to the pharynx which is the common passageway for food and water and this air goes to the larynx or voice box which when vibrated when air pass through it which helps us to talk. Then air goes to the windpipe or tranchea. Tranchea is a long tube which contain mucous which filters the dust particles that enter with the air.Then this air goes to the bronchi present in the lungs and this bronchi get subdivided into bronchioles and air goes to the bronchioles. In the end of every bronchioles there is an round ball like structure called as alveoli and the air enters it.

Answer

Respiration Process:
In the process of respiration, air passes through different organs in a specific order to reach the lungs for the exchange of gases.

Sequence of Respiratory Organs:
- Nasal Cavity: Air enters the body through the nasal cavity where it gets filtered, warmed, and moistened.
- Pharynx: From the nasal cavity, air moves to the pharynx, which is a passage for both air and food.
- Larynx: The air then travels to the larynx, commonly known as the voice box, which helps in producing sound.
- Trachea: Next, the air passes through the trachea, a tube that connects the larynx to the bronchi.
- Bronchi: The trachea branches into two bronchi, one entering each lung, to further distribute air.
- Bronchioles: Finally, the bronchi divide into smaller tubes called bronchioles, which lead air to the alveoli in the lungs for gas exchange.

Correct Sequence:
The correct sequence of organs through which air passes during respiration is from the nasal cavity, pharynx, larynx, trachea, bronchi, and bronchioles (Option B). This specific pathway ensures that air is properly filtered, warmed, and reaches the lungs for the exchange of gases efficiently.
By following this sequence, the respiratory system can perform its vital function of supplying oxygen to the body and removing carbon dioxide effectively.
