Digestion of carbohydrates, proteins, and fats occurs here as well as absorption of nutrients
A
Cecum
B
Large intestines
C
Small intestines
D
Stomach
Explanation: 

Detailed explanation-1: -Carbohydrates, proteins, and fats are digested in the intestine, where they are broken down into their basic units: Carbohydrates into sugars. Proteins into amino acids. Fats into fatty acids and glycerol.

Detailed explanation-2: -Amylase, maltase, and lactase in the mouth digest carbohydrates. Trypsin and lipase in the stomach digest protein. Bile emulsifies lipids in the small intestine.

Detailed explanation-3: -The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream.

Detailed explanation-4: -Jejunum. The jejunum is the middle part of the small intestine, between the duodenum and ileum. Most digestion and nutrient absorption takes place in the jejunum.

Detailed explanation-5: -Most carbohydrate digestion occurs in the small intestine, thanks to a suite of enzymes. Pancreatic amylase is secreted from the pancreas into the small intestine, and like salivary amylase, it breaks starch down to small oligosaccharides (containing 3 to 10 glucose molecules) and maltose.
