Homeostasis - Living Environment

Front

What is homeostasis?

Back

Homeostasis is the ability of an organism to maintain a relatively stable internal environment despite changes in external conditions.

Front

What system is responsible for providing oxygen to cells?

Back

The circulatory system.

Front

What is thermoregulation?

Back

Thermoregulation is the process by which an organism maintains its internal temperature within a certain range.

Front

Which organelle is responsible for releasing energy stored in food?

Back

Mitochondria.

Front

What is the role of the respiratory system in homeostasis?

Back

The respiratory system helps maintain homeostasis by facilitating gas exchange, providing oxygen to the blood and removing carbon dioxide.

Front

What is a feedback regulation in homeostasis?

Back

Feedback regulation is a process where the output of a system influences its own operation, often through negative feedback to maintain stability.

Front

What does it mean when we say homeostasis incorporates feedback mechanisms?

Back

It means that the body uses feedback loops to adjust physiological processes to maintain balance.

Front

What is the difference between positive and negative feedback in homeostasis?

Back

Negative feedback reduces the output of a system to return to a set point, while positive feedback amplifies responses to push the system away from its starting state.

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 significance of maintaining pH levels in the body?

Back

Maintaining pH levels is crucial for enzyme function and overall metabolic processes.
