Detailed explanation-1: -There is no pump in the lymphatic system like the heart in the cardiovascular system. The pressure gradients to move lymph through the vessels come from the skeletal muscle action, respiratory movement, and contraction of smooth muscle in vessel walls.

Detailed explanation-2: -The lymphatic system uses pressure, muscle contractions, and one-way valves to squeeze fluid through a network of vessels without the need for a pump.

Detailed explanation-3: -At rest, approximately 1/3 of lymph transport in the human lower extremities results from compression by skeletal muscle contractions (extrinsic pump) and 2/3 to active pumping (intrinsic pump) of the collecting vessel network (Engeset et al. 1977).

Detailed explanation-4: -You have nodes throughout your body. The lymphatic system does different things: it acts as a one-way drainage system – this means it moves fluid from body tissues into the blood circulation. it contains white blood cells called lymphocytes, which fight infection.
