Lymph and Its Circulation
Captions available
The idea
Lymph is fluid that leaves the bloodstream into tissues, is collected by lymphatic vessels, and is returned to the bloodstream.
In practice
Lymph travels in one direction only, toward the heart.
Where people slip
The lymphatic system has no pump. Movement depends on muscle activity and vessel valves.
