Document Summary

Sexual response typically progresses in three stages, excitement, orgasm, and resolution. Vasocongestion: an accumulation of blood in the blood vessels of a region of the body, especially the genitals, a swelling or erection results. Excitement: the first stage of sexual response, during which erection in the male and vaginal lubrication in the female occur. Erection happens when the corpus cavernosa and the corpus sponginosum fill with blood. Erection occurs when the main arteries that supply the penis with blood fill, and the veins constrict restricting outgoing blood flow. Erections do not last forever, so the opposite process happens when the erection disappears, also the transmitters norepinephrine and epinephrine are involved. An important response for women is lubrication. This is also caused by vasocongestion, there is increased blood flow to the walls of the vagina, and the lubrication is from the semipermeable membranes f the vagina.
