Which of the following helps carry wastes and impurities away from the cells?

Circulatory system
Endocrine system
Lymphatic system
Nervous system

The correct answer is: Lymphatic system

The lymphatic system plays a crucial role in transporting excess fluids, cellular waste, and impurities away from tissues and cells, ultimately facilitating their return to the bloodstream. This system consists of a network of lymph vessels and nodes that help filter and cleanse lymph fluid, which contains waste products, bacteria, and foreign materials. By maintaining fluid balance and defending against infections, the lymphatic system significantly contributes to the body's overall health and cleanliness. In contrast, the circulatory system primarily focuses on delivering oxygen and nutrients to tissues and organs, while also removing carbon dioxide and metabolic waste products to some extent. The endocrine system is responsible for hormone secretion and regulation of bodily functions, and the nervous system primarily manages communication and responses throughout the body. Each of these systems has its distinct role, but when it comes to waste removal specifically from cellular areas, the lymphatic system is the key player.
