Question
Our body naturally wants to be in a state of homeostasis, where internal conditions and systems are stable. We respond to external conditions by using feedback mechanisms to maintain stability—most commonly negative feedback loops.
An example of our body using negative feedback loops to maintain equilibrium is blood sugar homeostasis. Blood sugar, or blood glucose, is the main sugar found in our blood; it’s our bodies’ primary source of energy. Most of our blood sugar comes from the food that we eat. So when we consume foods, like carbohydrates, our blood sugar levels rise. The pancreas detects this change and releases insulin into the bloodstream. Insulin helps move the glucose from our blood into our cells so it can be used for energy. As a result, our blood sugar levels decrease to our body’s preferred set point.
Which of the following triggers the release of insulin into the bloodstream?
A
High blood sugar levels
B
Low blood flow rate
C
Increased blood oxygen levels
D
Decreased glucose levels

The correct answer is:
A - High blood sugar levels
High blood sugar levels trigger the pancreas to release insulin into the bloodstream, which helps lower blood sugar levels by facilitating the uptake of glucose into cells.
