A diener is someone who helps prepare and handle dead bodies. They work in places like hospitals and medical schools. When someone dies, their body is usually taken to a special room called a morgue. This is where dieners work.
The diener's job is to make sure the body is cleaned, disinfected, and placed in the right position before it is examined by a doctor or used for research. They may need to remove organs and tissues for testing, so they have to be very careful and skilled. They wear special protective clothing to keep themselves and others safe from germs and harmful chemicals.
Once the body has been prepared, it may be used for medical research or returned to the family for a funeral. Diener's work is very important because it helps doctors and scientists learn about diseases and how to treat them. It also helps families say goodbye to their loved ones in a respectful and dignified way.
