Which of the following describes a common characteristic of serous fluid in older adults?

In older adults, a common characteristic of serous fluid is less lubrication between joints. As individuals age, changes in the composition and production of synovial fluid, which is a type of serous fluid, can occur. This often results in decreased lubrication, contributing to stiffness and discomfort in the joints.

With age, the body tends to reduce its ability to produce sufficient quantities of this fluid, which serves as a lubricant and a shock absorber for joints. Additionally, the physical properties of synovial fluid can change, including a decrease in its ability to maintain effective lubrication, leading to increased friction and wear on the joint surfaces.

This decrease in lubrication is associated with age-related changes, such as cartilage degeneration and a reduction in overall synovial fluid production, which can contribute to common conditions like osteoarthritis. Understanding these changes is essential for addressing joint health and mobility in older adults.
