Morphology

external + carotid

The meaning is a straightforward composition: 'external' (outer) modifies 'carotid' (the carotid artery), yielding the outer/externally directed branch of the carotid. This morphological logic is literal and cross-linguistically common (e.g. Spanish 'carótida externa'), so a learner who knows both constituents can infer the MWE meaning.

Etymology

External carotid comes from two parts: external meaning 'outside' and carotid from a Greek word meaning 'to make sleepy', because pressing the neck artery could make someone faint. The name fits because the external carotid is the branch of the main carotid artery that goes to the face, tongue and other outer parts of the head.
