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 is negative feedback in homeostasis?

Back

Negative feedback is a mechanism that counteracts a change in a physiological variable, returning it to its set point.

Front

What is a set point in homeostasis?

Back

A set point is the ideal value or range of a physiological variable that the body tries to maintain.

Front

What is the main function of cellular respiration?

Back

The main function of cellular respiration is to convert glucose into energy (ATP) for cellular activities.

Front

What is muscle fatigue?

Back

Muscle fatigue is a decrease in muscle performance due to prolonged activity, often resulting in reduced strength and endurance.

Front

What role does insulin play in blood glucose regulation?

Back

Insulin helps cells absorb glucose from the bloodstream, lowering blood sugar levels.

Front

What happens when blood sugar levels are too high?

Back

When blood sugar levels are too high, the pancreas releases insulin to help lower the glucose concentration in the blood.

Front

What is the role of the liver in glucose regulation?

Back

The liver stores and releases glucose as needed to help maintain stable blood sugar levels.

Front

What is the significance of thermoregulation in homeostasis?

Back

Thermoregulation is the process of maintaining an optimal body temperature, which is crucial for proper enzyme function and metabolic processes.

Front

What is the role of feedback mechanisms in homeostasis?

Back

Feedback mechanisms, including negative and positive feedback, help regulate physiological processes to maintain homeostasis.
