The integration block in simulink

[pixel01]

Hi every body,

I am not sure if this question is suitable in this box, so I will have a try.
I just started to study Matlab and Simulink. There's one thing i do not understand:
Why does the integration block in simulink have the symbol 1/s. Does it have something linked with laplace transform?

Thanks for reading.
