The corpus cavernosa refers to a region in the sexual organs of both males and females that fills with blood when aroused and erect. The penis has two of these regions, which is collectively referred to as corpora cavernosa.
In women, the corpus cavernosa is located in the clitoris. These regions fill with blood when they become erect. They go back to normal once the person has an orgasm or when the source of stimulation is removed.
