Final answer:
Lymph flows toward the area of the body where it eventually drains into the bloodstream, and it passes through lymph nodes that filter out microbes and other foreign particles.
Step-by-step explanation:
The lymph flows toward the area of the body where it eventually drains into the bloodstream.
Lymphatic vessels begin as blind ending capillaries that feed into larger vessels and eventually empty into the bloodstream through ducts.
Along the way, lymph travels through lymph nodes that are found in various locations in the body.
These nodes filter out microbes and other foreign particles from lymph fluid.
