How is bile secretion regulated?
Understand the Problem
The question asks about the regulatory mechanisms that control bile secretion. This involves identifying the hormonal and neural signals that stimulate or inhibit the production and release of bile from the liver and gallbladder.
Answer
Bile secretion is regulated mainly by the hormones cholecystokinin (CCK) and secretin.
Bile secretion is primarily regulated by the hormones cholecystokinin (CCK) and secretin. CCK stimulates gallbladder contraction and relaxation of the sphincter of Oddi, while secretin enhances bicarbonate and water secretion into the bile duct.
Answer for screen readers
Bile secretion is primarily regulated by the hormones cholecystokinin (CCK) and secretin. CCK stimulates gallbladder contraction and relaxation of the sphincter of Oddi, while secretin enhances bicarbonate and water secretion into the bile duct.
More Information
Bile secretion is also influenced by gastrin and somatostatin.
Tips
A common mistake is thinking bile production and secretion are controlled by a single mechanism or hormone. It's a multifaceted process involving several hormones and feedback loops.
