Final answer:
B) transporting respiratory gases
The lymphatic system does not transport respiratory gases; its functions include draining excess interstitial fluid, carrying pathogens to lymph nodes, and transporting dietary fats.
Step-by-step explanation:
The question asks which option is NOT a function of the lymphatic system. The lymphatic system's functions include draining excess interstitial fluid, carrying pathogens to lymph nodes, and transporting dietary fats. However, it does not have a role in transporting respiratory gases, which is a function of the respiratory and circulatory systems, not the lymphatic system.
The lymphatic system is crucial in removing excess fluid from tissues, absorbing fatty acids, facilitating immune responses, and filtering out pathogens. It is closely related to the immune system and plays a significant part in maintaining homeostasis and host defense.
