The lymphatic vessels in heart, lung, liver, kidney, and intestine. a Cardiac lymphatic vessels develop from the extracardiac region and follow the basal-to-tip manner along the developing coronary arteries to the ventricles; b Pulmonary lymphatic vessels consists of interlobular, intralobular and pleural lymphatic vessels, and develop surround airway, blood vessels and developing alveoli; c Capillary lymphatic vessels of the portal tract region mainly absorb the lymph secreted into the Disse space and eventually drain through collecting lymphatic vessels into thoracic duct; d Capsular lymphatic vessels are located near the renal surface. Cortical capillary lymphatic vessels accompany the renal tubules, glomeruli and small arteries and run along the medullary collecting lymphatic network and are finally excluded from the kidney via the hilar lymphatic vessels; e The intestinal lymphatic vessels consist of mesenteric collecting lymphatic vessels, mucosal, submucosal, muscle lymphatic vessels, and lacteals.
