And The Digestive System....How the Human Body Works
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:
- Mixing and Movement
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.

Systems That Interact With The Digestive System
The Three Systems
The muscular system consists of more than 700 different muscles! It is responsible for the movement in the body. Both the Digestive System and Muscular System maintain Homeostasis.The purpose of the muscular system is to cause movement. Muscles are important in chewing food, swallowing, and the mixing and the digestion products through the Gastrointestinal tract. Muscles help the jaw move when you chew. They also help you swallow your food as well.
The skeletal system consists of of bones, cartilage, tendons, ligaments, joints, and other connective tissue that supports and binds tissues and organs together. It's primary function is to form a solid framework the supports and protects the body's organs and anchors the skeletal muscles.The digestive system interacts with the skeletal system by the phosphorous, which helps bones and teeth, too. The skeletal system holds the digestive system which is the frame of your whole body. Since the digestion of the body starts in the mouth, the teeth are really important, and the teeth are part of the skeletal system. Bones are really important in mastication, or chewing.
The cardiovascular system consists of the heart, blood vessels, blood, lymph, lymphatic vessels, and glands. It's main function is for the blood to circulate through a network of vessels throughout the body to provide individual cells with oxygen and nutrients and helps dispose of metabolic wastes. Without the cardiovascular system, also known as the circulatory system, the nutrients in the digestive system would not exist! The organs in the digestive system need the cardiovascular system to continue to digest food. It needs the blood that the cardiovascular distributes for its nutrients, as well as to have the nutrients spread, so that the body functions evenly.
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.
