Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.. Red blood cell size relative to the animal also differs between species. Red blood cells have no nucleus, because most of their bulk is made up of hemoglobin, a compound that carries gases, such as oxygen and carbon dioxide. Most animals, besides mammals, have nuclei in their mature red blood cells.Mature mammalian red blood cells lose their nucleus and organelles in order to carry more hemoglobin, and they do not need to use any oxygen themselves. It has sometimes been called a fluid “tissue,” because like solid tissues it contains several types of cells which perform complex functions for the human body. The color of blood is related to the compounds that transport oxygen. White Blood Cells in Animals. All cells need a nucleus for replication and maturation.
