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.
âIf you have a first-degree relative with colon cancer, exams should start between ages 35 and 40,â says Fuchs. Colonoscopy is the most reliable test, because doctors can visually study the entire colon and rectum, Fuchs says.
