I've been feeling uncomfortable lately, and I don't know what's going on. The bleeding is not red. Went to consult the doctor, the doctor helped me answer the question. Now let me tell you what happened.

Blood is not red. What's going on

Reason 1: the venous blood of ordinary people is dark red, not like arterial blood is bright red, because arterial blood pressure, high oxygen content, this is normal, there is nothing to worry about.

Reason 2: when oxygen is lacking, the oxygen combined with hemoglobin is reduced, and the color will turn black and purple. Cyanosis occurs in the skin, lips, nails, etc.

Reason 3: another reason is anemia. When anemia occurs, hemoglobin decreases, so the color of the blood becomes lighter and less red.
