Solution:

The penis contains three cylindrical masses of erectile tissue - two dorsal corpora cavernosa (B) and one ventral corpus spongiosum (A). These bodies are surrounded by fibrous tissue (C). During sexual arousal, the three bundles of tissue in the penis become engorged with blood. If the blood supply to corpora cavernosa is impaired, the erection will not occur.
