Final answer:
The superficial and deep external pudendal arteries supply blood to the skin and fascia of the lower abdomen, external genitalia, and medial aspect of the thigh, with the superficial artery catering to skin and the deep artery supplying deeper structures.
Step-by-step explanation:
The superficial external pudendal artery and the deep external pudendal artery are branches that originate from the femoral artery, which is itself a continuation of the external iliac artery. Their primary function is to supply blood to the skin and fascia of the lower abdomen, the external genitalia, and the medial aspect of the thigh.
The superficial artery typically supplies the skin, while the deep artery, being smaller, penetrates to supply the deeper structures.
