Physiological _'s treatment of dissection of colon
Colon includes the caecum, promotes colon, the transverse colon, descending colon and second form colon, it is about 130cm long, it is about 1/4 of the small intestine. Colon is shorter and thicker than the small intestine, the diameter 7.5cm of caecum, diminishes gradually distally, second form colon terminal diameter has 2.5cm only.
The main function of colon absorbs the moisture and electrolyte, form, store and excrete the excrement and urine.
The absorption of water and sodium, mainly at half a colon in right, and descending colon and the second form colon absorb some moisture, but mainly in order to store and excrete the excrement and urine. So defecate in time, excrement and urine residence time, too long, moisture in the excrement and urine will absorb in colon, the excrement and urine becomes hard to become dry, it is difficult to cause and defecate.
In addition, colon has function of secreting potassium ion, therefore the density of potassium ion in the excrement and urine is higher than density of potassium ion of content thing of the small intestine.
The length of people's colon is about 100 centimeters (promote colon 15cm, transverse colon 50cm, descending colon 20cm, second form colon 45cm, so total length about 130cm of colon) ,Colon can change 2000c.c pieces of the intersection of sex and the intersection of chyme and the intersection of group and piece into the semi-solid excrement and urine of 200c.c, the moisture content has ninety percent to absorb by the colon.
Colon is the large intestine that people often say, are divided into three parts, Part one For rise colon, go back blind the intersection of department and the intersection of beginning and body upgo in right lower abdomen, this Section claims that colon rises; Walk to the intersection of liver and the intersection of song and the intersection of hand and parallel the intersection of body and left conduct call that transverse colon, then body fall, call descending colon as to left the intersection of spleen and song. Its underpart connects second form colon, rectum, rectum.
Colon includes the caecum, promotes colon, the transverse colon, descending colon and second form colon, it is about 130cm long, it is about 1/4 of the small intestine. Colon is shorter and thicker than the small intestine, the diameter 7.5cm of caecum, diminishes gradually distally, second form colon terminal diameter has 2.5cm only. The dissection characteristic of colon is three: Colon is taken: 3 narrow columns formed to the vertical muscle fibre of enteric wall are taken. Colon bring in caecum, rise colon and transverse colon clear colon obvious gradually from descending colon to second form comparatively. Colon bag: Because it is shorter by 1/6 than colon that is adhered to to take colon, the colon wall has been shortened into a lot of bag bags, call the colon bag. The lipoprotein of intestines hangs down: Organized by fat under the mucous membrane of enteric wall and gathered it. On the colon wall, especially there is most intestines lipoprotein that hang down near the colon strip, more and having base of a fruit at second form colon. Wrapped up by peritoneum outside what the enteric lipoprotein hangs down, there is too much fatty quantity sometimes, can turn back, even fall into the intestines, cause intussusception.
