In a virtual activity where you can control various body systems of a virtual person, the following systems can typically be controlled:
- Blood Delivery - This involves the circulation of blood throughout the body.
- Oxygen Need - Monitoring and adjusting oxygen levels in the body.
- Food Intake - Controlling the consumption of food and its impact on the body.
- Pulse - Monitoring and adjusting the heart rate.
- Glucose - Managing blood sugar levels.
- Body Temperature - Controlling the body's temperature regulation.
- Sleep - Regulating sleep patterns.
- Blood Pressure - Monitoring and controlling blood pressure levels.
Depending on the specifics of the virtual activity, you may have the ability to control all these systems. In a general sense, for a virtual simulation focusing on physiology or body systems, options like Blood Delivery, Oxygen Need, Pulse, Blood Pressure, and possibly Glucose would often be included.
If you need to select a limited number, please clarify any additional constraints or specifics about the activity.
