Internal pudendal artery
The internal pudendal artery serves oxygenated blood to the external genitals. This includes both males and females. However, due to gender, there are some anatomical differences. The artery tends to be smaller in women. Also, some of the branches of the artery may be specific to gender. Males have a both a dorsal and deep artery of the penis, while females have a dorsal and deep arteries of the clitoris. Also, there are differences in the posterior labial and scrotal branches, as well as other vessels specific to the genitals. Yet, the inferior rectal and perineal arteries are the same in both sexes. The internal pudendal artery itself branches from the internal iliac. Also, a blood vessel should not be mistaken for the internal pudental vein. Once blood becomes deoxygenated, the internal pudental vein assists in draining it back to the internal iliac vein in the pelvis. Ultimately, all deoxygenated blood flows back to the lungs and the chambers of the heart. Once there, it is reoxygenated, before it is subsequently recirculated throughout the body.
