Final answer:
Children's susceptibility to otitis media is influenced by their shorter eustachian tubes, higher frequency of respiratory infections, and bottle feeding while lying down.
Step-by-step explanation:
Children's susceptibility to otitis media
Children are more susceptible to otitis media (ear infections) compared to adults due to several factors.
Firstly, children have shorter and more horizontal eustachian tubes, which makes it easier for bacteria and fluid to travel from the nasopharynx to the middle ear. Additionally, children tend to have more upper respiratory infections, which can lead to blockage and fluid accumulation in the middle ear.
Furthermore, bottle feeding while lying down can increase the risk of otitis media. The sucking action on the bottle creates negative pressure in the eustachian tube, promoting the movement of fluid and bacteria from the nasopharynx to the middle ear.
