The amount of blood in the penis increases sixfold during an erection. The blood filling the corpora cavernosa compresses and then closes off the openings to the veins that normally drain blood away from the penis (see Figure 4). In essence, the blood becomes trapped, maintaining the erection.
Blood also may come from the nose, the back of the throat, or part of the gastrointestinal tract. When blood originates outside of the respiratory tract, the condition is known as pseudohemoptysis.. Vomiting up blood, medically known as hematemesis, is one type of pseudohemoptysis.
