Fun Facts about Homeostasis and the Digestive System
Many bodily steady states follow this pattern. Blood glucose level, blood pH, and osmotic pressure are examples. The key concepts are: an observable steady state that persists over time with minor changes; thresholds above and below this normal range; a sensory input that reports changes in the steady state; and effector mechanisms for restoring the steady state.
System interactions
digestive system
Digestion is the breakdown of food into small molocules.The digestive system is divided into two major parts: The digestive tract (alimentary canal) is a continuous tube with two openings: the mouth and the anus.
The digestive system interacts with the skeletal system and musular system as i wrote to the right.
Skeletal system
The organs in the skeletal system are: cartilage, tendons,ligaments, joints
The adult human skeletal system consists of 206 bones, as well as a network of tendons, ligaments and cartilage that connects them. The skeletal system performs vital functions — support, movement, protection, blood cell production, calcium storage and endocrine regulation — that enable us to survive. Human infants are born with about 270 bones, and some of the fuse together as the body develops.
As we discussed in the muscular system.
Muscular system
There are 3 types of muscles : Cardiac muscle, Smooth muscle, and skeletal muscle.
The muscular system is responsible for the movement of the body. There are about 700 named muscles that make up half of a persons weight. Each muscle is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves.
Several features of the digestive tract help to demonstrate the role of the muscular system in working with the digestive system. At the mouth, the muscles of the jaws and tongue break food into pieces. Muscles of the throat move food down the esophagus. In the stomach, churning motions produced by muscles break food into smaller bits and mix it with stomach acid. Finally, muscular contractions of the intestine move food through the remainder of the digestive tract.
Your bones and muscles work together through a series of impulses and signals communicated between the brain and skeletal muscles. In order to move, the nervous system then sends signals a skeletal muscle to contract. When the muscle contracts, this movement causes the attached bone to follow.
The Foods We Eat
A negative effect of junk food on children is rapid weight gain, often leading to excessive weight and sometimes obesity. This is because it often tastes good, is not very filling and is high calorie. Candy, soft drinks, French fries and other fried foods, pizza, burgers, baked goods and ice cream are examples of high-sugar or high-fat foods which provide hundreds of calories per day for the typical American youth ages 2 to 18, type two diabetes, Nutritional Deficiencies, Cardiovascular Disease,
Obesity: Junk food enthusiasts are prone to put on weight, especially when they eat this kind of food very often. The fat and processed flour only make people fatter and unhealthier, as does the oil and grease that are used for fries, chips, donuts and other deep-fried foods. Statistics even show people who eat junk food tend to accompany it with sodas and alcohol, which are either laden with sugar or empty calories and both increase a person’s tendency to put on weight.
