What vessels primarily supply blood to the bladder?

The primary blood supply to the bladder comes from the superior and inferior vesical arteries. These arteries branch off from the internal iliac artery, which is the main artery supplying the pelvic region, including the bladder. The superior vesical artery supplies the upper part of the bladder, while the inferior vesical artery supplies the lower part, especially in males, and also provides branches to the prostate and seminal vesicles.

In contrast, other options do not directly supply blood to the bladder. The celiac trunk primarily supplies the foregut structures such as the stomach, liver, and spleen. The femoral artery is primarily responsible for supplying blood to the thigh and leg, rather than pelvic organs. The descending aorta supplies blood to the abdomen and lower body but does not provide direct branches that supply the bladder. Therefore, the vessels that are correctly identified as supplying the bladder are indeed the superior and inferior vesical arteries.
