The lacrimal glands, located near the eyes, are primarily responsible for producing what substance?

Explanation

The lacrimal glands, located above and to the outer side of each eye, are primarily responsible for producing tears, which continuously help keep the surface of the eye moist, lubricated, and protected from minor debris and potential infection. Beyond this ongoing baseline tear production, these glands can also produce a noticeably larger volume of tears in response to eye irritation or strong emotional responses. Proper tear production and drainage are both important for maintaining healthy, comfortable eyes, and disruptions to either process can sometimes lead to issues like dry or excessively watery eyes.
