Common Iliac Arteries: Vital for Pelvis and Limb Blood Supply
The common iliac arteries, a pair running along the pelvis, play a crucial role in our circulatory system. They branch off from the aorta, our largest artery, at the lumbar spine's fourth vertebra.
Starting at the aorta's end, the common iliac arteries, one on the right and one on the left, travel towards the pelvis. At the pelvic inlet, they split into the internal and external iliac arteries. The internal iliac artery nourishes the pelvic organs, while the external iliac artery becomes the femoral artery, supplying blood to the leg, including the thigh, knee, and area below the knee.
The left common iliac artery begins at the aorta's bifurcation, roughly at the level of the fourth lumbar vertebra (L4). This crucial artery ensures blood reaches the lower limbs and pelvic organs.
The common iliac arteries, originating from the aorta and branching into internal and external iliac arteries, are vital for blood supply to the pelvis and lower limbs. Their correct functioning is essential for our overall health and mobility.
