Homeostasis comes from the Greek words for “same” and “steady.” It was first used by Dr. Walter Cannon in his 1030 book, The Wisdom of the Body. This scientific term refers to the different ways that your body—or that of any other living being—maintains and regulates the stable conditions needed for survival and optimal health. Certain internal con...
Homeostasis relies on biological feedback from your body. This feedback is known as a negative feedback loop, but that’s actually a good thing! 1. A negative feedback loopmeans that your body is working to reduce fluctuation and maintain its inner stability. 2. A positive feedback loopmeans that the variables in your homeostatic systems are moving ...
Your body’s different systems are responsible for maintaining its optimal steady state. They “listen” on a cellular level for signs of distress. When one of the key variables falls out of the acceptable range, your nervous system detects this deviation and sends a signal to your brain. Your brain then sends your muscles, organs, and/or glands to wo...
Your body works in big and small ways all day to maintain homeostasis. Something as simple as going for a walk (raising your body temperature) or drinking a glass of juice (raising your glucose level) can trigger a negative feedback loop and evoke a biological response. Let’s look at some of the most common ways in which your body maintains homeost...
Homeostasis generally occurs without you even realizing it. While you might notice some of the warning signs of hypoglycemia (shaking, weakness, confusion, blurred vision), you certainly won’t notice your body converting glycogen to boost your glucose level. But although homeostatic reactions are automatic, you’re responsible for keeping your body ...

- Appendix. This organ is about the size of your little finger and hangs from the lower right side of your colon. For reasons that aren't clear, this part of the intestinal tract sometimes becomes blocked, infected, or inflamed.
- Tonsils. A network of lymph nodes throughout the body is part of the immune surveillance system that helps trap dangerous invaders such as bacteria and viruses.
- Adenoids. Situated in the back of the nose where the nasal passages meet the mouth and throat, adenoids are similar to tonsils. They can also become inflamed, infected, and swollen.
- Gallbladder. The gallbladder sits just under the liver in the upper right part of the abdomen. It stores bile made in the liver and releases it into the digestive tract when needed to help digest fatty foods.

Anything that gets past the cilia is trapped in the mucus that lines the trachea and the bronchial tubes that take air from the trachea into the lungs. The human body is well-equipped to trap these particles, but the body works best when air is relatively pure before it is inhaled. That is why many people use (air purifiers) at work and home.
