Morphology

branchial + arch

The compound directly combines 'branchial' (related to gills) with 'arch' (an arched structural element), so if a learner knows both constituents they can infer it refers to an arched bony/cartilaginous support for gills. This is a compositional anatomical term common across languages, making the meaning transparent from its parts.

Etymology

Branchial arch comes from branchial, meaning 'gill', and arch, so it paints the picture of a small curved 'bridge' that holds a fish's gills. So today branchial arch means one of the curved bones or softer supports that hold and protect a fish's gills.
