Homeostatis
And The Digestive System....How the Human Body Works
What is Homeostatis?
What Is The Digestive System?
The digestive system is a group of organs working together to convert energy and basic nutrients to feed the entire body. It is consisted of the stomach, teeth, tongue, salivary glands, liver, gallbladder, and pancreas. Six major functions take place in the digestive system:
- Ingestion
- Secretion
- Mixing and Movement
- Digestion
- Absorption
- Excretion
In the digestive system, the liver, which monitors the blood, is very important organ in Homeostasis. The liver breaks down toxic substances like alcohol and other drugs, and it produces urea, the end product of nitrogenous metabolism. The liver produces the plasma proteins and stores glucose as glycogen after eating. In between eating it releases glucose, thereby keeping the blood glucose concentration constant. The liver destroys old blood cells and breaks down hemoglobin--hemoglobin breakdown products are excreted in bile.

Junk Food VS Health
How The Foods We Eat Effect Homeostatis And Our Health
Fast food nutrition should make up a minimal part of a healthy diet. Fast foods and junk foods are high in fat, sodium and sugar, which can lead to obesity and a range of attendant health problems, including diabetes, heart disease, and arthritis. Junk food doesn't contain the nutrients your body needs to stay healthy. As a result, you any feel chronically fatigued and lack energy you need to complete daily tasks. The high levels of sugar in junk food puts your metabolism under stress; when you eat refined sugar, your pancreas secretes high amount of insulin to prevent a dangerous spike in blood sugar levels. Because fast food and junk food don't contain adequate amounts of protein and good carbohydrates, your blood sugar levels will drop suddenly after eating, leaving you feeling grumpy, fatigued, and craving sugar.
