👉 Bears' fluid, also known as synovial fluid, is a vital component of their joints and other connective tissues. It acts as a lubricant, reducing friction between bones during movement, which allows for smooth and pain-free motion. This fluid also provides nutrients to cartilage and helps remove waste products, contributing to the overall health and functionality of joints. In bears, this fluid is particularly important due to their large size and the physical demands of their lifestyle, including swimming and climbing. Additionally, synovial fluid in bears plays a role in shock absorption, protecting joints from damage during high-impact activities.
