How a red blood cell is adapted
WebRed blood cells have adaptations that enable them to carry a maximum amount of oxygen: They contain the protein haemoglobin , which gives them their red colour, at the lungs. The vast majority of vertebrates, including mammals and humans, have red blood cells. Red blood cells are cells present in blood to transport oxygen. The only known vertebrates without red blood cells are the crocodile icefish (family Channichthyidae); they live in very oxygen-rich cold water and transport oxygen freely dissolved in their blood. While they no longer use hemoglobin, remnant…
