Hepatic artery blood supply

The term "Hepatic artery blood supply" refers to the anatomical and physiological process by which oxygenated blood is delivered to the liver via branches of the hepatic artery system. The main vessel involved is the proper hepatic artery, a branch arising from the common hepatic artery (itself a branch of the celiac trunk), which further divides into right and left hepatic arteries supplying respective lobes of the liver[1][3][5]. This arterial system provides approximately 25–30% of total hepatic blood flow but supplies most of its oxygen content; the remainder comes from portal venous inflow[1][6][7]. Within clinical and pharmacological contexts, "hepatic artery blood supply" is not considered a molecular or therapeutic target such as an enzyme, receptor, transporter, or ion channel. Instead, it describes an anatomical vascular pathway essential for normal organ function and relevant in surgical planning (e.g., transplantation) or interventional radiology (e.g., chemoembolization)[1][4]. Variations in this anatomy are common and can impact procedural risk[2][4]. Because this entry does not refer to a discrete molecule or receptor but rather an anatomical feature/process, it should be flagged as incorrect for structured molecular target databases.
