Introduction:
Secretin refers to the hormone which basically regulates the homeostasis of the water in the entire body and also has influenced the environment of the duodenum. It basically refers to the peptide hormone which releases the S cells of the duodenum that is situated in the intestinal glands.
Answer to Problem 1TYK
Correct answer:
The environment of the duodenum is regulated by secretin hormone which stimulates the secretions.
Explanation of Solution
Explanation for the correct answer:
Option (a) is given as secretion of bicarbonate from the pancreas. Secretin is a hormone which basically works like a fireman and it is responsible for stimulating the pancreas and bile ducts which helps in the production of the flood of bicarbonate base that mainly neutralizes the acid. Therefore, option (a) is a correct answer.
Explanation for the incorrect answer:
Option (b) is given as secretion of hydrochloric acid from the stomach epithelium. Secretin hormone basically neutralizes the HCl acid. So, it is an incorrect answer.
Option (c) is given as secretion of digestive enzymes from the pancreas. It is responsible for stimulating the bicarbonate base which is released by the pancreas and not the digestive enzymes. So, it is an incorrect answer.
Option (d) is given as uptake of glucose from the bloodstream by the cells in the entire body. Glucose is not stimulated by the secretin. So, it is an incorrect answer.
Hence, options (b), (c), and (d) are incorrect.
Therefore, it can be concluded that the secretin stimulates the bicarbonate base which is released from the pancreas.
