Are there blood vessels in the bladder?

Yes, there are blood vessels in the bladder. The bladder is a muscular organ that stores urine. It is supplied by several blood vessels, including the superior vesical artery, the inferior vesical artery, and the middle vesical artery. These arteries branch into smaller vessels that supply the bladder with oxygen and nutrients. The bladder is also drained by several veins, including the superior vesical vein, the inferior vesical vein, and the middle vesical vein. These veins carry deoxygenated blood from the bladder back to the heart.
