Why does the body attack a transplanted organ?

Biology
2 answers:
Leni [432]4 years ago
4 0

Answer:

A body attacks a transplanted organ because it does not recognize it as being made of self cells. It knows this because the new organ has antigens, a form of proteins that coat the organ. When a body's immune system recognizes these antigens and they are not similar enough to the body's own antigen's, it attacks to try and keep itself safe and healthy.

Answer:

A transplanted organ is viewed by our bodies immune system as a foreign object, much like when we get sick. Our body is just trying to protect itself. For this reason people that have a transplant have to take immunosuppression medication for the rest of their lives.

Cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called _____.
Montano1993 [528]

Cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called prokaryotes.

<h3>What are prokaryotic cells?</h3>

Prokaryotes are organisms whose cell (or cells) are characterized by the absence of a nucleus or any other membrane-bound organelles.

Prokaryotic cells are opposed to their eukaryotic counterparts that possess a membrane-bound nucleus that houses their genetic material (DNA).

Examples of prokaryotes are as follows:

  • Bacteria
  • Archeaebacteria

Therefore, cells, like bacteria and archaea, that do not have a nucleus in their cells have traditionally been called prokaryotes.
