front 1 Food is contained in the gastrointestinal tract from the time of ingestion until It is completely digested and the waste prepared for elimination. | back 1 True |
front 2 The circular folds of the small intestine enhance absorption by causing the chyme to spiral, rather than move in a straight line, as it passes through the small intestine. | back 2 True |
front 3 As food passes through the digestive tract, it becomes less complex and the nutrients are more readily available to the body. | back 3 True |
front 4 Some of the microbes that often invade other organs of the body are rarely found in the stomach. The reason for this is the presence of HCI. | back 4 True |
front 5 Kupffer cells are found in the liver and are responsible for removing bacteria and worn-out cells. | back 5 True |
front 6 The pharyngeal-esophageal phase of swallowing is involuntary and is controlled by the swallowing center in the thalamus and lower pons. | back 6 False |
front 7 All the chemical ad mechanical phases of digestion from the mouth through the small intestine are directed toward changing food into forms tha can pass through the epithelial cells lining the mucosa into the underlying blood and lymphatic tissue | back 7 True |
front 8 Pepsinogen is the precursor to the gastric enzyme for protein digestion and is secreted by the parietal cells. | back 8 False |
front 9 The main chemical activity of the stomach is to begin the digestion of proteins. | back 9 True |
front 10 The major role of absorption in the ileum is to reclaim bile salts to be recycled back to the liver. | back 10 True |
front 11 The peritoneum is the most extensive serous membrane in the body. | back 11 True |
front 12 Peyers patches are found in the submucosa of the distal end of the small intestine. | back 12 True |
front 13 The myenteric nerve plexus provides the major nerve supply to the GI tract wall and controls GI motility. | back 13 Tre |
front 14 The first teeth to appear are the deciduous teeth. | back 14 True |
front 15 Dentin anchors the tooth in place. | back 15 False |
front 16 The digestive function of the liver is to produce bile. | back 16 True |
front 17 The pancreas has both an endocrine and an exocrine function | back 17 True |
front 18 Another term for swallowing is deglutition. | back 18 True |
front 19 The intrinsic ability of visceral smooth muscle to exhibit the stress-relaxation response is termed plasticity. | back 19 True |
front 20 The stomachs contractile rhythm is set by pacemaker cells found in the spinal cord. | back 20 False |
front 21 The major stimulus for production of intestinal fluid is distension or irritation of the intestinal mucosa by hypertonic or acidic chyme. | back 21 True |
front 22 Most nutrients are absorbed through the mucosa of the intestinal villi by active transport. | back 22 True |
front 23 Ionic iron is actively transported into the mucosal cells, where it binds to the protein ferritin, a phenomenon called the mucosal ion barrier. | back 23 True |
front 24 Mumps is an inflammation of the parotid glands caused by myxovirus. | back 24 True |
front 25 Fats significantly delay the emptying of the stomach | back 25 True |
front 26 The soft palate rises reflexively to open the nasopharynx when we swallow food. | back 26 False |
