It loses oxygen!
the blood cells begin to break apart so it eventually turns a shade of brown
No , It Does Not Turn Dark - sillysarahbugg . message me on my board .
Red blood cells need oxygen. Oxygen is what gives blood that bright red color. When blood is lacking oxygen, it turns dark and that's why people turn purple or blue.
It is the same reason a person's blood turns black when it is on the outside of the body. When blood cells are exposed to the air, they become deoxygenated, dry up and turn dark.
no at least not under normal conditions.
Oxygenated blood is bright red; deoxygenated blood is dark red.
They turn purple and die
Dark blood is blood from which the oxygen has been depleted. Once it is filled with oxygen again (in the lungs), it becomes lighter in color.
it would turn a dark color green
Exercise sends antibodies and white blood cells (the body's defense cells) through the body at a quicker rate. As these antibodies or white blood cells circulate more rapidly, they could detect illnesses earlier than they might normally. The increased rate of circulating blood may also trigger the release of hormones that "warn" immune cells of intruding bacteria or viruses.
Plasma Cells are, in fact White Blood Cells - they are a special group of Lymphocytes. Plasma Cells are also known as "Effector-B Cells" and are activated by the presence of antigens in the body
One microliter of blood contains approximately 5 million red blood cells.
