Food Allergies an American Obsession? |
| September, 2006 (BUSINESS WIRE) -- Food allergies are increasingly top-of-mind for many Americans. In fact, one out of every three people in this country claim to have a food allergy of one kind or another. But the science doesn't support these fears. Government and medical association estimates put the actual incident rate at only between one in 25 and one in 70. And a new survey finds parents don't seek medical help. |

How the Body Works : The Regions of the Brain |
| The Regions of the Brain The brain has three major functional and anatomical parts--the forebrain, midbrain and hindbrain. The forebrain consists of the cerebral hemispheres, thalami, hypothalamus and limbic system. The top inch of the brain stem is the midbrain. The hindbrain includes the cerebellum, the pons and the medulla. Other parts of the brain's anatomy include: the cerebral cortex, a thin layer of nerve cells on the surface of the cerebral hemispheres; the cerebrum, composed of many millions of nerve fibers, is covered by the cerebral cortex; the corpus callosum, a C-shaped collection of fibers, forms a bridge between the left and right hemispheres; the thalamus, which relays and receives messages to and from other areas of the brain; the limbic system, concerned with memory and emotion; the cerebellum, the largest part of the hindbrain and responsible for balance and the fine control of muscle movements; and the hypothalamus, which lies below the third ventricle of the brain, and regulates many of the body's functions and the activity of the pituitary gland. |

Digestive System |
| The main function of the digestive system it to break up food and to take it in as energy. It first starts at the mouth where the teeth mechanically digest the food by breaking it down into smaller pieces and the saliva in the mouth containing enzymes break down the food chemically. When you swallow the food, your mouth forces the food from your mouth into your esophagus, which is a muscular tube that moves it down your stomach. Peristalsis is a series of muscles that contract along the walls to push it down. Three is a flat called the epiglottis that closes the tube down to the lungs so the food doesn't go down the wrong way. After the esophagus it goes into the stomach where it churns and breaks down the food mechanically and the stomach acid and enzymes break down the food chemically. After the food is in the stomach for about two to four hours it is pushed down into the small intestine where there are small hairs like thins called villa that absorb nutrition. They are also two structures that help break down the food. One of them is the pancreas that is a soft gland that helps break down the carbohydrates, proteins, and fats with enzymes. The second one in the liver, which creates biles, which is a chemical that helps break down fats, the biles are stored inside the gallbladder. After the small intestine there is the large intestine that absorbs water and makes protein, after the large intestine it goes into the rectum and out of the body. |
