The movement of materials into Bowman's capsule is opposed by two forces.
1) Capsule pressure (CP) produced by the walls of Bowman's capsule and fluid already
inside the capsule.
2) Colloid osmotic pressure (COP) results from the proteins in the blood. Because most proteins do not pass from the blood into the filtrate, the blood is more concentrated than the filtrate. Therefore water tends to move from the capsule back into the blood.

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.
Many structures within the kidneys rely on fluid pressure. The glomerus, Bowman's capsule, and tubules are all parts of the kidney that rely on fluid pressure to move the urine components along.

filtrate
The Tuft of capillaries, known as the glomerulus, enclosed by a fluid-filled capsule called the Bowman's capsule.
Bowman's capsule
They increase the fluid exchange inside the joint capsule, helping synovial fluid lubricate the surfaces so they have less friction.
a filtrate fluid that oozes from the glomerulus and is collected by the Bowman's capsule.

Common features:1. Articular cartilage - covers opposing bone surfaces.2. Joint cavity.3. Articular capsule - cavity enclosed by a double-layered articular capsule. Synovial membrane lines the capsule internally and covers all internal joint surfaces that are not hyaline cartilage.4. Synovial fluid: provides a slippery weight-bearing film that reduces friction. Also provides nourishment to the cartilage.5. Reinforcing ligaments: joints reinforced and strengthened by a number of ligaments.
