Saliva is the watery liquid that keeps your mouth moist. It is produced by the salivary glands and helps with digestion by breaking down food and keeping the mouth clean.
The salivary glands secrete saliva into the mouth. Saliva has much importance to survival, because it begins to break down food, as part of the digestive system, and it keeps the esophagus lubricated when food goes down. Saliva also keeps the mouth clean, because it flushes out bacteria.
An emulsifier is the substance that keeps the liquid components in an emulsion from separating. Emulsifiers work by lowering the surface tension between the two liquids, allowing them to mix and remain stable. Common emulsifiers include lecithin, egg yolks, and certain proteins.
A barometer is an instrument that keeps a continuous record of air pressure. It consists of a glass tube filled with mercury or other liquid that rises and falls based on changes in atmospheric pressure. The fluctuations in the liquid's height are used to determine changes in air pressure over time.
The forces of attraction between liquid atoms and liquid are more therefore they are close to another. This is what that keeps them close to each other.

It keeps the internal parts lubricated
The cartilage, that is the tissue that lays between the joints of the bone. cartilage provides a tough surface which when lubricated with sinovial fluid keeps joints moving freely and painlessly. when this material starts to break down as a result of trauma or just wear and tear you end up with what is known as OA.
it keeps the throat lubricated to allow oxygen to enter the lungs easily
If you mean what keeps joints firm with bones and muscles....then it makes sense, there are no joints that help joints...Tissue connects bones to the joints which connects bones. almost as if you were to connect bricks by using cement. In this case, the tissue would be the cement...i hope this sorta hdelped ish
Cartilage. Also, tendons and muscle.
This residue that you are speaking of is most likely the mucus that keeps your rectum lubricated when you have a bowel movement. Having a little mucus drip onto your underwear is normal, but contact your doctor if the mucus turns bloody.

Oil is not a coolant, it is a lubricant, but it keeps the engine lubricated to prevent friction, which reduces heat and makes is run cooler. Water in the radiator, and the radiator fan, is what keeps the engine cool.
ligaments
because it keeps the parts lubricated, which in turn allows them to do more, and last logner. It reduces friction.
