Final answer:
The uterus and ovaries receive blood supply from the ovarian artery, gonadal artery, and internal iliac artery. In females, the internal iliac artery also supplies blood to the uterus and vagina. The ovarian artery supplies blood to the uterus, ovaries, and uterine tubes.
Step-by-step explanation:
The uterus and ovaries receive their blood supply from multiple arteries. The ovarian artery, a branch of the abdominal aorta, supplies blood to the uterus, ovaries, and uterine tubes. It is located within the suspensory ligament of the uterus. In addition, the gonadal artery also supplies blood to the reproductive organs, and can be described as either an ovarian artery or a testicular artery, depending on the sex of the individual.
On the other hand, the internal iliac artery, a branch from the common iliac arteries, provides blood to the pelvic area, including the bladder, walls of the pelvis, external genitalia, and the medial portion of the femoral region. In females, it also provides blood to the uterus and vagina. The uterine artery and vaginal artery, both branches of the internal iliac artery, distribute blood to the uterus and vagina respectively.
