Lymphatic capillaries
Lymphatic capillaries are tiny, thin-walled vessels that are part of the lymphatic system, which helps maintain fluid balance and supports immune function. They are located throughout the body, closely following blood vessels, and are specialized to absorb excess tissue fluid, called lymph, along with waste products, bacteria, and other particles. The walls of these capillaries are loosely structured, allowing them to easily take in fluid and substances. Once the lymph is collected, it flows through larger lymphatic vessels to lymph nodes and eventually back into the bloodstream, playing a key role in immune defense and fluid regulation.
