Probably the most famous Hooverville was the one founded on Anacostia Flats, just outside Washington, D.C., in 1932. Thousands of World War I veterans, calling themselves the Bonus Army, had arrived in the nation's capital to demand early payment of a bonus they had been promised at the end of the war.
amphipatic compounds (both hydrophilic/hydrophobic) synthesized in liver & secreted by gallbladder into intestinal lumen to emulsify fats in the intestine bile salts gut hormone secreted by intestinal cells when stomach content enters the intestine; stimulates contraction of gallbladder, release of bile acids & secretion of pancreatic enzymes
Here, bile from the gallbladder and enzymes from the pancreas and intestinal walls combine with the chyme to begin the final part of digestion. Bile liquid is created in the liver and stored in the gallbladder. Bile emulsifies (breaks into small particles) lipids (fats), which aids in the mechanical digestion of fats. The pancreas and gland cells of the small intestine secrete digestive enzymes that chemically break down complex food molecules into simpler ones.
