At what rate does lymph re-enter the general circulation per hour?

The lymphatic system plays a critical role in maintaining fluid balance within the body by collecting excess interstitial fluid and returning it to the bloodstream. Generally, the rate at which lymph re-enters the general circulation is approximately 125 mL per hour in a healthy adult. This figure indicates the efficiency of the lymphatic system in balancing fluid and helping in the transport of immune cells and waste products.

This rate can vary based on factors such as hydration level, physical activity, and overall health, but the 125 mL per hour is a well-regarded estimate used in clinical discussions. Understanding this metric is crucial in the field of cardiovascular perfusion as it ties into the fluid dynamics and the body’s homeostasis during various medical procedures and treatments.
