Why blood red in colour?
The hemoglobin in the blood goes red when it absorbs oxygen. Blood is not always red, if it is lacking in oxygen, it is infact blue. If you look at the veins in your arm or hand, they do not have much blood and therefore will be blue. You will never see blue blood because if you cut yourself, the blood is exposed to the air, allowing it to be oxygenated and thus turning it red.

Where does the oxygen from air mix with blood?
Air will not touch your blood until it is release to outside the skin. In most veins at least. Wren oxygen touches the blood, it turns red, but normally is blue. Oxygen may be circulating in your veins, but will not mix with the blood cells. The above is only half true. Oxygen mixes with your blood in the capillaries inside your lungs. The blood then transfers over to your arteries where it travels the body to deliver the oxygen to your muscles and other organs.

What is the difference between blue blood and red blood?
red blood is oxegenated; it has oxygen in it blood blood is not oxygenated; it does not have oxygen in it Arteries have red blood in them; they go to muscles so the muscles can use the oxygen, Veins have blue blood in them; they go back to the heart to go to the lungs to get oxygen when you get cut, even in a vein, the blood is red because when the blood comes out it becomes oxygenated. Although, when an artery gets gut it is bright red, although when a vein gets cut it is dark red. JACOB PONTOW IS A BEAST ^ who the heck is he?
