    Study Notes

    • The large intestine is a major component of the gastrointestinal tract, with a length of approximately 5 meters (6 feet) and a diameter of 2.5 inches

    • The large intestine is composed of four parts: the cecum and appendix, the colon, the rectum, and the anus

    • The cecum is the widest portion of the large intestine, located in the right lower quadrant of the abdomen, and attached to it is the appendix, which varies in position and length

    • The ileocecal valve, located at the junction of the ileum and the cecum, acts as a sphincter to prevent reflux from the cecum to the ileum

    • The rectum is the last 12 cm of the large intestine, anterior to the sacrum and coccyx, and consists of two anterioposterior curves; the anal canal, which is the last 3 cm of the large intestine, is controlled by both involuntary and voluntary muscles

    • The large intestine has a greater internal diameter than the small intestine, and contains haustra due to the Taeniae coli muscle

    • In radiographic anatomy, the air-barium locations in the large intestine differ depending on the position of the patient; for example, in the supine position, air is present in the transverse colon and loops of the sigmoid colon, while barium fills the ascending, descending, and parts of the sigmoid colon

    • The radiographic procedures used to examine the large intestine include small bowel series, barium enema, and enteroclysis, which vary in their indications, contraindications, and techniques for patient preparation and imaging.
