A schematic representation of different vascular beds. (a) Intestinal crypt. [i] A longitudinal dissection showing the anatomy of the villus and intestinal crypt. [ii] A cross-sectional view of the villus. [iii] A cross-sectional view of the intestinal crypt. [iv] An increased magnification to a portion of the villus to show the interactions between myofibroblasts and pericytes with the basement membrane and neighboring capillary network. [v] This depicts a Peyer's patch. Illustration in panel A was adapted with permission from [269]. (b) Schlemm's Canal. The Schlemm's canal is responsible for draining the aqueous humor from the trebecular meshwork to the spiscleral venous system. Although to a lesser extent, ciliary bodies are also involved in draining the aqueous humor. Illustration in panel B was adapted with permission from [100]. (c) Glymphatics. Interstitial fluid and CSF drain from the CNS and surrounding tissues through the glymphatic system. Illustration in panel C was adapted with permission from [109]
