What main anatomical parts are included in a right hemicolectomy?

A right hemicolectomy involves the surgical removal of the right portion of the colon, which primarily includes the cecum and the ascending colon. This procedure is typically performed to treat conditions such as colon cancer, diverticulitis, or inflammatory bowel disease that affect this portion of the colon.

The cecum is the beginning section of the large intestine that connects to the small intestine, while the ascending colon runs upward on the right side of the abdomen. Therefore, option B correctly identifies these anatomical structures that are involved in a right hemicolectomy. The surgical procedure usually includes resection of these parts with a reconnection to the remaining segments of the colon or the ileum, depending on the extent of the surgery and the patient's condition.

Other choices, while mentioning parts of the colon, do not accurately reflect the correct anatomy involved in a right hemicolectomy. Thus, understanding the correct anatomical structures is crucial for comprehending the implications of such surgical procedures in medical practice.
