Question

1. How does fluid move from blood to lymphatic vessels?

2. How does lymph move through the body?

3. Where does lymph drain into from the left and right sides of the body? Where does lymph ultimately drain into?

Answer 1

1. At capillary level, at arterial side of the capillaries, fluid is filtered into the interstitial soace while at the venous end of the cpaillaries, fluid moves back into the capillaries. Any fluid remain in the interstitium returs back to the circulation via lymphatic channels that reabsorb the fluid through their porous lymphatic channels.

2. lymph moves through the body via lymphatic vessels and ducts.

3. Left side of body and right lower half of the body is drained by the thoracic duct while right upper half of the body is drained by the right lymphatic duct. All these lymphs ultimately drain into the subclavian vein.
