Which of the following is NOT a function of the lymphatic system?

The lymphatic system plays several vital roles in maintaining the body’s health, but producing hormones is not one of its primary functions. The functions of the lymphatic system include transporting lymph—a fluid containing infection-fighting white blood cells—throughout the body, and thus it is integral to the immune system, helping to defend against infections. Additionally, it plays a crucial role in maintaining fluid balance by collecting excess interstitial fluid and returning it to the bloodstream, preventing edema.

While other systems, such as the endocrine system, are responsible for hormone production, the lymphatic system does not produce hormones itself. Therefore, identifying this function as not belonging to the lymphatic system is accurate and highlights the distinct roles different systems play in the body.
