Question

In this activity, it’s up to you, not the body, to maintain homeostasis in a virtual person. Gauges show current conditions in the body. To achieve homeostasis, click the left or right arrows to adjust heart rate, respiration, blood vessel dilation, perspiration, or blood sugar hormone release.

Your goal is to keep the dials centered. Click the button for each body system feature to learn more about that body system.

Don‘t become complacent when you achieve a balance! Our person will randomly change states and display a new set of conditions.

You will complete the homeostasis activity three time, then answer questions about your experiments.

Question 1
Which body systems can you control in this activity for the virtual person? Select all that apply(5 points)

Answer 1

In the activity you described, the body systems that you can control for the virtual person include:

1. Pulse
2. Blood Delivery
3. Body Temperature
4. Glucose

These systems relate to maintaining homeostasis in the body. "Oxygen Need," "Food Intake," "Blood Pressure," and "Sleep" are likely not directly adjustable options in this particular activity based on your description. So, the correct responses are:

- Pulse
- Blood Delivery
- Body Temperature
- Glucose

Answer 2

What happens to the rate of blood delivery if your heart rate increases?(1 point)
Responses

Blood delivery rate decreases
Blood delivery rate decreases

It has no impact on blood delivery rate
It has no impact on blood delivery rate

Blood delivery rate increases

Answer 3

If your heart rate increases, the blood delivery rate typically increases as well. This is because a higher heart rate means that the heart is pumping more blood in a given amount of time, which enhances circulation and blood flow throughout the body.

So, the correct response is:

- Blood delivery rate increases.

Answer 4

If your body is in need of more oxygen should you increase or decrease respiration (breathe faster or slower)?(1 point)
Responses

Decrease (breathe more slowly) and breathe more deeply
Decrease (breathe more slowly) and breathe more deeply

Increase (breathe faster) and breathe more shallowly

Answer 5

If your body is in need of more oxygen, you should **increase respiration** (breathe faster) to take in more oxygen. This response typically occurs during physical activity or situations where the body demands more oxygen.

So, the correct response is:

- **Increase (breathe faster) and breathe more shallowly.**

Answer 6

If your body temperature increases (you get hot), what happens to your rate of perspiration? Do you sweat more or less?(1 point)
Responses

Your rate of perspiration increases (you sweat more to cool off)
Your rate of perspiration increases (you sweat more to cool off)

Your rate of perspiration decreases (you sweat less to stay warm)
Your rate of perspiration decreases (you sweat less to stay warm)

No change occurs

Answer 7

If your body temperature increases and you get hot, your rate of perspiration **increases**, meaning you sweat more to help cool off the body through the process of evaporation.

So, the correct response is:

- **Your rate of perspiration increases (you sweat more to cool off).**

Answer 8

As your blood sugar drops, your body will release what chemical to stabilize it (bring it back to normal)?(1 point)
Responses

insulin
insulin

oxygen
oxygen

glucagon
glucagon

carbon dioxide

Answer 9

As your blood sugar drops, your body will release **glucagon** to help stabilize it and bring it back to normal levels. Glucagon signals the liver to release stored glucose into the bloodstream.

So, the correct response is:

- **glucagon.**

Answer 10

Read the section about Heart Rate, and answer the following.

How to adjust the heart and respiration rates if the body's oxygen level drops too low?

(2 points)
Responses

Decrease heart rate and increase respiration rate
Decrease heart rate and increase respiration rate

Increase heart rate and respiration rate
Increase heart rate and respiration rate

Increase heart rate and decrease respiration rate
Increase heart rate and decrease respiration rate

Decrease heart rate and respiration rate

Answer 11

If the body's oxygen level drops too low, the appropriate response would be to **increase both the heart rate and the respiration rate**. Increasing heart rate helps to pump blood more quickly, delivering more oxygen to the tissues, while increased respiration rate allows for greater oxygen intake into the lungs.

So, the correct response is:

- **Increase heart rate and respiration rate.**
