Lymphatic vessels
Small lymphatic capillaries anastomose to form larger lymphatic vessels that possess smooth muscle in their wall. Oriented circularly around the lumen, the smooth muscle aids in propelling lymph through the system. The outer layer of the vessel consists of an adventitia composed of connective tissue. 200x (l); 600x (r).

Valve leaflets >
In larger vessels, valve leaflets are supported by a core of connective tissue.
- Endothelial cells
In larger vessels, valve leaflets are supported by a core of connective tissue.
- Connective tissue
In larger vessels, valve leaflets are supported by a core of connective tissue.
Blood cells >
Lymph vessels play an important role in transporting white blood cells, mostly lymphocytes, from diffuse and nodular connective to lymph nodes. Red blood cells are not normally present in lymph.
