Answer 1

Answer: (C)

Last part of the small intestine

The small intestine is the most important part of the digestive system where digestion and absorption of nutrients take place. The small intestine can be divided into 3 major regions. The first part is duodenum that connects the pyloric sphincter of the stomach. It is the shortest region of the small intestine, measuring only about 10 inches in length. The second part is the jejunum that serves as the primary site of nutrient absorption. It measures around 3 feet in length. The last part of small intestine is the ileum that is about 6 feet long and completes the absorption of nutrients that were missed in the jejunum

So, the correct answer is 'Last part of the small intestine'
