Also asked, does a vent stack have to go straight up?
Normally they run level or plumb, unless there is an obstacle to work around. Vent pipes must be installed so they stay dry. This means that they should emerge from the top of the drainpipe, either straight vertically or at no less than a 45-degree angle from horizontal, so that water cannot back up into them.
Likewise, how many bends are in a vent pipe? You can install 90-degree bends in vent pipes.

This means that there are bends or connections in the other piping and this piping needs to attach to the venting system.
