medical management, oral characteristics observed and finally dental management and oral hygiene care. First one must understand what exactly a peptic ulcer is. Peptic meaning, “a description relating to digestion in the upper digestive system (the stomach and small intestine)”…

view for such observation. The material found in the stomach is most likely the gastric juice (hydrochloric acid). The main explanation as to why the fetal pig has no food in the stomach is because it is fetal. It can be concluded that it did not have access to the outside environment thus gaining no access to food. Furthermore, if the fetal pig did indeed gain access to food, the remainders of the nourishment would not be present in the stomach due to the hydrochloric acid dissolving the…

water to cover the gills without getting inside the body. Digestion: Digestive track includes mouth, oesophagus, stomach, intestine and anus. It has two stomachs - The cardiac stomach is where the food is stored, where as the pyloric stomach is where most of the digestion occurs. It churns the food for mechanical digestion and uses digestive glands located either side of the stomach, producing digestive enzymes for chemical digestion. The food then passes through the antennal gland, which is…

learned for some of the other hormones, secretin targets the stomach to make less enzymes and acid, and to make the mixing action slow down. More importantly, though, secretin also causes the liver to make more bile, while causing the pancreas to make bicarbonate ions. Bicarbonate ions are very important for the duodenum because in order for food to be broken down, the stomach has to make lots and lots of hydrochloric acid. The stomach secretes special mucous to help protect it from being…

activity and the autonomic nervous system relays the message from input for the smooth muscle. o Neuropeptides, hormones and neurotransmitters affect gastric emptying • Anatomical controls: o Sphincters: esophageal and stomach  LES, which controls the release of food into the stomach and prevents from reflux • Nitric oxide and VIP inhibit closure of LES • Secondary peristalsis occurs if not all…

Swallowing, which is also known as “deglutition” is the process of transporting a bolus (chewed food) from the mouth, down the esophagus, into the stomach. Deglutition consists of three distinct phases with various neural involvements. For some individuals, the inferior esophageal sphincter can malfunction resulting in gastroesophageal reflux disease (often shortened to GERD). Commonly known as “heartburn,” GERD can affect deglutition as well as a person’s quality of life. GERD can be…

lined with finger-like projections called villi. Villi greatly increase its surface area, and therefore the rate at which absorption can take place. Small intestine delivers chyme to the large intestine. Chyme is food in the stomach that is partly digested and mixed with stomach acids. We know that the small intestine is composed of three layers that is the mucosa, submucosa, muscularis externa, and serosa. Mucosa layer consisting of the lamina propria and stratified squamous or columnar…

It is almost dark. Taj is standing near his fallen prey, a male whitetail deer. He watches it for a while so that he can be sure that the deer is deceased. Because he sees that it is, he does not cut its throat. He looks for a slope so that he can position the deer in such a way that the intestines spill out easily. Not seeing any slopes nearby that he can drag the deer to, he decides to stick with the spot the deer lies. Taj walks over to the deer. He then kneels down, removes his pack, and…

Esophagus. “The oespphagus is a muscular tube, abouto 25cm long with a diameter of 2 cm, which starts at the laryngopharynx and ends at the stomach, and is a passageway for food” (Johnstone, et al, 2014). Chyme is the result of gastric…
