Can you help me identify these two parts?

[PIZZABYSTORMED]

2005 Volvo s40 t5 AWD
Replacing head gasket, timing belt and misc items
I'm past the halfway point and will be closing it soon. However there's two areas I may be missing items/ parts. Hence my request for your assistance. Here are a few pictures (they're probably rubber/ metal coolant/ vacuum lines)
1) what attaches to the metal tube on the head?
2) what attaches to the rubber hose behind the block?

Help me identify these missing components, I'm surprised I lost them.
