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.
Now federal guidelines suggest that most people can stop getting colonoscopies after age 75. In general, the risk of cancer among young adults is so low that screening healthy young people (who donât have unusual risk factors) doesnât make sense.ow federal guidelines suggest that most people can stop getting colonoscopies after age 75.
