Which artery is NOT typically classified as low resistive?

The aorta is classified as a high-resistance artery due to its role and the pattern of blood flow it supports. High-resistance arteries typically supply organs or tissues that do not have a constant blood flow requirement, such as skeletal muscles during periods of lower activity. The aorta, being a primary conduit for blood from the heart to the rest of the body, experiences fluctuating flow depending on the cardiac cycle, especially during systole and diastole.

In contrast, the renal artery, celiac artery, and hepatic artery are classified as low-resistance vessels. Low-resistance arteries supply organs that require a steady, consistent blood flow regardless of the body’s activity levels, such as the kidneys (renal artery) for filtration, the celiac artery which supplies blood to the stomach and other abdominal organs, and the hepatic artery that provides oxygenated blood to the liver. These arteries maintain more constant diastolic flow, reflecting their role in supporting vital organs and tissues that continuously require blood supply.
