Homeostasis and Feedback Loops Flashcardizz

Front

What is Homeostasis?

Back

Homeostasis is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation.

What happens when glucose levels in the blood rise?

Back

When glucose levels rise, the brain signals the pancreas to release insulin, allowing glucose to enter cells and lower blood sugar levels. This is an example of a Negative Feedback Loop.

Front

What is the body's response to cold environments?

Back

In cold environments, the body shivers to increase body temperature.

Front

What is an example of a Negative Feedback Loop?

Back

Blood glucose regulation, Temperature regulation, and Heart rate regulation are all examples of Negative Feedback Loops.

Front

Define a Positive Feedback Loop.

Back

A Positive Feedback Loop amplifies a response or process, leading to an increase in the output.

Front

What role does insulin play in blood sugar regulation?

Back

Insulin helps lower blood sugar levels by facilitating the entry of glucose into cells.

Front

What is the significance of feedback loops in homeostasis?

Back

Feedback loops are crucial for maintaining homeostasis by regulating physiological processes.

Front

How does the body respond to overheating?

Back

The body responds to overheating by sweating and increasing blood flow to the skin to dissipate heat.

Front

What is the difference between negative and positive feedback loops?

Back

Negative feedback loops reduce the output of a process, while positive feedback loops enhance it.
