why can adults continue to function relatively normally after surgery to remove the thymus or spleen?
Adults can continue to function relatively normally after surgery to remove the thymus or spleen because these organs have secondary or redundant functions, and other parts of our body can compensate for their absence.
The thymus is a part of the immune system located in the chest, behind the breastbone. It plays a vital role in the development and maturation of white blood cells called T lymphocytes, which are essential for the immune system. However, the thymus tends to shrink and become less active as we age, and by adulthood, it is less crucial for immune function. Even if the thymus is completely removed in surgery, most adults have a sufficient number of mature T lymphocytes already in circulation to maintain immune responses.
The spleen, located in the upper left abdomen, is involved in filtering the blood, removing old or damaged red blood cells, and helping to fight certain types of infections. However, the spleen is not the only organ responsible for these functions. Other organs, such as the liver and bone marrow, can compensate for the absence of the spleen. Additionally, our immune system has other defense mechanisms, including white blood cells and antibodies, which continue to provide adequate protection even without the spleen.
It is important to note that while adults can function relatively normally without these organs, their absence might increase the risk of certain infections or immune-related disorders. It's crucial to follow the advice of medical professionals and take necessary precautions to mitigate any potential complications.
