Understanding the structure of these vessels can help explain their function. They are designed to efficiently transport lymph fluid and immune cells.

6. Efferent lymphatic vessels have thin walls that allow for the easy passage of lymph fluid.
7. They contain valves that prevent the backflow of lymph, ensuring it moves in one direction.
8. The walls of these vessels are lined with endothelial cells, which help regulate the passage of substances.
9. Smooth muscle cells in the vessel walls help propel lymph fluid through the vessels.
10. Efferent lymphatic vessels connect to larger lymphatic trunks, which eventually drain into the bloodstream.

Function of Efferent Lymphatic Vessels

These vessels have several important functions that contribute to the body's overall health and immune response.

11. They transport lymph fluid, which contains waste products and immune cells, away from lymph nodes.

14. These vessels help remove harmful substances, such as bacteria and viruses, from the lymph fluid.
15. Efferent lymphatic vessels also help distribute nutrients and hormones throughout the body.

Efferent Lymphatic Vessels and Disease

These vessels can be affected by various diseases and conditions, which can impact their function and the body's overall health.

16. Lymphedema is a condition where the lymphatic vessels are blocked or damaged, leading to swelling and fluid buildup.
17. Infections, such as lymphangitis, can cause inflammation of the lymphatic vessels.
18. Cancer can spread through the lymphatic system, including the efferent lymphatic vessels.
19. Autoimmune diseases, such as lupus, can affect the function of the lymphatic vessels.
20. Treatments for diseases affecting the lymphatic system may include medications, surgery, or physical therapy to improve lymphatic flow.
