Blood appears dark red as it circulates through the body primarily in the veins, where it is deoxygenated. This occurs after oxygen is delivered to the tissues and carbon dioxide is picked up, resulting in a lower oxygen content. The dark red color is due to the altered state of hemoglobin, which reflects different wavelengths of light depending on its oxygen saturation.

Can dark matter enter a humans body?
The whole point of dark matter is that it doesn't interact via the electromagnetic force (that's what makes it "dark"). It's therefore largely unaffected by normal matter (except through gravity), and could go straight through your body... or a lead wall, or the Earth... without you even noticing. In fact, if dark matter really exists, that pretty much has to be happening all the time.

Why does blood circulate around the body?
Blood flows away from the heart in the arteries, and towards the heart in the veins. It cannot travel in two directions through one vessel. Blood goes away from the heart in arteries, exchanges its oxygen for waste in the capillaries, and then goes back to the heart through the veins. Valves in the veins keep the blood from flowing in the wrong direction.
