What are vessels that carry lymph back through lymph nodes called?

Lymph vessels, also known as lymphatics, are specialized structures in the lymphatic system responsible for transporting lymph fluid from peripheral tissues back to the bloodstream. These vessels play a crucial role in the immune response by filtering lymph through lymph nodes, where immune cells can identify and respond to pathogens or foreign substances. Lymph vessels ensure that the lymph, which contains escaped fluids, proteins, and immune cells, is effectively returned to the circulatory system. This process is vital for maintaining fluid balance in the body and supporting overall immune function.

The distinction between lymph vessels and other types, such as pulmonary, renal, and systemic vessels, lies in their specific functions and the types of fluids they carry. Pulmonary vessels are involved in the transport of blood to and from the lungs, renal vessels supply the kidneys, and systemic vessels are part of the broader circulatory network that carries oxygenated blood throughout the body. Thus, lymph vessels specifically refer to those that deal with lymph fluid, making them the correct choice in this context.
