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.igh Risk. The recommended age for a colonoscopy for people in this category is sometimes as young as 20 to 25 years. People at high risk for colon cancer are normally under the care of a specialist who makes the recommendation for a colonoscopy on the basis of careful monitoring and observation.
