A member asked:

When i cut my finger the blood was really thick and black looking what would cause my blood to be so thick and black?

A doctor has provided 1 answer

Venous blood: If you cut a venule or small vein, the blood is indeed dark, but on exposure to the air will soon turn red, so, don't worry, this is appropriate hematological activity.
