GENERAL HISTOLOGY

Detailed explanation-1: -Most of the lymphatic vessels have valves like those in veins to keep the lymph, which can clot, flowing in the one direction (toward the heart). Lymphatic vessels drain fluid called lymph from tissues throughout the body and return the fluid to the venous system through two collecting ducts.

Detailed explanation-2: -Answer and Explanation: The correct answer is e. Lymphatic capillaries-lymphatic vessels-lymphatic duct-subclavian vein.

Detailed explanation-3: -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.
