what is thin walled tubes that carry lymph fluid to the larger lymphatic vessels?
Lymph is a fluid which bathes all the cells of the body. It is also called ICF (Intercellular fluid). This is made up of mostly fluid that escapes from the blood through the walls of the capillaries. Tiny, lymphatic capillaries are found in all tissues of the body. These join to form lymph vessels which are thin walled vessels that also contain valves to prevent backflow. Eventually, all lymph returns to the circulatory system through various ducts that empty into large veins below the neck. In this way, fluid that is lost through the capillary is returned to the blood. At intervals along the lymph vessels, there are bead-like enlargements called lymph nodes.
