Final answer:
HL7 enables communication between different healthcare systems and applications, facilitating the exchange of healthcare data.
Step-by-step explanation:
HL7, which stands for Health Level 7, is a set of international standards that allows communication between different healthcare systems and applications. It enables the exchange of electronic health records, medical images, lab results, and other healthcare data.
HL7 allows two main things to communicate: systems and applications. For example, an electronic medical records system can communicate with a hospital information system, a laboratory system can communicate with a radiology system, or a pharmacy system can communicate with a patient management system.
HL7 facilitates interoperability and the seamless exchange of information in the healthcare industry.
