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.
Experts recommend men and women begin testing for colon cancer at age 50. Blacks should begin screenings at age 45. For those with a prior or family history of colorectal cancer or polyps, screenings should begin earlier -- at age 40 or 10 years before the family member had the disease, whichever is sooner.
