Lacrimal duct
Lacrimal Duct
The Lacrimal Duct (pronounced: /ˈlækrɪməl dʌkt/), also known as the tear duct, is a part of the lacrimal apparatus in the human body. The term "lacrimal" is derived from the Latin word "lacrima," which means "tear."
Anatomy
The lacrimal duct is a small tube that extends from the lacrimal sac to the nasolacrimal duct. It is responsible for the drainage of tears from the eye to the nose. This duct is located in the medial part of the eye socket and is approximately 2 cm long.
Function
The primary function of the lacrimal duct is to transport tears from the lacrimal gland, which produces tears, to the surface of the eye. From there, the tears drain into the lacrimal sac and then through the lacrimal duct into the nose. This process helps to keep the eye moist and remove any debris that may have entered the eye.
