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).
As it is the region of the colon closest to the bodyâs exterior, the sigmoid colon is commonly used to screen for and prevent colon cancer. A sigmoidoscopy is a procedure wherein an endoscope is inserted through the anus and rectum and used to observe the mucosa of the sigmoid colon.
