THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The duodenum is the shortest section, on average measuring from 20 cm to 25 cm in length. Its proximal end is connected to the antrum of the stomach, separated by the pylorus, and the distal end blends into the beginning of the jejunum.

Detailed explanation-2: -The duodenum is the first part of the small intestine that the stomach feeds into. It’s a short, descending chute (about 10 inches long) that curves around the pancreas in a “C” shape before connecting to the rest of the coiled intestines.

Detailed explanation-3: -Ileum: This last section is the longest part of your small intestine. The ileum is where most of the nutrients from your food are absorbed before emptying into the large intestine.

Detailed explanation-4: -The small and large intestines are a vital part of the human digestive system. The length of the small intestine is roughly 9–16 feet (ft), while the large intestine is shorter, measuring about 5 ft long. The intestines sit in the abdomen and absorb nutrients, vitamins, and water.
