CASE:
Patient HL comes into the clinic with the following symptoms: nausea, vomiting, and diarrhea. The patient has a history of drug abuse and possible Hepatitis C. HL is currently taking the following prescription drugs:
• Synthroid 100 mcg daily
• Nifedipine 30 mg daily
• Prednisone 10 mg daily

Pharmacotherapy for Gastrointestinal and Hepatobiliary Disorders Gastrointestinal (GI) and hepatobiliary disorders affect the structure and function of the GI tract. Many of these disorders often have similar symptoms, such as abdominal pain, cramping, constipation, nausea, bloating, and fatigue. Since multiple disorders can be tied to the same symptoms, it is important for advanced practice nurses to carefully evaluate patients and prescribe a treatment that targets the cause rather than the symptom.

PART A:

Identify the parts of the Digestive System on the diagram overleaf(see Diagram 1)
Explain the function of each part of the Digestive System identified in the diagram above ?
Introduction: The branch of medicine focused on the digestive system is Gastroenterology. The digestive system is a set of organs that work on food and drink to break them down into substances the body can absorb so that our body can grow, repair itself, have energy to live life.

The Digestive system also gets rid of the waste that the body cannot use. Some organs have a direct input into the breakdown of food where others have an indirect input in the breakdown. The digestive system is made up of 2 parts the alimentary canal is made up of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines. In addition to the alimentary canal, there are several important Accessory organs that help your body to digest food they are teeth, tongue, salivary glands, liver, gallbladder, and pancreas.

Mouth is where food and drink enter the body and it has many parts that aid in breaking up the food. The teeth which there is 32 of them made up of incisors canine and molars which cut and tear the food breaking it into smaller pieces (mechanical digestion) the tongue moisten the food with mucus and the saliva glands secrete saliva to help break it up into a pulp and amylase work on starch to break it down.so as the food leaves the mouth to go down the throat(pharynx) it is formed into a bolus or pulp which makes swallowing easier. At the top of the larynx there is a flap called the epiglottis which prevents food going towards the lungs but instead letting into the esophagus. Gastrointestinal and Hepatobiliary Systems Essay
Esophagus or windpipe is a muscular tube connecting the throat to the stomach this foodpipe forces the food down to the stomach using muscular waves called peristalsis and along with mucus from the esophagus. At the end of the esophagus there is the cardiac sphincter that allows the bolus into the stomach but prevents the food going back up the esophagus.
Stomach: It is C shaped bag that hold food until it is ready to go into the small intestine. The stomach release hydrochloric acid which aid digestion but kills bacteria. The stomach mixes and churns the food with the help of the wave like muscles(peristalsis) and enzymes help to chemically break down the food when food leaves the stomach through the pyloric sphincter it is creamy and is called chime.
Small Intestine: It is 7 metre long and it is like a coiled hose and is made up of 3 parts the duodenum, jejunum ileum 90% of the digestion both chemical and mechanical takes place here and some absorption into the bloodstream .The liver produces bile and sends it to the gall bladder and then empties the bile into the duodenum and pancreatic juices are also go into the duodenum in order to help in the breakdown of food. There is villa in the walls of the small intestine which makes absorption into the bloodstream possible.
Large Intestine: is a long, thick tube about 2 ½ inches in diameter and about 5 feet long. It wraps around the small intestine. It has 3 parts – ascending colon, the transverse colon, the descending colon. The large intestine receives undigested food from the small intestine and reabsorbs water back into the bloodstream from the faeces. Some undigested carbohydrates cannot be absorbed and form part of the waste that needs to leave the body. There are bacteria in the large intestine which make important substance called vitamin K. Faeces in the large intestine exit the body through the anal canal.
The liver is the largest gland in the body it is soft and reddish and brown in colour. It is not considered as a direct part of the digestive system. It produces bile that aids in digestion by breaking down material and help creating waste products that will later need to be eliminated
