the walls of lymphatic vessels are similar to those of veins
Afferent lymphatic vessels
The right lymphatic duct.
Afferent lymphaticvesselthe only one that drain the excess fluid from the body to the lymph node. So, it's the smallest lymphatic structure.
Collect the fluid that leaks from blood and return it to the blood.
The lymphatic structure that absorbs lipids in the intestine is called the lacteal. Lacteals are specialized lymphatic capillaries located in the villi of the small intestine, where they capture fatty acids and glycerol from digested lipids. Once absorbed, these lipids are transported in the lymphatic system before entering the bloodstream. This process is crucial for the efficient absorption of dietary fats.
Lymphatics resemble veins in structure but have thinner walls and more valves.
Thymus
The larger lymphatic vessels are most similar in structure to veins, as they both have valves to prevent backflow and are composed of three layers: tunica intima, tunica media, and tunica adventitia. However, lymphatic vessels have thinner walls and lack a continuous layer of smooth muscle like veins do.
Tonsils
An efferent vessel typically empties into a larger blood vessel or structure, such as a vein or lymphatic duct, depending on its function. In the context of the circulatory system, efferent vessels carry blood away from an organ or tissue, such as the efferent arterioles that transport blood away from the kidneys. In the lymphatic system, efferent lymphatic vessels drain lymph from lymph nodes into larger lymphatic trunks.
