What do body fluids include in a healthcare context?

In a healthcare context, body fluids encompass a wide array of substances, including but not limited to blood, urine, saliva, mucus, tears, synovial fluid, and cerebrospinal fluid. These fluids play crucial roles in various physiological functions, such as circulation, digestion, and lubrication of joints.

The correct answer reflects this broader definition, acknowledging that body fluids also include substances produced by glands, secretions that assist in digestion, and fluids that help protect and nourish tissues and organs. Recognizing this comprehensive range of body fluids is essential for understanding their significance in medical assessments, diagnostic procedures, and patient care.

The other options fail to capture the full spectrum of what is considered body fluids, limiting their definitions and overlooking important components that are vital in healthcare settings.
