Question

Most chemical digestion occurs here

a. large intestine
b. jejunum
c. duodenum
d. stomach
e. ileum

Answer 1

Most chemical digestion occurs in the duodenum, which is the first section of the small intestine. This is followed by the jejunum and ileum, which mainly absorb the digested nutrients.

Step-by-step explanation:

The majority of chemical digestion occurs in the small intestine, specifically within the duodenum, which is the first and shortest section of the small intestine. The duodenum is where enzymes released from the pancreas and bile from the liver act to digest food. The next parts of the small intestine, the jejunum and ileum, are mainly responsible for absorption of nutrients after the process of chemical digestion has largely occurred in the duodenum.

The jejunum is where most carbohydrates and amino acids are absorbed after digestion, while the ileum primarily absorbs bile salts and certain vitamins. Therefore, the best answer to the question, 'Most chemical digestion occurs here,' is c. duodenum.

Answer 2

Answer: Duodenum

Explanation:

Human body needs food to work efficiently. The food that is ingested by mouth is broken down into smaller components.

These smaller components are absorbed and energy is obtained from them. The digestion of takes place by the mechanical and chemical digestion.

Most of chemicals are secreted from the pancreas, liver and small intestine into the duodenum where maximum chemical digestion takes place.

Hence, the correct answer is duodenum.
