Which organs are recognized as radioresistant?

Radioresistant organs are those that have a higher tolerance to radiation exposure and are less likely to suffer significant damage when exposed to radiation. Among the options presented, salivary glands and kidneys are the correct examples of radioresistant organs.

Salivary glands possess a moderate level of resistance to radiation due to their structure and function. While they can be affected by high doses of radiation, the damage is often less severe compared to organs that are more sensitive. The kidneys also exhibit radioresistance; they can recover partially after radiation therapy, although they remain vulnerable to high radiation levels.

In contrast, lymphoid tissues, bone marrow, intestines, skin, and reproductive cells are typically more radiosensitive, meaning they are more susceptible to the harmful effects of radiation. Understanding the differential sensitivity of these organs is crucial in treatment planning for patients undergoing radiation therapy, ensuring that those organs can sustain greater doses while minimizing damage and improving overall outcomes.
