specimens

A specimen is a sample of a living or non-living thing used for study or analysis. In medicine, it often refers to blood, tissue, or other biological material taken from a person to help diagnose or monitor health conditions. In science, specimens can be samples of plants, animals, minerals, or other substances collected for research or display. They are carefully gathered, preserved, and examined to gain insights about their nature, origin, or health. Essentially, specimens are the tangible pieces scientists and doctors examine to better understand the world around us or to diagnose and treat illnesses.
