- "Water is absorbed here and the remaining waste material is stored in the rectum as feces before being removed by defecation."
A review of the anatomy and physiology of the large intestine, including the cecum, colon, and rectum, as well as the process of fecal formation and elimination.
Anatomy of the Large Intestine: This topic covers the structure and shape of the large intestine, including its various parts such as the cecum, colon, rectum, and anal canal.
Functions of the Large Intestine: In this topic, learners study the various roles of the large intestine, such as absorption of water and electrolytes, fermentation, and storage of feces.
Gut Microbiome: This topic covers the microorganisms living in the large intestine, including their role in digestion, immune function, and overall health.
Digestive Motility: Learners study how the large intestine propels food through the various regions, including the haustral contractions, mass movements, and defecation reflex.
Disorders of the Large Intestine: In this topic, students learn about clinical conditions that affect the large intestine, including inflammatory bowel disease, diverticulitis, and colorectal cancer.
Nutrition and Large Intestine Health: This topic covers the importance of a balanced diet in maintaining a healthy large intestine; how fiber, fats, and other nutrients affect gut function.
Diagnostic Procedures: Learners study diagnostic procedures used to diagnose disorders of the large intestine, such as colonoscopy, sigmoidoscopy, and barium enema.
Treatment Options: In this topic, learners study various treatment options for disorders of the large intestine, including dietary changes, medication, and surgery.
Aging and the Large Intestine: This topic covers how the large intestine changes as we age, including increased risk of certain disorders and decreased motility.
Comparative Anatomy of the Large Intestine: In this topic, students compare and contrast the structure and function of the large intestines in different animals, including herbivores and carnivores.
Cecum: The first part of the large intestine and the location of the appendix.
Ascending Colon: The portion of the colon that runs upward on the right side of the body.
Transverse Colon: The part of the colon that runs across the abdomen from right to left.
Descending Colon: The portion of the colon that runs downward on the left side of the body.
Sigmoid Colon: The S-shaped part of the colon that connects to the rectum.
Rectum: The final part of the large intestine that stores feces before they are eliminated through the anus.
