You've completely forgotten about that pizza lunch you just ate. But it's still in your stomach — sort of like a science experiment that happens all the time! And the digestive system will be busy at work on your chewed-up lunch for the next few hours — or sometimes days, depending upon what you've eaten.

This process, called digestion , allows your body to get the nutrients and energy it needs from the food you eat. So let's find out what's happening to that pizza, orange, and milk. Even before you eat, when you smell a tasty food, see it, or think about it, digestion begins. When you do eat, the saliva breaks down the chemicals in the food a bit, which helps make the food mushy and easy to swallow.

Your tongue helps out, pushing the food around while you chew with your teeth. When you're ready to swallow, the tongue pushes a tiny bit of mushed-up food called a bolus say: BO-luss toward the back of your throat and into the opening of your esophagus, the second part of the digestive tract.

It moves food from the back of your throat to your stomach. But also at the back of your throat is your windpipe, which allows air to come in and out of your body. When you swallow a small ball of mushed-up food or liquids, a special flap called the epiglottis say: If you've ever drunk something too fast, started to cough, and heard someone say that your drink "went down the wrong way," the person meant that it went down your windpipe by mistake.

This happens when the epiglottis doesn't have enough time to flop down, and you cough involuntarily without thinking about it to clear your windpipe. Once food has entered the esophagus, it doesn't just drop right into your stomach. Instead, muscles in the walls of the esophagus move in a wavy way to slowly squeeze the food through the esophagus.

This takes about 2 or 3 seconds. Your stomach, which is attached to the end of the esophagus, is a stretchy sack shaped like the letter J. It has three important jobs:. The stomach is like a mixer, churning and mashing together all the small balls of food that came down the esophagus into smaller and smaller pieces. It does this with help from the strong muscles in the walls of the stomach and gastric say: GAS-trik juices that also come from the stomach's walls. In addition to breaking down food, gastric juices also help kill bacteria that might be in the eaten food.

This affects the regulation of body temperature, blood pressure, stress response, normal swallowing and digestion. An estimated 1 in 30 Ashkenazi Jews is a carrier of FD. Bloom Syndrome Characterized by short stature, sun-sensitive facial skin lesions, an increased susceptibility to infections and a higher incidence of leukemia and certain cancers.

The carrier rate is about 1 in in the Ashkenazi Jewish population. Fanconi anemia — Type C A disease associated with short stature, bone marrow failure and a predisposition to leukemia and other cancers. Some children may have learning difficulties or mental retardation. Approximately 1 in 89 Ashkenazi Jews is a carrier for this condition.

Mucolipidosis IV Caused by the accumulation of certain harmful substances throughout the body. Individuals with ML IV experience a range of levels of motor and mental retardation, with developmental delays often manifesting themselves as early as the first year of life. Other symptoms can be related to the eyes, such as corneal clouding, pseudostrabismus and retinal degeneration. Cystic Fibrosis A multi-system disorder that causes the body to produce a thick mucus. The mucus accumulates primarily in the lungs and the digestive tract, resulting in chronic lung infections and poor growth.

CF does not affect intelligence. The carrier rate for CF among all Caucasian individuals is approximately 1 in If an individual is found to be a carrier, genetic counseling is available at many clinics throughout the country to discuss the implications of this finding. If partners are found to be carriers of the same disorder s , a genetic counselor can provide information and support, which may be helpful in making important family planning decisions.

The results of these tests are highly accurate. However, there is a slight possibility that someone who tests negative for being a carrier could still be a carrier. There may be rare mutations that DNA testing may not pick up. Victor Center for Jewish Genetic Diseases.
