👉 Bone fluid, also known as synovial fluid in joints but specifically referring to the fluid within bone cavities, is a clear, colorless liquid that plays a crucial role in maintaining bone health and function. It acts as a lubricant, reducing friction between bones during movement and facilitating smooth joint motion. Additionally, bone fluid serves as a vital transport medium for nutrients, hormones, and waste products, ensuring that bone cells receive necessary nutrients and that metabolic byproducts are efficiently removed. It also plays a role in bone remodeling, helping to regulate the balance between bone formation and resorption. Produced by osteoclasts and fibroblasts within the bone marrow, bone fluid is continuously produced and reabsorbed, maintaining its composition and volume to support the dynamic processes of bone health.
