Lymphatic drainage of the ileum associated with Peyer's patches begins with lymph entering a single lacteal of the villus, probably through intercellular flaps, which prevent retrograde flow to the interstitium. These lacteals are continuous with an interconnecting plexus of branching sinuses which surrounds the crypts and follicle domes in the lamina propria. Small vessels emanating from this plexus penetrate the muscularis mucosa, where lymph can either flow within septal vessels to the deep submucosa, or enter the follicular sinuses to move freely around follicles, and through gaps in septal walls. All lymph enters a deep submucosal network where retrograde flow is prevented by valves. Lymph is then conveyed through vessels passing between the fibres of the muscularis externa to other lymphatics, which transport lymph from the ileal surface to the mesenteric nodes.
与派尔集合淋巴结相关的回肠淋巴引流始于淋巴进入绒毛的单个乳糜管,可能是通过防止淋巴逆流至间质的细胞间皮瓣。这些乳糜管与一个相互连接的分支窦丛相连,该窦丛围绕固有层中的隐窝和滤泡圆顶。从这个窦丛发出的小血管穿透黏膜肌层,在黏膜肌层中,淋巴要么在间隔血管内流向深层黏膜下层,要么进入滤泡窦在滤泡周围自由流动,并通过间隔壁上的间隙。所有淋巴进入深层黏膜下网络,此处的瓣膜可防止淋巴逆流。然后,淋巴通过在肌层外纤维之间穿行的血管输送到其他淋巴管,这些淋巴管将淋巴从回肠表面输送至肠系膜淋巴结。
