APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Lymph capillaries or lymphatic capillaries are tiny, thin-walled microvessels located in the spaces between cells (except in the central nervous system and non-vascular tissues) which serve to drain and process extracellular fluid.

Detailed explanation-2: -At the point where the duct empties into the subclavian vein, a small bicuspid valve prevents backflow of venous blood into the lymphatic system (Ilahi et al, 2020).

Detailed explanation-3: -Lymph vessels that carry lymph to a lymph node are called afferent lymph vessels, and those that carry it from a lymph node are called efferent lymph vessels, from where the lymph may travel to another lymph node, may be returned to a vein, or may travel to a larger lymph duct.

Detailed explanation-4: -The microvasculature consists of three types of small vessels: arterioles, capillaries, and venules. These microvessels form a network that regulates local blood perfusion and conducts blood–tissue exchange [262, 415] (Figure 1).
