Multiple Choice

Which of the following best describes the concept of homeostasis in the human body?

The mechanism by which the body increases its temperature in response to cold weather.

The process of the body adapting to new environments by altering its genetic code.

The body's response to external stimuli by producing adrenaline.

The body's ability to maintain a stable internal environment despite changes in external conditions.

Verified step by step guidance

Homeostasis refers to the body's ability to maintain a stable internal environment, which is crucial for optimal functioning.

The concept involves various physiological processes that regulate factors such as temperature, pH, and electrolyte balance.

When external conditions change, the body uses feedback mechanisms to adjust and stabilize internal conditions.

For example, if the external temperature drops, the body may initiate shivering to generate heat and maintain core temperature.

Homeostasis is essential for survival, as it ensures that the body's internal environment remains within narrow limits despite external fluctuations.
