The first picture is pith, that is the very center of the tree. The second picture is beetle damage. The third picture is rot. In framing lumber the pith is generally not a problem unless the juvenile wood around it is causing excessive warp. A few beetle holes are not a problem unless so severe as to weaken the board. Rot can be a problem as it will significantly weaken the framing member. Ways to avoid these defects is to look for them when buying and reject those boards. When they show up in lumber you have brought home, try to cut out most of the problems, Set aside any defective boards and use them for the shorter stuff like cripples and headers, where you can cut out problems.
