Clinical Consideration
Nerves, blood vascular and lymphatic vessels are wrapped in layers of
connective tissue (CT) or fascia – considered to be a form of CT. Recent
studies indicate that CT can dynamically regulate its tension (Langevin et
al. 2013) suggesting that changes in tissue tension could affect the
functioning of the surrounding enveloped structures. Releasing undue
tension may improve neural function and fluid flow.
Lymphatic vessels contain more valves and more frequent anastomoses than
blood circulatory vessels, thereby reducing back flow and creating an extensive,
connected network of tubes (Marieb 2003, Macdonald et al. 2008). The smaller,
thin-walled lymph capillaries are slightly larger than those seen in the blood
vascular system. Unlike the tightly joined endothelial cells lining blood vascular
capillaries, lymph capillary endothelial cells loosely overlap, augmenting
porosity thereby facilitating the collection of larger molecules.
Afferent lymphatic vessels: carry unfiltered lymph into the nodes, where waste
products and some of the fluid is filtered out.
Efferent lymphatic vessels: carry the filtered lymph out of the node to continue
its return to the circulatory system.
