can the direction of flow of lymph be from extra celluar spaces to blood?
- Lymphatic capillaries form a mesh-like network of tiny tubes that are distributed throughout the tissue spaces and are located just under the skin.
- Unlike blood, which flows throughout the body in a continue loop, lymph flows in only one direction within its own lymphatic system. There are valves within the capillaries ensuring that the flow of lymph is away from the tissues.
- Lymph flow is unidirectional from the tissues through lymphatic vessels, eventually dumping lymph into the venacava.
