What does arterially mean?
"Arterially" is the adverbial form of "arterial", used to indicate that something happens by way of the arteries or in a manner connected with them. It appears overwhelmingly in medical and scientific writing, where clinicians describe drugs, contrast agents, or blood being delivered or measured arterially rather than intravenously or through other routes. For example, a radiologist might note that chemotherapy was administered arterially to concentrate treatment at a tumor's blood supply. The word carries a precise, clinical register and has no real place in casual conversation. It derives ultimately from the Greek "arteria", the term ancient anatomists used for the vessels they believed carried air, later refined into the Latin "arteria" that gave English both "artery" and "arterial". Though rare outside specialist literature, it is unambiguous and valuable wherever the route of delivery matters most.
adverbIn a manner relating to the arteries; by way of the arteries.
- By way of, or in a manner relating to, the arteries.
"The drug was delivered arterially to ensure it reached the tumor directly."
"The contrast agent was injected arterially to visualize the blood supply to the liver."
"Blood pressure is monitored arterially during the procedure using an inserted catheter."
Though built from one of medicine's oldest words — Greek 'arteria', which ancient anatomists believed carried air — 'arterially' is a modern clinical coinage found almost exclusively in medical writing.

Etymology of arterially
"Arterially" is formed from "arterial", the adjective derived from the noun "artery", combined with the adverbial suffix "-ly". The ultimate source is the Greek "arteria", adopted into Latin as "arteria" and thence into English. Ancient Greek anatomists applied the word to the vessels they believed contained air, and the modern sense of arteries as blood-carrying vessels developed over subsequent centuries. The adjective "arterial" arose in English in the early modern period, with the adverb following as a specialized medical formation.
