We do, but our bodies are quite well designed in some ways ...
including having all our joints lubricated (called synovial fluid)
Friction exists in the joints between the bones. Cartilage reduces the drag.Also, blood flowing through the vessels causes friction. That is where we get the blood pressure from.
I this its the following: Bursae - located between skin and bones, tendons and bones, muscles and bones, or ligaments and bones - Main function: reduce friction between joints Joint Capsule - surrounds a synovial joint and encloses the synovial cavity - Main function: unite the articulating bones and reduce friction via production of synovial fluid
If there is no friction between the rugs and the floor, they become large skating objects that can easily dump you on your rear end, possible breaking bones.
Kinetic FrictionA more simple definition is "a force that oppsoes motion". i actually dont know the real answer so i wrote this cause it looks smart :D... sorry for wasting your time!!!!
The friction between moving particles is called friction.
Cartilage
Yes, it does, since it acts as a cushion between the bones
cartilage
Cartilage in joints REDUCE friction.
yes it reduces friction between bones, and also, synovial fluid reduces friction at the joints as well.
synovial fluid Plus the cartridge on the ends of the bones in a movable joint.
because it needs to be able to reduce friction between bones
Synovial fluid is important between the bones because it helps reduce the friction between the bones. This fluid also lets a person move his joints more freely.

A bursa acts as a cushioning and lubricating structure that reduces friction and allows for smooth movement between bones. Having a bursa between movable bones helps to prevent wear and tear on the joint surfaces, decreasing the risk of pain, inflammation, and injury.
In most cases, for adults, cartilage usually sits on ends of bones to prevent friction between other bones. -JoshuaP
