The aorta (/eÉªËÉËrtÉ/) is the main artery in the human body, originating from the left ventricle of the heart and extending down to the abdomen, where it splits into two smaller arteries (the common iliac arteries). The aorta distributes oxygenated blood to all parts of the body through the systemic circulation.
Men and women should have a colonoscopy at age 50. African American men and women should have their first screening at age 45. Individuals with a history of a first-degree relative (parent, sibling or child) or a personal history of colorectal cancer should be screened using a different schedule.
You should have a colonoscopy every 10 years starting at age 50. Alternatively, you may get a flexible sigmoidoscopy every five years, a double-contrast barium enema every five years or a CT colonography (virtual colonoscopy) every five years. However, a colonoscopy will be needed if any of those results are positive.
