Solution
-
The primary function of the fine hairs lining the nasal passages is the filtration of air.
-
Alveoli are described as balloon-like structures.
-
The pigment present in red blood cells and is responsible for oxygen transport is Haemoglobin.
-
In the respiratory system diagram, A) is the Nasal passage, B) is the lungs, and C) is the Diaphragm.
-
The organ that acts as the pumping organ to push blood around the body is the Heart.
-
The true statement about the relationship between autotrophs and heterotrophs is that heterotrophs depend directly or indirectly on autotrophs for their survival.
-
The term used to describe the volume of air remaining in the lungs after a forceful exhalation is Residual volume.

Air is breathed in through the nose to the nasal cavity, where a layer of nasal mucosa acts as a filter and traps pollutants and other harmful substances found in the air. Next, air moves into the pharynx, a passage that contains the intersection between the oesophagus and the larynx. The opening of the larynx has a special flap of cartilage, the epiglottis, that opens to allow air to pass through but closes to prevent food from moving into the airway.
