Question

Medicines dropped in the eye flow down into the nose.

Give reason:

Sometimes medicines dropped into the eyes come into the nose and even throat.

Medicines dropped in the eye flow down into the nose because of the existence of the nasolacrimal duct, which connects the eyes with the nasal cavity. This duct allows things, including medicines, to travel from the eyes to the nose.
