Lymphatic Vessels

The lymphatic structure is based on that of blood vessels.

The lymphatic system comprises a network of conduits called lymphatic vessels that carry lymph unidirectionally towards the heart.

Lymph circulates to the lymph node via afferent lymphatic vessels and drains into the lymph node in the subcapsular sinus.

Lymph capillaries are tiny, thin-walled vessels, closed at one end and located in the spaces between cells throughout the body.

The lymph trunks drain into the lymph ducts, which in turn return lymph to the blood by emptying into the respective subclavian veins.
