Capillary type, illustration 插畫檔

Illustration of a comparative microscopic analysis of three primary capillary types. The left panel illustrates continuous capillaries characterised by tightly joined endothelial cells and an intact basement membrane, typically observed in muscle tissue. The middle panel depicts fenestrated capillaries containing endothelial pores that facilitate substance exchange, predominantly located in the kidneys. The right panel displays sinusoidal capillaries featuring large lumens and discontinuous basement membranes with extremely high permeability, commonly found in the liver. Red blood cells and pericytes are also labelled within the micrographs
