Digestive system

Gastrointestinal System The digestive system is a group of organs working together to convert food into energy, and basic nutrients to feed the entire body. Food passes through a long tube in the body called the gastrointestinal tract (GI), also known as the alimentary canal. The gastrointestinal tract comprises of the oral cavity, pharynx, oesophagus, stomach, small intestines, and large intestines. For the body to be able to receive energy and nutrients from food, six major functions take…

Open Small Bowel Resection Small bowel resection is surgery to remove part of the small bowel. The small bowel, also called the small intestine, is the top part of the intestines. It is part of the digestive system. When food leaves the stomach, it goes into the small bowel. Most food is then absorbed into the body. A small bowel resection may be needed if the small bowel becomes blocked or harmed by disease. One type of procedure is called an open resection. This means the surgeon will make…

OF NURSING HISTORY AS PART OF GASTROINTESTINAL TRACT ASSESSMENT. This concept is taken from Block 4, Module 8 which is entitled as ‘Assessment of gastrointestinal system’. The digestive system is made up of organs that function together to transform food substances to energy and nutrients that are needed in the body. The digestive system is made up of the alimentary canal which include the mouth or oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines including the…

Dear Sir or Madam, Situated in the abdomen of vertebrates, and involved in many metabolic processes, I for one Liver, remain the second-largest organ. I perform numerous processes assisting with digestion, metabolism, immunity, including the storage of nutrients. I’m a glandular organ divided by openings. I operate in the emission of bile (Greenish liquid that responsible for chemical digestion of fats if your unaware) along with numerous metabolic processes. These processes are essential for…

isn’t hard to break apart in the stomach unless consumed in very large quantities due to its sticky texture. In many incidents, swallowed gum passes through the digestive system as well as any other food. When somebody swallows gum the material is first taken down the esophagus (the first mushed food is called bolus in the digestive system) where mechanical breakdown occurs in the mouth. It is it then carried to the stomach through the action of peristalsis (a wavelike motion) so the substance…

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 is critical for the phases that follow and…

Propels food along the digestive tract, responsible for contractions of GI tract, regulates mobility of GI tract. The muscularis externa of the stomach is modified because other muscularis externa is composed of two layers: the inner circular layer and the outer longitudinal layer. However, the muscularis externa of the stomach contains a third innermost oblique layer. This third innermost oblique layer relates to the function of the stomach because it is the smooth muscle that is responsible…

The Gastrointestinal System The gastrointestinal tract is a collection of organs that work together to enable the body to digest and absorb numerous substances. It is often described as a long muscular tube starting at the mouth, and ending at the anus. The esophagus, stomach, small intestine (consisting of the duodenum, jejunum, and the ileum), and the large intestine (consisting of the cecum, ascending, transverse, and descending colon, the sigmoid, rectum, and anus), all make up the…

The mouth which is also called the oral cavity is associated with the accessory organs such as teeth, salivary glands, and tongue. The mouth is where digestion starts. Our teeth are used to chew food into really small pieces and our saliva contains enzymes that begins the process of digestion. Our tongue occupies the floor of the mouth and mixes food with saliva to form bolus which is a compact mass that forms food into a lump that helps initiates swallowing. The mouth begins the process of…

Gastro Intestinal cancer also known as GI affects the digestive system. The function of the GI is a pathway food takes through the very first point which is the mouth then makes its way through the esophagus, stomach, small and large intestine and then the rectum to evacuate. According to Lauren Peirce Carcas gastric cancer remains the fourth most common type of cancer and is the second leading cause of cancer-related death worldwide. GI cancer is very serious and should be treated as soon as…
