Penis anatomy. Illustration of a sectioned view of an erect penis, the male urogenital organ. The penis is in an erect state. The internal tissues of the penis are shown, including the corpora cavernosa (red) and the corpus spongiosum (pink), the latter surrounding the urethra (yellow tube). The urethra is used in urination and also in ejaculation. The corpora cavernosa fills with blood during an erection. Arteries (red), veins (blue), and nerves (yellow) are also shown. | |
