Answer 1

Answer:

part of the upper respiratory system (a) nasal chamber

Answer 2

Answer:

The answer is (d) Trachea.

Explanation:

The nasal chamber, pharynx, and larynx form the upper respiratory system and help to take in air and pass it on to the lungs. It also helps in speech as the vocal cords are contained within the larynx (also known as the voice box). The trachea connects the upper respiratory system with the lungs - bronchi, bronchioles, and the alveoli. They form the lower respiratory system which is responsible for absorbing oxygen and discharging carbon dioxide.
