Large intestine anatomy

FIGURE 6.19 The llpopiotetn map illustrates the fact that tissues can derive energy from lipoproteins formed by cells of the gut as well as by cells of the liver (hepatocytes). The chylomicrons and VLDLs are mixed together thmu out the circulatory system. Not shown is the contribution of apo C-IJ and apo E to these particles by the HDLs, The map shows that cholesterol is taken up by the peripheral tissues from the LDl, but not to a large extent from the chylomicrons or the chylomicron remnants. The map also shows that TGs are removed from lipoproteins by lipoprotein lipase, w hereas cholesterol is removed after endocytosis of the particle. Also shown is the delivery of bile, which contains bile salts, cholesterol, and phospholipids, to the small intestine, The drawmg is stylixed and does not closely represent the anatomy,...
