One thing to be mindful of is that while all browsers support the IFRAME element, there is still limited support for some of the HTML5 features. 1  Using overflow to turn off scrolling is not reliable. If you don't want scrollbars on your iframes, you should continue to use the scrolling attribute.
Sigmoid colon, a terminal section of the large intestine that connects the descending colon to the rectum; its function is to store fecal wastes until they are ready to leave the body. The sigmoid colon derives its name from the fact that it is curved in the form of an S (Greek sigma: Ï). Its size depends upon the amount of waste material in it, but when contracted its diameter is only about one inch (2.5 centimetres).
After food travels through the sigmoid colon, it enters the rectum. The rectum is a straight, muscular tube. The muscle layers are very thick to push food into the anal canal. The anal canal is the last 2-3 centimeters of the digestive tract.he liver is a very important part of the digestive system, even though food does not directly pass through it. The liver produces bile (a greenish fluid which aids in the digestion of fats), which is stored in the gall bladder.
