How to understand wireshare packages?

Question

Wireshark

Good afternoon. As a result of studying sniffing, namely, wiretapping of data transfer between me and one site written in flash, I saw that every few seconds there are packets in the tcp protocol, but I don’t understand how to understand what exactly they are transmitting. Can anyone come across such problems, tell me how to find out what exactly they are transmitting ???
