Human blood contains different types of cells (red blood cells, white blood cells, and platelets) compared to animal blood. Additionally, human blood is rich in hemoglobin, which carries oxygen, while some animals have other proteins that serve a similar function. The composition and structure of blood components also vary between human and animal blood.
Some flies, such as female mosquitoes and tsetse flies, drink blood as a source of protein for egg production. However, not all fly species drink blood; many feed on nectar, decaying matter, or other insect prey.

As a half-vampire, half-human hybrid, Renesmee's diet in Twilight consists of a mix of human foods and blood. She is able to consume human food like normal, but also has a thirst for blood like a vampire, although her bloodlust is not as strong as a full vampire's.
