There are basically two possible situations: network interfaces attached to different networks and network interfaces attached to the same network.
If the network interfaces are attached to different networks, the routing table controls what is sent using which interface. The contents of the routing table may or may not be further controlled by routing protocols (RIP, OSPF, EGP, ...). This is like it is in every IP-host.
If there are several interfaces pointing into one network, per default Solaris employs all the interfaces using a round-robin algorithm, if i remember correctly.
It is also possible to configure several interfaces into the same network to form aggregated links: etherchannels, configured for either additional bandwidth or high-availability (or both), etc..
I hope this helps.
