Why do we have body parts that can be safely removed? If they’re not needed, why do humans have them in the first place?
One theory is that these nonessential organs and glands once served important roles in the lives of our evolutionary ancestors but now represent anatomic remnants. For example, it was long thought that the appendix helped our predecessors digest food, but over thousands of years became obsolete. And some organs are supremely useful during certain stages of life, but then become expendable.This organ is about the size of your little finger and hangs from the lower right side of your colon.
. While it may settle down with antibiotic treatment, emergency surgical removal is often necessary.A network of lymph nodes throughout the body is part of the immune surveillance system that helps trap dangerous invaders such as bacteria and viruses. Consider your two tonsils as larger, specialized lymph nodes watching out for these intruders. They are located at the back of the throat just to the sides of and behind the uvula, the dangling piece of tissue above them.
Now, removing the tonsils is only recommended for people with repeated bouts of bacterial throat infections such as strep throat, a condition common in children. Once removed, other lymphoid tissue, including the actual lymph nodes, can take over the job of the tonsils.are similar to tonsils. They can also become inflamed, infected, and swollen. So when the tonsils are removed, the adenoids are generally removed at the same time. The combined procedure is called tonsillectomy and adenoidectomy.
