What is homeostasis in humans and how does the regulation of glucose levels occur in the internal environment?
Understand the Problem
The question appears to be focused on the process of homeostasis in humans, particularly concerning the regulation of glucose levels in the blood and the sequence of events in a negative feedback mechanism related to that regulation.
Answer
Homeostasis maintains stable internal conditions. Insulin and glucagon regulate glucose levels through negative feedback.
Homeostasis in humans refers to maintaining a stable internal environment. The regulation of glucose levels is controlled by insulin and glucagon. When glucose levels rise, insulin is secreted by the pancreas to promote the conversion of glucose to glycogen in the liver, decreasing blood glucose levels. If glucose levels fall, glucagon promotes glycogen conversion back to glucose, increasing blood glucose levels.
Answer for screen readers
Homeostasis in humans refers to maintaining a stable internal environment. The regulation of glucose levels is controlled by insulin and glucagon. When glucose levels rise, insulin is secreted by the pancreas to promote the conversion of glucose to glycogen in the liver, decreasing blood glucose levels. If glucose levels fall, glucagon promotes glycogen conversion back to glucose, increasing blood glucose levels.
More Information
Homeostasis allows the body to adjust to changes in external conditions while keeping internal conditions stable, essential for survival.
Tips
A common mistake is thinking insulin directly reduces blood sugar without the liver's role in converting glucose to glycogen.
