*01/10/25 (R) Lab Flashcard - Homeostasis & Heart Rate

Front

What is homeostasis?

Back

Homeostasis is the maintenance of a relatively stable internal environment in the body despite changes in external conditions.

Front

What happens to your heart rate during exercise?

Back

Your heart rate increases during exercise to supply more oxygen to the muscles.

Front

What is the role of sweating in regulating body temperature?

Back

Sweating helps cool the body down by evaporating heat from the skin.

Front

What is metabolism?

Back

Metabolism is the set of life-sustaining chemical reactions in organisms that convert food into energy.

Front

What is the significance of increased oxygen demand during exercise?

Back

Increased oxygen demand during exercise is necessary for energy production in muscles.

Front

What does excretion refer to in the context of homeostasis?

Back

Excretion is the process of removing waste products from the body to maintain internal balance.

Front

How does the body respond to overheating?

Back

The body responds to overheating by sweating and increasing blood flow to the skin.

Front

What is the relationship between exercise and body temperature?

Back

Exercise increases body temperature due to increased metabolic activity.

Front

What is the effect of dehydration on homeostasis?

Back

Dehydration disrupts homeostasis by affecting blood volume and concentration of electrolytes.

Front

What is the role of the heart in maintaining homeostasis?

Back

The heart pumps blood to transport oxygen, nutrients, and hormones, helping to maintain homeostasis.
