Haemoglobin .
The blood of insects is typically colorless or pale yellow due to the lack of red blood cells found in vertebrates.
Erythropoietin, which is a hormone released by the kidneys, causes the creation of red blood cells in the bone marrow. These red blood cells are created from haemopoietic stem cells.
The heme group of the oxygen binding hemoglobin gives blood it's red color.
It's red - the same colour as human blood (and that of most other animals)
Erythrocyte is the medical term meaning mature red blood cell. In medical terminology Erythro = red, cytes= cells.Associated term:White blood cells are called Leukocytes, Leuko = white, cytes = cells.
You have hemoglobin in red blood cells. They are 'inside' the capillaries.
The protein "Hemoglobin" is responsible for the red color. Each hemoglobin molecule can bind up to 4 oxygen atoms. When fully loaded with oxygen atoms the protein takes on a more bright red color. When deprived of oxygen the protein takes on a darker red/blue color.
The substance responsible for the yellow color of urine is urochrome, a pigment produced during the breakdown of hemoglobin in red blood cells. The color of urine can also be affected by hydration levels and certain medications or foods.
Hemoglobin's ironRed blood cells contain hemoglobin, a substance which is rich in iron. The iron is bound to the hemoglobin molecules (the protein). The iron atom that is complexed by "haem" units is what gives the color. Iron is a transition element.
The blood of a lizard is typically red, just like the blood of other vertebrates. The red color comes from the presence of hemoglobin, a protein that carries oxygen in the blood.

Melanin is not the agent reponsible for coloring red blood cells. Melanin gives color to skin, parts of the eye, hair, the inner ear, the brain, and adrenal glands, though. The substance that makes the blood cells red is iron. It's actually a very pure form of 'rust'. Hemoglobin is also associated with red blood cell color.
