For 10 points, name these cells that contain hemoglobin and carry oxygen.
During inflammation, these cells form stacks called rouleaux. Nuclear remnants called Howell-Jolly bodies in these cells can indicate that the organ that destroys them is failing. High levels of these cells cause polycythemia, and young examples of them are called (*) reticulocytes. The Coombs test is used to determine whether their count is low, and a valine to glutamic acid point mutation in these cells causes a notable condition. These cells don't have a nucleus and are affected in sickle-cell anemia. For 10 points, name these cells that contain hemoglobin and carry oxygen.
