Homeostasis
How the food you eat affects your health.
Defining Homeostasis
Respiratory System
The respiratory system participates in a variety of homeostatic processes, and the two most important of these are maintaining pH and regulating gas exchange. Both of these homeostatic functions are related to the biochemical roles played by the two primary respiratory gases, carbon dioxide and oxygen. Oxygen enters the body as a component of the air we breathe and is processed by the lungs. Carbon dioxide, which is produced as a byproduct of cellular metabolism, travels through the bloodstream to the lungs and is exhaled.The activity of the human body is a manifestation of the combined labors of trillions of microscopic cells. The body needs food to eat and air to breathe, and the requirements of individual cells are similar. The fundamental reaction that enables cellular life transforms glucose and oxygen into carbon dioxide, water and energy. This is why the supply of oxygen in the bloodstream is a critical aspect of homeostasis -- with insufficient oxygen, cells cannot make energy. Carbon dioxide must also be carefully managed so that this waste product does not accumulate to problematic levels. By inhaling and exhaling, the respiratory system is able to take in oxygen and release carbon dioxide, and thus it plays a dominant role in homeostatic gas exchange.
Digestive System
The digestive system and homeostasis of the human body are inextricably related because humans are ingestive heterotrophs, meaning that the body is required to have a mechanism by which to assimilate an outside source of nourishment. In order for the digestive system and homeostasis regulation to be successful, the essential nutrients of the foodstuffs eaten need to be refined and manipulated, and the “wear and tear” of the structure of the digestive system needs to be repaired and replenished when needed. In addition, every body system depends on the breakdown and assimilation of nutrients to repair, build, and maintain tissues. An abundance of chemical, mechanical, and enzymatic processes are responsible for digestive system homeostasis.

The Truth Behind Fatty Foods
Yes Mcdonalds is bomb, but did you know that it's very deadly.The manufacturing process is very disgusting and requires hydrogen gas, high heat, lots of pressure and a metal catalyst.
Fast Food were never available to humans until about a hundred years ago and it amazes me that anyone thought this stuff would be fit for human consumption.
Our cells don’t know what to do with them and they can cause various harmful effects in the body.
Trans fats raise small, dense LDL cholesterol, lower HDL, increase fat in the abdominal cavity, lead to inflammation and insulin resistance.
In Mcdonalds Chicken Nugget there is very little chicken in the nuggets.Samples from two fast food chains contained mostly fat, connective tissue, and bones,bones?!? yes bones.
Did you know that hamburgers with grilled mark are not from the grill, they are fake grilled marks, they are spray painted on.
