|Conjunctival mucus gland
secretion is an important part of tears.|
|Lacrimal punctum -
is an opening located at the innermost corner of both the
upper and lower lid. They collect tears from the eyes and drain it into the
|Lacrimal canaliculi - These tubes course along the inner lid margins
and join to form the lacrimal sac.|
|Lacrimal sac - Located on the inner side of the eye, between
the eye and the nose.|
|Nasolacrimal duct - It is the tube that runs from the sac into the
