Contractions of skeletal muscle around the vessels

Explanation:
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: -Accordingly, when the muscle contracts, the lymphatics collapse and propel fluid forward, with the valvular structure of the lymphatic capillaries allowing only unidirectional flow of lymph (Skalak et al. 1984). Physical exercise is brought about by muscle contractions, and the muscles can contract in several ways.
Detailed explanation-3: -How is lymph moved through lymphatic vessels? Blood cells carry lymph through the vessels.
