How do Human Blood Cells Differ from Animal Blood Cells?
Many animals, including all vertebrates, have essentially the same blood cells as human blood cells. Other types of circulatory systems, such as those in arthropods and mollusks, are not properly blood, but do share some similarities. Humans and other vertebrates have three types of blood cells, red blood cells or erythrocytes, white blood cells or leukocytes, and platelets or thrombocytes. Animals with an open circulatory system have hemolymph, a fluid combining blood and interstitial fluid, rather than blood, and it contains only one type of cell, hemocytes. Hemocytes, like the leukocytes of humans and other animals, are part of the immune system. They are phagocytic cells that ingest foreign particles and pathogens and serve in signalling within the body. Animals with hemolymph use hemocyanin instead of hemoglobin to transport oxygen. Human blood cells are very similar to those of other animals, though there are a few interesting differences. Both animal blood cells and human blood
