Pelvic ultrasound is a procedure in which high-frequency sound waves create images of the pelvic organs. The sound waves are projected into the pelvis, and measure how they reflectâor echoâback from the different tissues.
Latin was the language of ancient Rome, however the educated classes also were fluent in Greek as Greek was the international language of the ancient world. For example, if a diplomat had trouble with a certain language, he could always converse in Greek and be understood.
Since Latin was very important to Christianity through many centuries, it is still spoken today during some religious activities such as prayers and cults. For the same reason, it is considered official in Vatican, where the Pope, the leader of the Roman Catholic Church, lives. People in the Vatican sometimes communicate in Latin (if they have different mother tongues) and sometimes in ceremonies.
