What is the main purpose of a biopsy procedure?

  1. long and slender with a very small internal diameter

  2. that part of the central nervous system that includes all the higher nervous centers

  3. taking out and examining living tissue from a living thing

  4. unit of heat required to raise the temperature of water

The correct answer is: taking out and examining living tissue from a living thing

The primary goal of a biopsy is to remove a small sample of living tissue for examination, often to diagnose disease or determine the nature of a lesion. This process provides valuable information about the type of cells present and whether any abnormalities exist, such as cancerous cells. It is a critical procedure in medical diagnostics, allowing healthcare professionals to make informed decisions about treatment based on the characteristics of the tissue analyzed. The other options do not relate to the purpose of a biopsy, as they describe unrelated concepts, such as physical characteristics, parts of the nervous system, or units of heat measurement.
