Lymphatic System: How Lymph Flows and What It Does

Lymphatic System Overview

Lymph forms in tissues and is collected by lymphatic capillaries (tiny vessels between cells). These merge into larger lymphatic vessels that transport lymph to lymph nodes.

Lymph nodes are small, bean-shaped organs that filter bacteria, viruses, and foreign particles from lymph. Filtered lymph then empties into the bloodstream.

The lymphatic system is a vital part of the immune system, protecting the body from infection.
