THANK YOU

Name Digestion II: Phases of tGastric Activity Moments earlier, before your first bite, as you began to unwrap your Tastykake, its sweet aroma wafting to olfactory receptors in your nasal cavity the delicate swirl of chocolate providing a visual accent to the vanilla frosting coating the top of your crème-filled chocolate cupcake the 22 nerve, acting through the 21plexus began to increase gastric activity in what's known as the 7.phase of gastric activity. During this phase, the 36, is preparing to receive the Tastykake by increasing secretory activity. Mucous cells of the gastric 39, secrete mucous while 8 cells secrete pepsinogen (a 35 or inactive form of the 14enzyme 17.) and 25_cells secrete 2, acid (HCI). 11, cells in the 20 (a region of the stomach). also release the hormone 1..which reinforces the secretory activity of the gastric mucosa and increases gastric 28. As you begin to consume your treat, the food entering the stomach is mixed with gastric juice forming a viscous, acidic mixture known as 29.As the stomach becomes distended and pH 40,activation of both 37. receptors and chemoreceptors elicit reflexive increases in secretion and motility (as powerful 27 waves in the muscularis 13,), mediated through both the submucosal and 12,plexuses of the stomach wall. The acidic nature of gastric secretions converts 9 to pepsin allowing for the digestion of proteins while carbohydrate and lipid digestion slows under low pH conditions. After several hours, waves of smooth muscle contraction occurring throughout the pylorus, "squirt chyme past the pyloric 23, into the 6, initiating VORD the 19 phase of gastric activity. During this phase, activation of duodenal stretch and chemoreceptors in response to the arrival of chyme, 32, gastric activity and promotes 38 of the pyloric sphincter to 33 gastric emptying this is known as the 16, reflex. In addition, the presence of and decreased pH of the arriving chyme causes the release of several important hormones from 30 cells undigested carbohydrate and lipid located within the intestinal 10, of the duodenum. The release of 4.(CCK) in response to undigested carbohydrates and lipids directs the 34 release 31-rich pancreatic juice and stimulates 3 to bladder contraction; at the same time, gastric inhibitory peptide 5J. promotes 24,release from the pancreas to facilitate 26, uptake by cells, while 18 (released in response to decreased plH), promotes the release of 15-nch (HCO,) pancreatic juice to buffer the acidic chyme.
