The Importance of the Liver and the effects of Cirrhosis The liver is known to be the largest organ in the body weighing at about three pounds in adults. It is located in the right upper quadrant area, more specifically in the hypochondriac region beneath the diagram. The liver is one of the most important organs as it performs many metabolic roles. Without it, we would not have the ability to survive. The liver is responsible for performing important functions such as making proteins that aid…

Box jellyfish Nomenclature "Box jellyfish" and "sea wasp" are common names for the highly venomous Chironex fleckeri. However, these terms are ambiguous, as "sea wasp" and "marine stinger" are sometimes used to refer to other jellyfish. Anatomy "Cubomedusae", from Ernst Haeckel's Kunstformen der Natur, 1904 The medusa form of a box jellyfish has a squarish, box-like bell. From each of the four lower corners of this hangs a short pedalium or stalk which bears one or more long, slender, hollow…

obstructions, Peptic ulcers and so on. But one of the most important factors that is related to my topic is drinking too much liquid with meals dilutes the enzymes needed for digestion. The reason behind that is while we eat, our stomachs are producing digestive enzymes and acids such as hydrochloric acid to break down foods. When we drink liquids while we’re eating our food, the acids get diluted and are unable to do break down foods properly. This leads to undigested chunks of food. And you…

In this phase, solid is placed into the mouth and the lips are shut by the orbicularis oris facial muscle (VII). The food is mixed with salvia and masticated with the teeth, so it can pass through the esophagus for digestion. Sensory recognition is critical at this stage and the movement and timing patterns in this phase varies depending on the viscosity. The salvia and food has now created a bolus in which lateral movements of the tongue and mandible are made. Furthermore, the soft palate has…

Syndrome is a rare gastrointestinal disorder. This syndrome can also be known as SMA Syndrome. It is a very rare acquired vascular compression disorder. IN this disorder the Aorta and Superior Mesenteric Artery compress on the intestine causing many digestive issues. The compression is caused when the angle between the two arteries is very low usually 6° to 15° or 2 to 8 mm. The normal angle between these two arteries is between 25° to 60° or 10 to 28 mm. The arteries compress either the second…

the body. Tracing the digestion of a cookie involves a quick trip down your esophagus, a churn in the stomach and a slow, winding movement through the intestines. The Mouth The digestive process begins before the cookie even enters your mouth.Once you take a bite, your teeth initiate the mechanical digestion process.Your teeth smashes the cookie into smaller pieces and your tongue pushes it down your throat( esophagus), but…

subconscious efforts of reactions. The sympathetic division, the parasympathetic division, or collective efforts from both pathways may control a smooth muscle cell. In skeletal muscle, all neural activity is explicitly excitatory. However, the autonomic systems can exert excitatory or inhibitory activation to smooth muscle cells (Stanfield, 5th ed). Contraction or relaxation of a smooth muscle cell relies on where the cell is located. In the gastrointestinal tract, contractions blend the…

Crohn’s disease is defined as a “transmural inflammatory process.”1 Crohn’s disease is one of the two forms of inflammatory bowel disease.2 Crohn’s disease most commonly affects the end of the ileum, which is the last part of the small intestine. Although, it can occur anywhere throughout the entirety of the gastrointestinal tract.1 Typically, there are areas of the gastrointestinal tract that are normal, but these segments are separated by areas of the gastrointestinal tract that have damage.…

Introduction The gastrointestinal tract (GI) comprises of the oral cavity, esophagus, stomach, small intestine, large intestine, rectum, and the anus. Also, digestion process start from the mouth; the ingestion of food stimulate the salivary secretion (mouth), the food is chewed before its passage through the esophagus down to the stomach where mechanical and chemical digestion takes place. Pepsinogen from the chief cells helps with the digestion of protein, amylase from the saliva and…

Pathophysiology of Diverticular Disease Diverticular disease is a condition that most often affects the sigmoid colon and is characterized by a number of small pouches that extend to the surface of the colon. When all four layers of the colon are herniated, it is called a true diverticulum. Typically, diverticula are pseudodiverticula and involve only the mucosa and submucosa (Porth, 2011). The colon could have one diverticulum, or numerous diverticula. The colon’s structure is different from…
