Homeostasis

and the digestive system

What is homeostasis?

Homeostasis is your body's way of keeping balance. Your body does this in many ways, and in all of your organ systems. homeostasis can help you in many ways, when your doctor takes your temperature he/she does that to see if your body has a virus which can knock the balance inside your body off track. Failing to maintain homeostasis will result in DEATh.Homeostasis or homoeostasis (homeo- + -stasis) is the property of a system in which variables are regulated so that internal conditions remain stable and relatively constant. Examples of homeostasis include the regulation of temperature and the balance between acidity and alkalinity (pH).

digestive system and junkfood

Digestive system


The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract). The alimentary canal is made up of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines. In addition to the alimentary canal, there are several important accessory organs that help your body to digest food.


Junkfood


"Junk food" generally refers to foods that contribute lots of calories but little nutritional value. Of course, what's considered "junk food" depends on whom you ask. Some might say pizza is junk food, for example. But I personally don't think so, since it contributes real food with nutrients, like cheese and tomato sauce. Add whole-wheat or part whole-wheat crust, plus veggies as a topping, and I'd say pizza completely exits the junk food category.
