The lymphatic system is a one way system that begins in the tissues and ends when it reaches the blood vessels. the system helps the body maintain homeostasis by collecting accumulated tissue fluid around cells and returning it to blood circulation. the lymphatics play an active part in the immune defenses by filtering out and destroying foreign substances and microorganisms; and also help in digestion by absorbing fats from the small intestine.

lymphatic capillaries
Lymph returns to the circulatory system by entering large veins near the heart.

subclavian vein
The carotid artery supplies the head with blood and the jugular vein returns it to the heart.
Chronic Venous Insufficiency
The venous circulation of the legs requires muscle contractions to assist with blood return. Walking helps provide this muscle contraction.
venous circulation
Lymph Vessels return intercellular fluid to the veins.
Lymphocytes leave and enter lymph node via high endothelial venules. Lymph flow is slow so you have the muscular pump from skeletal muscles and the respiratory pump... similar to venous blood flow.
