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.

Answer
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
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)

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
Answered by GPT-4o mini
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.
Answered by GPT-4o mini
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.**
Answered by GPT-4o mini
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).**
Answered by GPT-4o mini
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.**
Answered by GPT-4o mini
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.**
