Answer 1

Answer:

Nostrils: A nostril is one of the two holes in your nose through which you breathe, smell and sneeze.

Pharynx: The muscular tubular passage of the vertebrate digestive and respiratory tracts extending from the back of the nasal cavity and mouth to the oesophagus.

Trachea: The trachea serves as the main passage way through which air passes from the upper respiratory tracts to the lungs.

Bronchi: The bronchi singularly known as bronchus are extensions of the windpipe that shuttle air to and from the lungs.

Lungs: Lungs are sacks of tissue located just below the rib cage and above the diaphragm.

Alveoli: Alveoli are tiny sacks within our lungs that allow oxygen and carbon dioxide to move between the lungs and bloodstreams.

Diaphragm: Diaphragm, dome-shaped, muscular and membranous structure that separates the thoracic (chest) and abdominal cavities in mammals; it is the principal muscle of respiration.
