Why pennis is enriched with blood vessels |
| Answer» During an erection, the arteries expand to increase\xa0blood\xa0flow to the\xa0*****. The\xa0blood\xa0fills two tubes of spongy tissue in the\xa0*****\xa0(corpus cavernosa). This causes them to swell, making the\xa0*****\xa0larger and stiff, so it angles out from the body. The\xa0veins\xa0narrow, which traps the\xa0blood\xa0and maintains the erection. | |
