Genitals
Due to the amount of blood that is pumped, the vagina becomes more swollen, since the clitoris is largely responsible for sexual pleasure and in men, the penis may be up to 17 times greater with erection. However, the hormone Oxycontin, considered responsible for the pleasure (and not only, of course) is released during orgasm promoting uterine contractions and in the case of men, the contraction of the seminiferous tubules (where sperm are produced) and semen ejection .
Muscles
It is undoubtedly an excellent exercise, improving your flexibility and strength. During orgasm the woman may have muscle contractions in the vagina, on the thighs, butt and abdomen and the man in the prostate region, these sensations which further intensify the pleasure. However, some cramping may arise due to contraction and expansion of the muscles, this is because there is a significant amount of CO2 released.
Brain
Contrary to what one might think, it is he who commands the whole operation. It produces dopamine, a hormone linked to desire and that "negotiates" pleasure in the brain, encourages the production of adrenaline and communicates with the genitals regarding the control of stimuli.
Heart
Already felt fast right ?! Well, the rate can go up to 190 beats per minute due to muscle tension stimulated by adrenaline. This double heartbeat is to give energy to the muscles.
Breath
It's probably the one note that there is an immediate change. The same gets deeper and accelerated even from 14 to 20 breaths per minute, since the lung needs to work harder to ensure the last energy to muscles.
