Study Notes
- The lymph vascular system circulates lymph throughout the body and returns extracellular fluid to the blood.
- It plays a role in maintaining the volume of extracellular fluid and transports lymphocytes and antibodies.
- The system consists of lymphatic vessels and lymphoid organs.
- Lymphatic vessels convey fluids from tissues to the bloodstream and have lymph capillaries and collecting vessels.
- Lymph nodes are small bodies that filter bacteria and foreign particles from lymph fluid.
- Lymph nodes have a cortex and medulla, surrounded by a thick capsule.
- The nodes produce lymphocytes and plasma cells and have immunological functions.
- There are two lymph ducts: the thoracic and right lymphatic ducts.
- Lymph flows away from tissues to lymph nodes and eventually to subclavian veins.
- The lymphatic system does not have vessels in the central nervous system, cartilage, bone, or epidermis.
