Capillary with intercellular cleft
WebEffect of Molecular Size on Passage Through the Pores. The width of the capillary intercellular cleft-pores, 6 to 7 nanometers, is about 20 times the diame-ter of the water molecule, which is the smallest molecule that normally passes through the capillary pores. WebMost notably, intercellular clefts are described in capillary blood vessels. The three types of capillary blood vessels are continuous, fenestrated, and discontinuous, with …

WebThis endothelial barrier forms a continuous cellular layer between the blood and brain interstitium, which is impermeable to plasmids. Capillaries with fenestrated endothelia and a continuous basement membrane are generally found in the kidney, small intestine, and salivary glands.
WebThe glomerular capillary wall or filtration barrier consists of three components: the capillary endothelium, basement membrane, and visceral epithelium (Fig. 2-2 ). The glomerulus is a unique vascular structure consisting of a capillary bed interposed between two arterioles: the afferent and efferent arterioles. WebJul 8, 2024 · During kidney development, plasma filtration does not start until capillary endothelial cells have invaded the vascular cleft of the SSB and the capillary loops have been formed (J. Zhang et al., 2024). At the same time, tubular reabsorption of the glomerular ultrafiltrate begins. ... Intercellular space is narrow and straight (double black ...
