Gastric Disease: Causation and Preventative Management Strategies Equine Gastric Ulcer Syndrome (EGUS) has been used to describe a wide variety of ulcerative diseases in the horses. These ulcers can be commonly found in the esophageal, stomach, and duodenum mucosa of horses and occurs frequently because horses are subjected to human management practices that are not always based on their natural inclinations, such as stabling and being ridden and used for heavy work. EGUS is an umbrella term…

1) What is a difference between endotherms and ectotherms? The difference between an endotherm and an ectotherm is how their body is composed for regulating body temperature. This is important, as body temperature is key to maintain homeostasis. While ectotherms must rely on outside variables to regulate body temperature endotherms can regulate body temperature using mechanism within their own body. A major adaptation in endothermic organisms that is not seen in ectotherms is the large number…

most abundant lipids in the diet and phospholipids. Lingual lipase secreted by glands in the tongue and gastric lipase secreted by gastric chief cells hydrolyze a small amount of triglycerides into fatty acids and monoglycerides. As chyme enters the duodenum from the stomach cholecytokinin stimulates the secretion of bile salts and pancreatic juice. Bile salts synthesized in the liver, and stored in the gallbladder, is released clinging to mono, di, and triglycerides of fat globules, causing the…

Bacteria They are formed by a single rudimentary cell. They have no nucleus or plastids, but chromatin. Some have assimilators pigments. They are on earth, water, and air, and can generally move. They may be causing disease and therefore are called pathogens. Those that do not cause disease are called saprophytes. In some cases, they are even useful, as in digestive processes or synthesis of vitamins. By the way, they are called coconuts when circular; bacilli if they have the form of rods;…

Antiemetics Overview: Antiemetics are used for nausea and to prevent vomiting and also used for motion sickness. These drugs can be bought over the counter. (OTC) Action: Dimenhydrenate or Dramamine is an antihistamine. It should be taken one hour before travelling, and will prevent motion sickness. The antihistamine is available in children’s liquid formula and in a Less Drowsy Formula that may have fewer sedative side effects. Meclizine hydrochloride (Bonine) treats vomiting and dizziness…

experiment will be chymotrypsin which falls under the category of serine proteases. Chymotrypsin has been discovered as a digestive enzyme found in pancreatic secretions of animals, whose main function is said to be hydrolysis of peptides that enter the duodenum of the small intestine. As can be determined from its enzyme class, it has an active serine residue which is used to hydrolyze aromatic amino acids such as Phenylalanine, Tyrosine or Tryptophan at their C-terminus. The hydrophobic…

Morrison (2012) explains that nurses have specialised knowledge to gather comprehensive physical assessments and differential diagnoses. Evidence-based practice utilises the best available evidence and clinician expertise to formulise an evidence based decision (Bickley, 2013). This essay will analyse the diagnostic reasoning behind decisions made in the diagnosis of a client. A brief diagnosis and pathophysiology will be explained, followed by the client’s health history, physical examination…

After being lifted from the plate and placed in the mouth, the poor pizza goes on a long journey through the digestive system and eventually is turned into waste after passing through the 6 primary organs of the digestive tract: the mouth, oesophagus, stomach, small intestine, large intestine and anus. The process of digestion starts when Bob the pizza is placed in the mouth. The main structures of the mouth are the teeth, tongue, salivary duct and oesophagus. Bob is killed, being chewed on by…

the nurse to decide which organs or structures may be involved. Figure 2 shows the location of some of these organs or structures. The structures located within the right upper quadrant are: right lobe of the hver; gall bladder; head of pancreas; duodenum; sections of the ascending and transverse colon. The structures located within the left upper quadrant are: left lobe of the liver; stomach; FIGURE 1 The four abdominal…
