Homeostasis

Which is true about homeostasis?

• Homeostasis is the process of keeping the body temperature exact.

• Homeostasis is the process of maintaining a balanced diet.
• Homeostasis is the process of preventing diseases within the body.
• Homeostasis is the process of maintaining a stable internal environment within the body.

An environmental stressor can at most effect homeostasis of how many different things at the same time?

• multiple
• none
• one
• two

How does shivering effect the body's internal temperature?

• Shivering generates heat through muscle contractions.
• Shivering has no effect on the body's temperature.
• Shivering causes the body to sweat, which warms it up.
• Shivering cools down the body by releasing heat.

How can humidity effect the body's ability to maintain a steady internal temperature?

• Humidity makes it harder for sweat to evaporate, leading to an increase in body temperature.
• Humidity causes the body to release excess heat, leading to a decrease in body temperature.
• Humidity causes the body to produce less sweat, resulting in a decrease in body temperature.
• Humidity has no effect on the body's ability to maintain a steady internal temperature.

vasoconstriction and vasodilation play an important part in the body maintain a steady internal temperature, what do these terms mean?

• Vasoconstriction and vasodilation refer to the narrowing and widening of blood vessels, respectively, to regulate body temperature.
• Vasoconstriction and vasodilation refer to the expansion and contraction of blood vessels, respectively, to regulate body temperature.
• Vasoconstriction and vasodilation refer to the movement of blood from the heart to the rest of the body, respectively, to regulate body temperature.
• Vasoconstriction and vasodilation refer to the production and breakdown of heat in the body, respectively, to regulate body temperature.

What is the body's standard internal temperature, that your body tries to maintain?

• The body's standard internal temperature that your body tries to maintain is approximately 98.6 degrees Fahrenheit or 37 degrees Celsius.
• The body's standard internal temperature that your body tries to maintain is approximately 104 degrees Fahrenheit or 40 degrees Celsius.
• The body's standard internal temperature that your body tries to maintain is approximately 95 degrees Fahrenheit or 35 degrees Celsius.
• The body's standard internal temperature that your body tries to maintain is approximately 100 degrees Fahrenheit or 38 degrees Celsius.

Why is homeostasis important?

• To maintain a stable internal environment in the body.
• To disrupt the body's internal environment.
• To create an unstable internal environment in the body.
• To promote disease and illness in the body.

What does the body do to maintain homostasis during exercise?

• The body increases heart rate, breathing rate, and blood flow to deliver oxygen and nutrients to the muscles, and regulates body temperature through sweating and dilation of blood vessels.
• The body decreases heart rate, breathing rate, and blood flow to conserve energy during exercise.
• The body stops sweating and constricts blood vessels to regulate body temperature during exercise.
• The body decreases heart rate and breathing rate to prevent oxygen and nutrient delivery to the muscles during exercise.
