LYMPHATIC SYSTEM

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Lymph travels without a pump, instead it moves through lymph vessels with the help of valves and which type of muscle?
A
skeletal
B
smooth
C
cardiac
D
striated
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: -Fluid that is forced out of the bloodstream during normal circulation is filtered through lymph nodes to remove bacteria, abnormal cells and other matter. This fluid is then transported back into the bloodstream via the lymph vessels. Lymph only moves in one direction, toward the heart.

Detailed explanation-3: -Lymph capillaries send lymph into larger tubes called lymphatic vessels. The lymphatic vessels come together in still-larger tubes called collecting ducts. A series of valves keep the fluid moving one way. The collecting ducts empty the lymph into the right or left lymphatic duct (thoracic duct).
