How does sand get in your eye when you sleep?
The plica (PLY-ka) semilunaris (sem-ee-LOO-ner-is), which is located around the eye was thought to have no function. But eventually it was discovered that this "useless" organ has an important function after all. In fact, it is the "crusty" factory. It secretes a sticky mass that collects any foreign materials such as dust or pollen. All this trash is surrounded by the sticky gook so that it does not scratch the sensitive cornea in your eye. Once the garbage is collected, the plica semilunaris "escorts" it out of the eye just like a security guard would escort noisy troublemakers out of a theater.

I'm not a doctor, but both my knees crack constantly as long as I can remember. I was told many years ago that I had bilateral plica syndrome. If you look that up, it does mention clicking of the knee as a symptom.
What is purpose of the plica circularis and intestinal villi?
Depending on where the villi are located, they generally increase absorption surface area. (Such as the villi in the small intestine.)The villi is a kind of protection around the small intestine that makes the space bigger for more molecules to enter. You can not see the villi with a naked eye.It is shaped like little fingers pointing out from the intestine, if you have coeliac disease then they may become damaged and swollen.
What is the function of plica semilunaris in the eye?
The plica semilunaris is the vestigial remains of the nictitating membrane (or 'third eyelid') found in many fish, birds, and a few mammals. The plica semilunaris and its connected muscles serve no current function, but certainly did in human ancestral species, protecting the eye from foreign contaminants.
What is the common name for the nictitiating membrane?
It is often called a third eyelid or haw (and may be referred to as the plica semilunaris or palpebra tertiain scientific terminology).

What is a nictating membrane?
The nictitating membrane (from Latin nictare, to blink) is a transparent or Translucentthird Eyelidpresent in some animals that can be drawn across the Eyefor protection and to moisten the eye while also keeping visibility. Various reptiles, birds, and Sharkhave a full nictitating membrane, whereas, in many Mammals, there is a small Vestigialremnant of the membrane present in the corner of the eye. Some mammals, such as Camel, Polar_bear, Pinniped, and Aardvark, also have a full nictitating membrane. It is often called a third eyelid or haw and may be referred to as the Plica_semilunaris_of_the_conjunctivaor palpebra tertia in scientific terminology.Nictitating membranes are found in Bird, Reptile, Amphibian, Fish, but are less common in Mammal, mainly being present in Monotremeand Marsupial.Answers.comIn humans, the plica semilunaris and its associated muscles are thought to be the vestigial remnants of the nictitating membrane and its muscles.Answers.comCharles Darwin reported that the plica semilunaris is slightly larger in Africans and Australian Aborigines than in other peoples.Answers.comOnly one species of Primate---theCalabar_angwantibo---isknown to have a functioning nictitating membrane.Answers.comFile:Haliaeetus_leucocephalus_LC0198.jpgFile:Haliaeetus_leucocephalus_LC0198.jpgThe nictitating membrane (mid-blink) of a Bald_EagleFile:Gray892.pngFile:Gray892.pngThe plica semilunaris is thought to be the vestigial remnant of a nictitating membrane in humans.Unlike the upper and lower eyelids, the nictitating membrane moves horizontally across the eyeball. It is normally translucent. In some diving animals, for example Beaverand Manatee, it moves across the eye to protect it while under water, and in these species it is transparent; in other diving animals including Sea_lion, it is activated on land, to remove sand and other debris. This is its function in most animals. In birds of prey, it also serves to protect the parents' eyes from their chicks while they are feeding them, and when Peregrine_falconsgo into their 200 mph dives, they will blink repeatedly with the nictitating membrane to clear debris and spread moisture across the eye. In polar bears it protects the eyes from Snow_blindness. In sharks it protects the eye while the shark strikes at its prey. Woodpeckerstighten their nictitating membrane a millisecond prior to their beak impacting the trunk of a tree in order to prevent their eyes from leaving their sockets.Answers.comThe nictitating membrane in Catand Dogdoes not have many muscle fibers and consequently is not usually visible, and its being chronically visible should be taken as a sign of poor condition or ill health. It can, however, be seen clearly when gently opening the eye of the healthy animal when it is asleep, or pushing down/applying pressure on the eyeball will cause it to appear. In some breeds of dogs, the nictitating membrane can be prone to Prolapse, resulting in a condition called Cherry_eye. Birds can actively control their nictitating membraneAnswers.comIn many species, any stimulus to the eyeball (such as a puff of air) will result in reflex nictitating membrane response. This reflex is widely used as the basis for experiments on Classical_conditioningin Rabbit.Answers.comi hope that answers your question =D
