It contains the molecule hemoglobin which gives blood its characteristic color. The hemoglobin contains Iron and is responsible for transporting Oxygen in the blood.
The Volturi have red eyes because they choose to drink human blood, despite not being newborn vampires. Their diet of human blood results in their eyes remaining red, rather than transitioning to a golden hue like vampires who feed on animal blood.
Red! Any vampire that feasts on human blood has red eyes!
When red blood cells die, other red blood cells come in and multiply.

The shape of the human red blood cells is that it is biconcave in shape.
Red blood cells are made in the red bone marrow.
Red blood cells in the human body are normally contained within the blood vessels. They may be stored in the spleen, and are produced in the red marrow.
The darker blood is older blood while the red is newer.
You can find red blood cells, white blood cells, and platelets in human blood.
Bovine red blood cells are slightly larger with a diameter of about 6-8 μm compared to human red blood cells, which have a diameter of about 6-7 μm. The concentration of red blood cells in bovine blood is lower than in human blood, with a hematocrit of around 30-35% for cows compared to 40-50% for humans.
Frogs have nucleated red blood cells, whereas humans have anucleated red blood cells. This means that frog red blood cells contain a nucleus, while human red blood cells do not. Additionally, frog red blood cells are elliptical in shape, while human red blood cells are biconcave disks.
1) Frog's red blood cells contain a nucleus that carries all the genetic information needed to make new cells by replication. Human red blood cells contain no nuclei because they reproduce differently than frog. 2) We human have platelets in our blood but frogs do not have them.
