What vessels primarily supply blood to the bladder?

The blood supply to the bladder is primarily derived from the superior and inferior vesical arteries. These arteries branch from the internal iliac artery, which is a major vessel that supplies blood to the pelvic organs. The superior vesical artery typically supplies the upper part of the bladder, while the inferior vesical artery (in males) supplies the lower part of the bladder and the surrounding structures.

The celiac trunk mainly supplies the foregut structures and does not directly supply the bladder. The femoral artery primarily provides blood to the lower limb, and while it may have some collateral circulation, it is not a primary source for the bladder. The descending aorta supplies blood to the abdominal and pelvic regions but does so indirectly; it branches into the common iliac arteries, which then form the internal iliac arteries that give rise to the vesical arteries.

Thus, the superior and inferior vesical arteries are specifically designed to meet the vascular needs of the bladder, making this answer the most accurate in the context of blood supply to this organ.
