Pre assessment Homeostasis

Front

What is homeostasis?

Back

Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

Front

What role do feedback mechanisms play in homeostasis?

Back

Feedback mechanisms are processes that help regulate physiological functions by detecting changes and initiating responses to restore balance.

Front

What are white blood cells?

Back

White blood cells are a key component of the immune system, responsible for defending the body against infections and foreign invaders.

Front

What is the function of hormones in the body?

Back

Hormones are chemical messengers that regulate various physiological processes, including growth, metabolism, and homeostasis.

Front

What is an immune response?

Back

An immune response is the body's defense mechanism against pathogens, involving the activation of white blood cells and the production of antibodies.

Front

What is an allergic reaction?

Back

An allergic reaction occurs when the immune system overreacts to a usually harmless substance, leading to symptoms like itching, swelling, or difficulty breathing.

Front

What is the significance of specialized receptor molecules on cells?

Back

Specialized receptor molecules on cells allow them to detect and respond to specific hormones, facilitating communication and regulation within the body.

Front

What is the main function of the endocrine system?

Back

The endocrine system's main function is to produce and secrete hormones that regulate various bodily functions, including growth, metabolism, and mood.

Front

What is the difference between antibodies and antigens?

Back

Antibodies are proteins produced by the immune system to identify and neutralize foreign objects like bacteria and viruses, while antigens are substances that trigger an immune response.

Front

What is the role of feedback loops in regulating blood sugar levels?

Back

Feedback loops help maintain blood sugar levels by signaling the pancreas to release insulin or glucagon in response to changes in blood glucose.
