The kidney.vasa recta
An increase in blood pressure or an increase in blood volume can lead to an increase in the amount of fluid entering Bowman's capsule (glomerular filtration rate) due to increased glomerular blood flow. This can be seen in conditions such as hypertension or congestive heart failure.
They increase the fluid exchange inside the joint capsule, helping synovial fluid lubricate the surfaces so they have less friction.

It is called a Cyst
The fluid inside the cell is the cytoplasm
In our joint cavities, there is a fluid known as synovial fluid. It allows the joints to move freely and serves to reduce friction that can occur when joints move together. It is made up of hyaluronic acid.
I believe youre asking what fluid makes the joints movement fluid... the answer is synovial fluid, made of mostly water. Its held between the bones by an overall structure called the joint capsule. There are smaller, more specific parts of the joint capsule, but I wont go into detail. Synovial fluid is not secreted by the joint capsule or the surrounding cartilage, however. Since the capsule is richly vascularized but poorly innervated, it just takes in water from the bloodstream whenever necessary to keep the capsule filled. It does not create its own synovial fluid.
If you pull on the joint capsule, the walls of the capsule expand and lower the pressure on the fluid inside it. The gas then comes out of solution suddenly and forms bubbles, which then pop making a popping noise.
Because they are surrounded by a capsule which contains synovial fluid, which acts as a lubricant.
