Air is conducted through smaller and smaller bronchioles for about 15-20 generations, and collectively they're known as conducting bronchioles, receiving O2 from bronchial arteries.
Plaque building up in the coronary arteries, so the ones that transport oxygen-rich blood around the heart, can over time cause a blood clot to form, which cuts off some of the heart muscle and causes it to die.
Sexual arousal triggers the parasympathetic reflex that causes arterioles in the external genitalia to dilate and fill with blood, which is actually one of the only times the parasympathetic system controls any arteriole action.
In this form, the great arteries still connect to the wrong ventricle, but it's just that the ventricles are the one's that switch places along with their atrioventricular valves.
This is because the part of the occipital lobe in charge of the macula gets blood from both the posterior cerebral artery as well as the medial cerebral artery.
Plus, if you have cholesterol plaques in your arteries, then you probably have them in your coronary arteries, which carry oxygen and nutrients to the heart muscle itself.
Most neural responses like this use baroreceptors, special nerve endings found in the carotid arteries, the aorta, and other larger arteries in the neck.
