Final answer:
Aseptic techniques involve protocols to maintain a sterile environment, crucial for preventing contamination and the spread of disease. Hand washing is a key part of avoiding pathogens.
Step-by-step explanation:
The practices that remove or destroy pathogens and prevent them from spreading from one person or place to another are called aseptic techniques.
Aseptic technique involves a combination of protocols, including the use of sterilized materials and strict procedures to maintain a sterile environment, in order to prevent contamination and the spread of infectious agents.
This is crucial in medical settings but also applies to laboratories and other places where maintaining sterility is important. Washing hands frequently is also an important part of avoiding pathogens and preventing the spread of diseases.
