7. A major distinction between the lymphatic and cardiovascular systems in humans is that lymph is not actively pumped by the heart, but is forced through the vessels by the movements of the body, the contraction of skeletal muscles during body movements, and breathing. Lymph flows from the lymphatic capillaries, through lymphatic vessels, and then is dumped into the circulatory system via the lymphatic ducts located at the junction of the jugular and subclavian veins in the neck. tonsils.

The larger vessels contain valves to prevent backflow and pump towards the heart to return lymph fluid to the bloodstream by the subclavian veins. The swelling of lymph nodes during an infection and the transport of lymphocytes via the lymphatic vessels are but two examples of the many connections between these critical organ systems. Lymph reenters the cardiovascular system at subclavian veins situated near the neck. They . 8. 5. Match the fractions, percentage and decimals 8p Matching Game. Complement proteins are found in blood plasma. A naïve lymphocyte is one that has left the primary organ and entered a secondary lymphoid organ.
