PATHOLOGY

Detailed explanation-1: -During an erection, the arteries expand to increase blood flow to the penis. The blood fills two tubes of spongy tissue in the penis (corpus cavernosa). This causes them to swell, making the penis larger and stiff, so it angles out from the body. The veins narrow, which traps the blood and maintains the erection.

Detailed explanation-2: -Common signs of erectile tissue damage include pain, swelling, erectile dysfunction and curved erections. If you injure your penis, it’s important to seek medical help to find out what’s going on inside the tissue and, if appropriate, get prompt treatment to prevent complications.

Detailed explanation-3: -The erectile tissue of the human penis is composed of elastic fibers, collagen fibers, smooth muscles, arteries and veins, and has important functions in the mechanism of penile erection [1]–[6].
