Into what system does the lymphatic system empty?

The lymphatic system primarily empties into the circulatory system, specifically at the subclavian veins located near the neck. The lymphatic system is responsible for collecting excess interstitial fluid, filtering it through lymph nodes, and transporting it back to the bloodstream. This process is crucial for maintaining fluid balance in the body, facilitating immune responses, and absorbing dietary fats.

Within the circulatory system, the lymph, which is a clear fluid containing white blood cells and other substances, becomes part of the blood plasma. Once absorbed into the circulatory system, the lymph mixes with blood, allowing immune cells to circulate throughout the body and helping to distribute hormones, nutrients, and other essential substances. This integration underscores the vital role of the lymphatic system in supporting overall bodily functions and homeostasis.
