The intriguing world of Homeostasis

And the digestive system

Learn more about Homeostasis

You may be wondering what homeostasis is and why is it so special? Homeostasis is the tendency of the body to seek and maintain a condition of balance or equilibrium within its internal environment, even when faced with external changes. A simple example of homeostasis is the body's ability to maintain an internal temperature around 98.6 degrees Fahrenheit, no matter what the temperature outside is. Another example is how animals keep their body in a stable condition by adjusting their ph, temperature, amounts of oxygen and carbon dioxide in their blood and so on.If your body does not maintain homeostasis there are many harsh effects. Dehydration, kidney failure and liver failure are all homeostasis disorders.

The digestive system

The digestive system is also very important. First of all the digestive function helps you digest your food and turn it into energy. It breaks your food down.This system is essential to your health because without it the body can not be nourished or rid itself of waste. It starts at the mouth, includes the esophagus,stomach,small intestine, large intestine and rectum, and end at the anus.There are also many problems that can come from the digestive system including nausea,vomiting and difficulty swallowing.

One week of eating junk food is enough to trigger memory impairment in rats.

Studies in animals have also shown that fats from junk food slow down the ability to learn new skills.


3. It can damage your liver.

A study reported that people who ate junk food and shunned exercise showed changes in liver enzymes within four weeks. These changes were similar to those observed in people with alcohol abuse. According to some studies, it’s the high level of trans fats found in a number of junk food which cause liver dysfunction due to deposition in the liver.
