femoral
common iliac arteries
common iliac arteries
The descending aorta divides near the brim of the pelvis to form the common iliac arteries. These arteries further branch into internal and external iliac arteries to supply blood to the pelvis and lower extremities.
Internal iliac artery
Blood from the lower extremities, blood flows through the common iliac vein. From the common iliac vein, the blood flows into the inferior vena cava on its way back to the right atrium of the heart.
The internal iliac artery and its branches are the main source of blood supply for the muscles and organs in the pelvis.
The common iliac vein carries deoxygenated blood from the lower limbs and pelvic region back to the heart. It joins with the external and internal iliac veins to form the inferior vena cava, which delivers the blood to the right atrium of the heart.
the pelvic organs
Blood goes into the Aorta from the heart. Then enters into Common iliac arteries, external iliac arteries, femoral artery, popliteal artery, and then it goes into the anterior tibial and posterior tibial arteries which supply the foot.
The external iliac vein drains into the common iliac vein as it enters the pelvis.
There are various kinds of blood vessels: *Arteries **Aorta (the largest artery, carries blood out of the heart) **Branches of the aorta ***carotid artery ***subclavian artery ***celiac trunk ***mesenteric arteries ***renal artery ***iliac artery * Veins **Large collecting vessels ***subclavian vein ***jugular vein ***renal vein ***iliac vein **Venae cavae (the 2 largest veins, carry blood into the heart)
