It meets oxygen
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.

The oxygen in it is replaced with carbon dioxide.
Because of the high amount of blood that circulates through the liver.
After blood is oxygenated, it turns from a dark maroon to a bright crimson color. The cell circulates around the body distributing oxygen to other cells before becoming depleted of oxygen and returning to the lungs to get more.
Their white and red blood cell drops causing anemia. No blood circulates around cells around the eyes?

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.
If you bleed dark brown blood when you cut your finger it means you are alive........ at least your body is.
The blood received by the right atrium is dark red because it is deoxygenated blood returning from the body tissues. Deoxygenated blood appears dark red due to the presence of deoxygenated hemoglobin.
