Efferent neurons are the motor neurons which communicate information in the opposite direction as compared to the afferent neurons, that is, they communicate information or response impulses from the brain or central nervous system to the muscles or glands.
The response impulses results in the movement of the muscles or activation/deactivation of certain gland
In contrast, afferent neurons are the sensory neurons which carry impulses from the receptors to the central nervous system.
The lymphatic system is to carry lymph nodes, lymph, and lymphatic vessels. However, it is not structured to carry blood along its way. The human's lymphatic system's function is to move the lymph from tissues to the bloodstream.
