Homeostasis and Its Functions

These flashcards cover the key concepts related to homeostasis, its definition, examples of conditions it regulates in the body, and its importance in physiological processes.

What is homeostasis?

Homeostasis is the maintenance of a constant internal environment to ensure optimum conditions for enzyme and cellular function.

What conditions does homeostasis maintain in the body?

Homeostasis maintains conditions such as blood glucose concentration, body temperature, and water levels.

Which process ensures optimal enzyme function in the body?

Homeostasis ensures optimal enzyme function.

Why is temperature regulation important in homeostasis?

Temperature regulation is crucial for maintaining enzyme activity and overall cellular function.

What role does blood glucose concentration play in homeostasis?

Blood glucose concentration is vital for providing energy to cells and maintaining overall metabolic function.

How does the body respond to high blood glucose levels?

The body responds by releasing insulin to lower blood glucose levels.

What happens when body temperature rises above normal?

When body temperature rises, mechanisms like sweating help cool the body down.

What is one method the body uses to regulate water levels?

The body regulates water levels through mechanisms like urine concentration and thirst response.

What can disturb homeostasis?

Factors such as illness, extreme temperatures, and dehydration can disturb homeostasis.

Why is maintaining a stable internal environment crucial?

A stable internal environment is essential for the proper functioning of cells and enzymes.

What is the significance of water levels in homeostasis?

Water levels are significant for maintaining cellular processes and overall health.

Can homeostasis be disrupted? If so, how?

Yes, homeostasis can be disrupted by factors like stress, illness, and environmental changes.

What is the relationship between enzyme function and homeostasis?

Enzyme function depends on stable conditions maintained by homeostasis.

What does 'optimum conditions' refer to in the context of enzymes?

Optimum conditions refer to the ideal temperature, pH, and concentration levels for enzyme activity.

How do feedback systems relate to homeostasis?

Feedback systems, such as negative feedback, help maintain homeostasis by regulating physiological processes.
