What is the role of the lacrimal glands?

• A. To protect the eye from infection
• B. To produce tears
• C. To control the amount of light entering the eye
• D. To change the shape of the lens

Answer: (B)

The lacrimal glands play a vital role in producing tears, which are essential for the health and functioning of the eyes. Tears serve multiple functions, including keeping the surface of the eye moist, providing necessary nutrients, and facilitating the removal of debris. When the lacrimal glands secrete tears, they help maintain the eye's lubrication, which is critical for clear vision and comfort. In addition, tears contain antibacterial agents that help protect the eyes from infections. The act of blinking spreads these tears evenly over the surface of the eye. While the other options mention functions associated with the eye, such as protecting against infection, controlling light, and changing the lens shape, these are not the primary functions of the lacrimal glands. Instead, those functions are associated with other structures in the eye, further highlighting the specific and essential role of the lacrimal glands in tear production.
