Homeostatic Control

Living organisms have a limited range of environmental and physiological conditions in which they can operate. When these conditions change rapidly, organisms must adapt quickly to preserve their life. To maintain a delicate equilibrium for survival, living organisms have processes that allow them to counter potentially dangerous external or internal stimuli. This concept of always trying to return to a state of balance is called homeostasis . Homeostatic systems address a variety of stimuli and dangers within an organism.

The human body has numerous homeostatic regulation pathways, including:

• body temperature
• breathing and gas exchange,
• body water and electrolyte content
• blood pressure
• calcium levels
• feeding and digestion
• hormonal regulation
• blood sugar levels.

Homeostatic pathways typically have a basic workflow that includes sensors, a control center, effectors, and a feedback loop.

When the intensity of a stimulus exceeds a tolerance threshold value, the body activates homeostatic pathways to counteract it. For example, when the body gets too warm, it starts sweating and dilates blood vessels to dissipate body heat. The body reaches a stable state, different from the normal resting state, but stable enough not to cause irreversible damage. When the stimulus decreases or disappears, the homeostatic systems return the body to the initial balance. However, if the intensity or duration of the stimulus is too great, the homeostatic control may be unable to cope, leading the body to enter a state of shock or rapid self-degradation.

Homeostatic regulation pathways are not always independent from each other, and some may impact similar physiological variables. For instance, the homeostatic response to cold temperatures triggers muscles to shiver, consuming blood sugar by muscle tissues. Therefore, another homeostatic process has to act to maintain blood sugar levels.

Laboratories can be very dangerous, especially if you’ve never set foot in one before. So in this simulation, you’ll get the chance to make your debut in a virtual one! You will learn how to use the lab safety equipment and how to react in case of an emergency. Detect and eliminate sources of danger and pass on your lab safety knowledge to friends.

Identify hazards

Safety first! Always pay attention to potential hazards when you enter a lab. In this simulation, you will create a tidy and safe working environment by identifying and eliminating hazards in the lab. You will be introduced to the lab safety rules and the safety equipment, which will help you and your colleagues if something was to go wrong in a real lab.

Emergency training

You will be introduced to the basic hazard symbols used to categorize dangerous materials. You’ll use this knowledge to prevent dangerous situations such as acid spills. But you will also learn how to deal with unlabeled, potentially hazardous chemicals. By mastering such situations in this simulation, you won’t have to worry about being exposed to any real danger. You will learn how to operate the eye-wash and also get an introduction to various other pieces of lab safety equipment.

Spread your knowledge

It is important to share your newly acquired knowledge with your colleagues. In this simulation, you will meet your friend Lucy who’s never worked in a lab before. Pass on your lab safety knowledge and help her dress appropriately for a day in the lab.

Will you be able to apply your knowledge and make sure that you and your friend stay safe in the laboratory?

For Science Programs Providing a Learning Advantage

“They did the simulation at home, then completed the in-person lab within 30 minutes, no questions asked, and passed the quiz with flying colors.”

"I saw some of the students who clearly didn’t necessarily like sitting there reading a book discover they could turn on Labster and keep up with the rest of the class because it spoke to them.

"Having something that's engaging for the students gives teachers that opportunity to breathe and get excited again. Because they're seeing the kids light up, they're seeing the kids engage with content."

"The question always is, ‘Can we demonstrate that the students are meeting course outcomes?’ Check! We can do that.”

"We surveyed over 400 students. More than 90% thought Labster was easy to navigate, and that it was fun, but more importantly, most of them felt confident that they could execute the labs in person. And that confidence is a big deal."

“The Labster simulations get students to do things, and they're not just sitting there consuming a webinar where their mind can drift. They become an active participant in that learning experience.”
