Answer: C. Transporting respiratory gases
The lymphatic system is a part of the immune system, important for the cleaning within the fluids of the body. It also helps in producing an immune response to a certain disease. The lymphatic system is in no way responsible for the transport of respiratory gases. The lymphatic system has four main functions; maintaining the fluid levels of the body, cellular waste removal, protection of the body from disease-causing organisms, and ensuring a balance in body fluid levels. Although not part of the immune system, the lymphatic system is sometimes referred to as glands. This system is made up of small vesicles known as lacteals. These are used to absorb fat and fat-soluble nutrients in the gut.
