where does lymph fluid drain in order to go back into the cardiovascular system?
the subclavian veins
the lymphatic vessels (or lymph vessels or lymphatics) are thin-walled vessels (tubes) structured like blood vessels, that carry lymph. as part of the lymphatic system, lymph vessels are complementary to the cardiovascular system. lymph vessels are lined by endothelial cells, and have a thin layer of smooth muscle, and adventitia that binds the lymph vessels to the surrounding tissue. lymph vessels are devoted to the propulsion of the lymph from the lymph capillaries, which are mainly concerned with absorption of interstitial fluid from the tissues. lymph capillaries are slightly larger than their counterpart capillaries of the vascular system. 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. lymph ducts drain the lymph into one of the subclavian veins and thus return it to general circulation.
lymphatic vessel
lymph is present throughout the body, and circulates through lymphatic vessels. these drain into and from lymph nodesafferent vessels drain into nodes, and efferent vessels from nodes. when lymph fluid enters a node, it drains into the node just beneath the capsule in a space called the subcapsular sinus. the subcapsular sinus drains into trabecular sinuses and finally into medullary sinuses. the sinus space is criss-crossed by the pseudopods of macrophages, which act to trap foreign particles and filter the lymph. the medullary sinuses converge at the hilum and lymph then leaves the lymph node via the "efferent lymphatic vessel" towards either a more central lymph node or ultimately for drainage into a central venous subclavian blood vessel.
