As noted previously, the most sensitive organs are the blood forming organs and the gastrointestinal system. The biological effects on the whole body from exposure to radiation will depend upon several factors.
Which organ is most radiosensitive?
The digestive tract is among the most radiosensitive organs in the body and its function, which is partly regulated by gastrointestinal (GI) peptides, can be affected by radiation exposure.
What organs are affected by radiation?
In rare cases, radiation can cause more severe and permanent side effects such as damage to the lungs, heart, bowel, bladder or other organs. There is also a small risk that the radiation treatment may actually cause, years later, a new cancer.
Which human organ is most susceptible to radiation?
Which human organ is most susceptible to harmful radiations of The correct answer is Lungs. If you find any mistake in Which human organ is most susceptible to harmful radiations then definitely tell us through comment, or new Write the answer.
Which organ is least sensitive to radiation?
Amongst the body cells, the most sensitive are spermatogonia and erythroblasts, epidermal stem cells, gastrointestinal stem cells. The least sensitive are nerve cells and muscle fibers. Very sensitive cells are also oocytes and lymphocytes, although they are resting cells and do not meet the criteria described above.
What tissue is most resistant to radiation?
The differentiated fixed postmitotic cells are the most radioresistant. This class includes the long-lived neurons, skeletal muscle cells and erythrocytes.
Why some organs are more radiosensitive than the other organs?
Actively dividing cells that are less differentiated tend to show higher radiosensitivity. For example, hematopoietic stem cells in bone marrow are differentiated into various blood cells, while dividing actively.
What are radiosensitive organs?
Hematopoietic system: Bone marrow and lymphatic tissues. (spleen, thymus gland, lymph node) Reproductive system: Testis and ovary. Gastrointestinal system: Mucous membrane and small‐intestinal.
Which tissue is the most vulnerable to radiation damage?
The tissues most affected by radiation are those that undergo rapid replacement, such as bone marrow, the lining of the gastrointestinal tract, and skin. Slower-growing tissues, such as those of the brain and liver, require either high doses of radiation or prolonged exposure before they show symptoms of degeneration.
What cells are most radiosensitive?
The differentiated fixed postmitotic cells are the most radioresistant. This class includes the long-lived neurons, skeletal muscle cells and erythrocytes.
