What Part of the Human Body Is the Cleanest?

Because of its ability to clean itself, the eye is frequently regarded the cleanest feature of the human body. To keep the eye clean and moist, the eyelid opens and closes numerous times every minute.

Tears are another way for the eye to defend itself. Tears are produced by the lacrimal gland in each eye and assist in the removal of debris, pathogens, and other foreign particles such as dust. The lacrimal gland is located above each eye’s outer corner.

The eyelids also have good reflex control, which allows them to assist avoid eye injuries. When the eyelids close reflexively when exposed to bright light from dim light or when an object approaches too close to the eye, this is an example of the eye’s reflex control. Eyelashes also keep dirt out of the eyes, which helps to keep them clean.

The eye is made up of various elements that allow humans to perceive light and see. The retina is the sensitive tissue lining that surrounds the inner surface of the eye. In the retina, there are cone cells that perceive colour and rod cells that detect low light contrasts. The iris is the primary opening of the eye that surrounds the pupil and controls the size of the pupil. The iris is the pigmented component of the eye that determines whether a person’s eyes are brown, blue, green, or hazel.
