Brown Beijing News weekly of the new knowledge

On the excretion of jokes, thousands of years long occupies a variety of top front row location joke.

United States comedy "life in the big bang" in this story. Early in May this year to play a set in the design, engineer Wolowitz zero gravity of space toilet has failed, the play four science and drifting on the ground maintenance, results started modeling connected backwards vacuum piping, a simulation of going to the burgers "launch" to the ceiling.

Smell: the coexistence of odor and sniffed its rare fragrance

In this respect is actually a very serious and very scientific topic.

The scent of took going — — although we see here maybe will frown, in fact, going to the odor constituents is not the only, which is quite complex of ingredients. The majority of them are intestinal bacteria by-products of their hard work. For example, hydrogen sulfide, pure product is the smell of rotten eggs; thiol, is a series of compounds collectively, gas in something they worshipped their giveth, and indole, Escherichia coli and its friends decomposition product of tryptophan.

When I was still in school, sixth floor, the brother of a lab will be a little careless in high concentration of indole solution into the sewers, then experiment building was spectacular and interesting scenes: fifth floor was quickly emptied after a few minutes on the first floor also stir.

How do you describe the indole smell? textbooks written by is a "strong fecal odour". However, babes Dresser those prices expensive perfume, almost without exception that contains this kind of thing, because textbooks also wrote "indole after diluted by a large number can have a pleasant odor." Perfume industry pipe is called the "cat" Xiang ", as the long tail, aftertaste.

In the light of those smelly things are generally more sulfur-containing substances, and their sources are primarily food proteins.

So in General, the meat is going to stink to death while eating ' going to smell the fresh.

Color: Brown from blood

Most of the time, going to the toilet is brown.

This fact has long plagued young I — for what I am large white bread to eat every day, but La Brown going? the answer to the question involves a lot of complex physiological processes. Going to the Brown, comes from our bright red blood. Every day, our blood will generate a large number of red blood cells, which contain hemoglobin is decomposed into heme and bilirubin. Bilirubin is transferred to the liver, bile, and then enter the dye it Brown. Subsequently, bile is discharged into the duodenum in the process of digestion of fat, while all the way along the line the intestine of bilirubin, and digestion of food fully mixed, give them the Tan.

If you are going to always pale yellow and might be Gilbert syndrome (Gilbert'ssyndrome) results.

This genetic issues is very common, approximately 5%-10% of people have this problem. They deal with the death of a little slower, so blood bilirubin levels slightly higher, and bile bilirubin is low. The vast majority of GS patients life will not be aware of its existence. If the light yellow also accompanied by diarrhea, Giardia lamblia disease (giardiasis) symptoms. It is estimated that at present the world infected with giardia lamblia nearly 3 billion people. Fortunately, the disease would only lower for immunity extremely seriously harm a person.

Green is in many ways possible, first, eat too much green plants; second, iron, iron absorption, to be green ferrous salt forms just discharged; third, the pH of the inte

stines reaches the value of a subtle, bilirubin becomes biliverdin, still a baby at the breast appears frequently. White going to the very rare. One of my friends who claimed to be in a time of eating ice cream 33 McDonald had rapidly after 甜筒 "production" of white going to the toilet. In addition to this extreme case, white will most likely do x-rays of digestive drink "barium" results.

Health professionals are most interested in is "red"; in other words, it is often a symptom of gastrointestinal bleeding, blood red, the more vivid description, generally the more fresh also means bleeding point away from the "end" the closer.

If you have a dark black and even tar color, it may be the result of upper gastrointestinal bleeding. Yet another Red is no need to fuss about it, when I was a child, I often pull the Red will — in a few days, going to the places that grow a green watermelon seedling.
