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).
A sigmoidoscopy is a screening or diagnostic test that allows a doctor to see inside the lower 20 inches of the sigmoid colon and rectum (also called the large intestine), which plays an important role in the bodyâs ability to process waste.he doctor views the inside of the colon through the scope or on a video monitor. A sigmoidoscopy is often used to find intestinal polyps, which are small abnormal growths that may become cancerous, as well as to screen for colorectal cancer.
