Summary

study the digestion system relating to organs and anatomy of the Upper and lower GI tract....

Description

1.

Provide a detailed description of the path of chyme, and later feces, from the duodenum to the anus, identifying the different portions of the small and large intestines. According to (NIDDK.nih.gov, 2017) Stomach. After food enters your stomach, the stomach muscles mix the food and liquid with digestive juices. The stomach slowly empties its contents, called chyme, into your small intestine. The duodenum is the first part of the small intestine Small intestine. The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream. As peristalsis continues, the waste products of the digestive process move into the large intestine. Large intestine. Waste products from the digestive process include undigested parts of food, fluid, and older cells from the lining of your GI tract. The large intestine absorbs water and changes the waste from liquid into stool. Peristalsis helps move the stool into your rectum. Rectum. The lower end of your large intestine, the rectum, stores stool until it pushes stool out of your anus during a bowel movement.

2.

Describe 2 important functions of the small intestine. The small intestine breaks down food from the stomach and absorbs much of the nutrients from the food. (Secretion and absorption)

3.

Describe 2 important functions of the large intestine. Bile synthesis and Carbohydrates, lipids, proteins metabolism

4.

Diverticulitis most often affects the sigmoid colon. Based on your knowledge of its location in the abdomen in which of the following quadrants do you predict the location of pain to be? Lower left quadrant ( but on the right in Asians)

5.

If diverticulitis worsens it can lead to life-threatening peritonitis. Describe 2 functions of the peritoneum. The peritoneum serves to support the organs of the abdomen and acts as a conduit for the passage of nerves, blood vessels, and lymphatic’s. Although the peritoneum is thin, it is made of 2 layers with a potential space between them. The potential space between the 2 layers contains about 50 to 100 ml of serous fluid that prevents friction and allows the layers and organs to glide freely. (Kalra et al., 2020)
