  • Two Types Of Physical Digestion And Physical Digestion

    The small intestine can be found between the stomach and the large stomach. It is made up of three regions namely; duodenum, jejunum and ileum. The duodenum which is the longest part and measures about ten to twelve feet breaks down the food whilst the jejunum (about four feet) and ileum (about five feet long) work together to absorb nutrients and send them into the bloodstream. The liver is an important organ which sits on the right side of the stomach. The liver is said to weigh about 3…

  • Effects Of Digestion

    Digestion works well when all the reactions along the way are functioning at an optimum but when one is compromised it eventually impacts on the entire tract. This is evident when there is Hypochlorhydria or low stomach acid. When there is a depletion of hydrochloric acid (HCL) the entire digestive process is affected, from mechanical and chemical digestions to absorption of nutrients. The stomach secrets HCL which maintains the low pH (between 1.5- 3) during the gastric phase of digestion. This…

  • The Digestive System: The Function Of The Digestive System

    Those eight sections are the oral cavity/ tongue, the esophagus, the stomach, the small intestine, the large intestine, the liver, the pancreas, the gallbladder, the rectum, and lastly the anus. Our first stop is the oral cavity or the mouth. The food is taken into the digestive system by the mouth. The mouth itself contains many organs, such as the teeth, the tongue, and the salivary glands. When food enters the mouth it must first be broken down by the enzymes inside your mouth. These organs…

  • Gastric Secretion Essay

    Normal pathophysiology of gastric acid stimulation and production. Normally the stomach holds around 50cc of fluid. There are several stimuli that work together in the complex process of the digestion process (Huether & McCance, 2012). There are three phases of gastric secretion, first being the cephalic phase, which is stimulated by the thoughts , smells and taste of food. Stimulation releases acetylcholine and the release of gastrin-releasing peptide, thus indirectly stimulates hydrogen ions.…

  • Digestion Essay

    This opening allows chyme to enter into the small intestine. The small intestine is composed of 3 parts: duodenum, jejunum and ileum. The duodenum is the only part of the small intestine that continues to break down food with the release of bile. While the stomach releases hydrochloric acid and creates an acidic environment with a low pH, the duodenum is slightly basic with a higher pH. Bile, which is produced in the liver and stored in large quantities in the gall bladder, is released to…

  • The Negative Effects Of Alzheimer's Disease

    - What is the issue being addressed? When food is swallowed it enters oesophagus – carrying food from the mouth to the stomach for further digestion. Contractions called peristalsis push the food down the oesophagus through a muscular valve called the lower oesophageal sphincter (LES) and into the stomach. The digestive juices secreted by the stomach are highly acidic. When the stomach contracts to move the food into the intestine the LES closes tightly in order to prevent these acidic juices…

  • The Gastrointestive System: The Digestive System

    located right between the mouth and esophagus, which is a narrow muscular tube that leads to the stomach. Gylys and Wedding (2013, p 122) stated, “that the pharynx serves as a passageway to the respiratory and GI tract and provides a resonating chamber for speech sounds.” In order to keep the respiratory tract free from food particles that pass into the esophagus there is a flap of connective tissue called the epiglottis that shuts the trachea off when we are swallowing to prevent choking.…

  • Peristalsis Essay

    Food is compressed and mixed with gastric juices and enzymes such as pepsin coming from the gastric mucosa and is physically turned into chyme. Peristalis starts near the gastroesophageal sphincter causing the stomach wall to ripple. Small amounts of chyme filter through the pyloric valve via a back and forth pumping action. Depending on the size and contents of the meal the stomach empties chyme into the duodenum within four to six hours. As chyme enters the duodenum, receptors in the wall…
