IMMUNOLOGY

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 Lymph is moved through the lymphatic vessels by contractions of the lymphatic vessels and the movement of the surrounding digestive system and skeletal muscles.

Detailed explanation-3: -Contraction of skeletal muscles causes lymph to flow through the lymphatic vessels. Lymph nodes produce a type of leukocyte and antibodies to fight infection. Lymph nodes range in size from a pinhead to a golf ball. Lymphatic vessels join together to form lymphatic capillaries.

Detailed explanation-4: -The contraction of your muscles becomes the pump that helps the fluid get around your body. Exercise can help the lymphatic system flow more effectively and potentially help prevent infections and other diseases, like cancer.
