What is the role of lymph in the body?

Carries oxygen
Removes waste
Delivers nutrients
Transports hormones

The correct answer is: Removes waste

The role of lymph in the body is primarily related to the removal of waste and toxins. Lymph is a clear fluid that circulates throughout the lymphatic system, which is a crucial part of the immune system. It is responsible for transporting lymphocytes, which are white blood cells that help fight infection, as well as carrying away waste products, dead cells, and other debris from tissues. As lymph is formed from interstitial fluid, it collects waste materials and other substances from the body’s tissues and eventually drains back into the bloodstream. This function is vital in maintaining fluid balance and ensuring that the body’s tissues do not become overwhelmed with waste. While other substances, such as oxygen and nutrients, are primarily transported by the blood, and hormones have their own specific transport mechanisms through the bloodstream, the lymphatic system's primary role is to assist in waste removal and immune functionality, making the indication that its role includes waste removal accurate.
