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.
The age at which you should have your first colonoscopy varies according to your level of risk for developing colon cancer. Guidelines developed collaboratively by the American Cancer Society, the American College of Radiology and the U .S.f a family member was younger than age 50 when diagnosed with colon cancer, you should have the colonoscopy 10 years earlier than the age of that person when diagnosed.
