The correct answer is B. Large Intestine.
The colon and rectum are part of the large intestine, which is the lower part of the digestive system. The large intestine is about 5 feet long and is responsible for absorbing water and nutrients from food, as well as storing waste products until they are eliminated from the body.
The small intestine is the first part of the digestive system. It is about 20 feet long and is responsible for absorbing most of the nutrients from food. The stomach is a muscular sac that stores food and helps to break it down. The ureter is a tube that carries urine from the kidneys to the bladder.
The colon is divided into four parts: the ascending colon, the transverse colon, the descending colon, and the sigmoid colon. The rectum is the last part of the large intestine and is about 6 inches long. It connects the colon to the anus, which is the opening through which waste products are eliminated from the body.
The colon and rectum are important organs that play a vital role in digestion and elimination.
