The nose plays a role in the respiratory system as a passageway for oxygen intake.
it also plays a role in the immune system, due to the mucus, snot and boogers that accumulate, protecting the body from infection via the nasal cavity. 
it also helps with the nervous system, as it takes in smells and sends a signal to the brain telling you what that smell is.
<span>The nose also plays a role in hearing. The nasopharynx is flanked on either side by eustachian tubes. These tubes connect the nasopharynx to the middle ear. The nasopharynx fills the middle ear with air, equalizing air pressure in the ear with the atmosphere around it, which is an important part of hearing properly, though, that is robably not what you are needing to know.</span>

Triacylglycerols (tags) represent a major store of energy, allowing survival for up to several months under starvation condition
Effectus [21]

Answer: To compensate for low concentrations of carbohydrates, the body hydrolyzes TAGs to free fatty acids and glycerol, the latter of which is provided in ample supply to feed the -citric acid cycle.

<span>When the body is under starvation condition, low concentration of carbohydrates occurs, then the body hydrolyzes triacylglycerols to fatty acids and ketone bodies. Moreover, the acetyl CoA cannot be transformed into pyruvate so fatty acids cannot be converted into glucose. The other potential source of glucose is amino acids but this process is inherently inefficient and weakens the body so protein must be preserve.</span>
