What did YOU do this weekend?
Things I learned this weekend:
The digestive system, which simply put, breaks down food into a form our body can use, is 28 feet long and consists of the mouth, esophagus, stomach, small intestines, large intestines and anus. Digestion starts in the mouth where food is chewed and broken into smaller pieces. The mouth's saliva contains enzymes that turn starches into sugars. The food then travels down the ten inch tube, with a one inch diameter (about the size of a quarter) called the esophagus. The esophagus connects the mouth to the stomach. The stomach is a strong bag-like organ that squeezes the food for about 2 hours before it's passed to the small intestines. The small intestines are narrow - also about 1" in diameter, and 22 feet long. It is here where the liver and pancreas help aid in digestion. The liver produces bile that breaks down fat and the pancreas creates a chemical that breaks down stomach acid, without which the acid would burn through the walls of the small intestines. Ouch. Anyway, the nutrients are extracted from the food-like paste and travel through the wall of the small intestines out into the blood. This takes about 3-6 hours. The only thing left is waste which is pushed into the large intestines. The large intestines are about 3" in diameter and 4' long. Water is extracted from the waste and every 10 to 24 hours the waste exits our body via the anus.
Things my 9 year old daughter learned this weekend:
Her mother is the meanest mother in the entire world because her mother made her study for a stupid digestive system test which meant she had to miss Drake & Josh which isn't even on TV that much anymore and if her mother really knew her then her mother would know that Drake & Josh is very important to her, but obviously her mother doesn't care about her at all and is just plain mean. Also, anus is a very funny word and you can laugh at it every time it is mentioned.
