What is the total lymph flow rate in the lymphatic system per hour?

• A. 60 cc/hr
• B. 90 cc/hr
• C. 120 cc/hr
• D. 150 cc/hr

Answer: (C)

The total lymph flow rate in the lymphatic system is generally accepted to be around 120 cc/hr. This figure represents the average amount of lymph fluid that is moved through the lymphatic system in a healthy adult. The lymphatic system plays a crucial role in maintaining fluid balance in the body, facilitating the return of interstitial fluid to the bloodstream, and contributing to the immune system by transporting white blood cells and filtering pathogens.

Understanding this flow rate is important for professionals in phlebology and related fields, as variations from this average may indicate underlying health issues, such as lymphedema or other lymphatic disorders. The knowledge of typical lymph flow rates helps practitioners assess and monitor patients’ vascular health effectively.
