Answer :
Final answer:
The ceremony at the top of Aztec pyramids involved human sacrifices with heart extraction and occasionally involved the losing team's captain as a human sacrifice in ball games.
Explanation:
Human sacrifices involving the extraction of victims' hearts were a prominent ceremony that took place at the top of Aztec pyramids, such as the Templo Mayor in Tenochtitlán. These sacrifices were conducted as part of religious rituals to ensure the sun's daily appearance and to instill fear as a display of power.
Aztec ball games were also held at the pyramids, but the losing team's captain giving themselves as a human sacrifice to the winning team was more associated with Mayan traditions and prosperity beliefs.
