MICROANATOMY

Detailed explanation-1: -What Does the Lymphatic System Do? One of the lymphatic system’s major jobs is to collect extra lymph fluid from body tissues and return it to the blood. This is important because water, proteins, and other substances are always leaking out of tiny blood capillaries into the surrounding body tissues.

Detailed explanation-2: -Anatomy and physiology of the lymphatic system The primary function of the lymphatic system is to drain excess interstitial fluid leaking out from blood capillaries into the tissue spaces and transport the ultrafiltrate of extracellular fluid back to the intravascular space.

Detailed explanation-3: -These nodes filter out damaged cells, bacteria, and other foreign bodies. Once this fluid passes out of the lymph nodes, it travels to larger vessels and eventually lymph ducts, which converge in the thoracic duct at the base of the neck. The thoracic duct returns filtered lymph into the bloodstream.
