Why do elephants cry?
With nowhere to go, the tear fluid accumulates at the medial canthus (the inner corner of the eye) and then spills out from there down the face. There is actually a diagonal groove in the skin next to the inner corner of the eye in both species of elephants that serves to draw the liquid down and away from the eye where it can evaporate. In all living elephants, this groove and the skin below the end of it are constantly moist with shed tear film. Sometimes a "white goop" or "foam" is visible at the medial canthus of an elephant's eyes; while there does not appear to be scientific literature directly address the cause of it, it is presumed to be an accumulation of sebum and mucous from the tear film, as well as potentially a deposit for bacteria and physical irritants that have been cleared out of the eye. When it is windy or there is particulate matter in the air (such as smoke) it is presumed that the nictitating membrane works overtime, both in producing more tear film and in sweeping debris away; as a result, elephants are often seen with more fluid below their eyes and more foam in the medial canthus during adverse weather conditions.
What is the set of glands and ducts around the eyes involved in this process called?
The set of glands and ducts around the eyes involved in this process is called the “lacrimal apparatus.”.

Why don't elephants have tear ducts?
The reason all of the above matters with regards to elephants is because their evolutionary ancestors threw out that entire system and developed something else instead. Not only do elephants not have tear ducts, they actually don't have any piece of the normal mammalian lacrimal apparatus: that means no lacrimal gland, no tear ducts, no canaliculi at the corners of their eyes, and no canals for drainage of tear fluid into their nasal cavities. This is currently thought to be an adaptation that developed during a period where the ancestors of modern-day elephants were semi-aquatic; this seems credible, since modern-day pinnipeds also lack a lacrimal apparatus. (The same physiological changes discussed in this section are also found in elephants' closest living relatives, hyrax and manatees.)
