Detailed explanation-1: -The smaller lymphatic vessels, which take up the fluids, are called lymph capillaries. The larger lymphatic vessels have muscles in their walls which helps them gently and slowly pulsate. These larger lymphatic vessels also have valves that stop the lymph flowing back the wrong way.
Detailed explanation-2: -Fluid moves from the interstitial space into the lymph capillaries by means of a pressure mechanism exerted by respiration, peristalsis of the large intestine, the compression of muscles, and the pull of the skin and fascia during movement.
Detailed explanation-3: -Which of the following is not a method that maintains lymph flow? (d) Breathing. Capillaries have a thin wall of simple squamous epithelium, without a smooth muscle layer. The lymphatic trunks have smooth muscle in their wall to help move lymph back to the veins.
