Question

What is lymph? How its composition differ from blood plasma? What is the direction of its flow?

Answer 1

Lymph :- Lymph is the fluid that circulates throughout the lymphatic system. The lymph is formed when the interstitial fluid is collected through lymph capillaries.
Unlike blood, which flows throughout the body in a continue loop, lymph flows in only one direction within its own system. This flow is only upward toward the neck. Here, it flows into the venous blood stream through the subclavien veins which are located on either sides of the neck near the collarbones.
