What vessel becomes the common femoral artery in the groin region?

In the groin region, the common femoral artery is formed from the continuation of the external iliac artery as it passes underneath the inguinal ligament. The external iliac artery is a continuation of the common iliac artery, which bifurcates at the level of the pelvic brim. Once the external iliac artery reaches the inguinal ligament, it transitions into the common femoral artery, which supplies blood to the lower extremity.

Understanding the anatomy of the vascular system is crucial for identifying the correct blood vessels involved in arterial supply. The deep femoral artery branches off from the common femoral artery and does not become the common femoral artery. The internal iliac artery primarily supplies the pelvic region and does not play a role in the formation of the common femoral artery. The inferior mesenteric artery supplies blood to the colon and is not associated with the lower extremities or the transition to the common femoral artery.
