We do, but our bodies are quite well designed in some ways ...
including having all our joints lubricated (called synovial fluid)
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
Lubricating fluids like synovial fluid in the joint help reduce friction by providing a smooth surface for bones to glide against each other. Additionally, the cartilage covering the ends of bones acts as a cushion, reducing friction during movement. Strengthening the muscles around the joint can also help stabilize and support it, reducing friction.
A example of friction is rubbing your hands together the heat you feel is friction. Oh dont be a shat head.
Friction can occur between body tissues or organs, particularly in joints. This can lead to conditions like arthritis or stiffness. However, the human body is also equipped with lubricating substances like synovial fluid to reduce friction and promote smooth movement.
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!!!!
Cartilage
Yes, it does, since it acts as a cushion between the bones
cartilage
Cartilage in joints REDUCE friction.
Synovial fluid reduces friction between bones at joints. It is a lubricating fluid secreted by the synovial membrane and contains hyaluronic acid and lubricin to facilitate smooth movement between bones.
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.
In most cases, for adults, cartilage usually sits on ends of bones to prevent friction between other bones. -JoshuaP
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.
Cartilage keeps bones from rubbing together and provides a smooth surface for movement at the joints
The cavity between bones at the joint is known as the synovial cavity. This space is filled with synovial fluid, which helps to reduce friction and facilitate smooth movement of the bones at the joint.
