Final answer:
The flow of eye irrigational fluid is directed towards the inner canthus, which helps to clear debris and maintain lubrication.
Step-by-step explanation:
The flow of eye irrigational fluid is directed towards the inner canthus.
This is because the lacrimal punctum, a small opening on the inner corner of the eye, drains the fluid into the lacrimal sac. From there, the fluid is directed towards the nasal cavity through the nasolacrimal duct, which is located towards the inner canthus. This is to ensure that any debris or hazardous material is flushed away from the lacrimal puncta, which are the small openings near the inner canthus that lead to the nasolacrimal duct. By doing so, the risk of further contamination into the tear ducts and nasolacrimal duct is minimized. This directional flow helps to clear any debris or irritants from the surface of the eye and maintain proper lubrication.
