GENERAL HISTOLOGY

Detailed explanation-1: -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: -The lymphatic system begins with initial finger-shaped lymphatic vessels consisting of valveless lymphatic capillaries and precollectors with valves. The precollectors become collectors and transport the lymph to the so-called lymph stems.

Detailed explanation-3: -Answer and Explanation: The statement that is incorrect about lymph vessels is a) the right lymphatic duct returns lymph to the inferior vena cava. The right lymphatic duct drains into the right subclavian vein.

Detailed explanation-4: -To ensure that fluid does not flow backward, all lymphatic have one-way valves. The forward flow of lymph is due to the pressure gradient created by the muscle contractions and respiratory movements. The key feature of lymphatic vessels is that they have thin endothelial walls and have an overlapping arrangement.
