What is the total lymph flow rate per hour?

• A. 60 cc/hr
• B. 120 cc/hr
• C. 150 cc/hr
• D. 200 cc/hr

Answer: (B)

The total lymph flow rate per hour in a healthy adult is typically estimated to be around 120 cc/hr. This value is significant as it reflects the body’s capacity to maintain fluid balance and support immune function through the lymphatic system. The lymphatic system plays a crucial role in collecting excess interstitial fluid, facilitating lipid absorption from the gastrointestinal tract, and transporting immune cells.

Understanding the lymph flow rate is essential for healthcare professionals, especially in the field of phlebology, as it helps in diagnosing and managing conditions related to lymphatic disorders, such as lymphedema or lymphatic obstruction. The range of lymph flow can vary depending on various physiological factors, but 120 cc/hr is widely accepted as a key reference point for normal lymphatic function.
