A blood cell is any cell of any type normally found in blood. In mammals, these fall into three general categories: Human blood smear: a - erythrocytes; b - neutrophil; c - eosinophil; d - lymphocyte. ... Subclasses Allotheria* Order Multituberculata (extinct) Order Volaticotheria (extinct) Order Palaeoryctoides (extinct) Order Triconodonta (extinct) Prototheria Order Monotremata Theria Infraclass Marsupialia Infraclass Eutheria The mammals are the class of vertebrate animals characterized by the production of milk in females for the nourishment of young, from mammary glands present on most species...

What is Blood? from the Genetic Science Learning Center at the University of Utah.
Not every cell you see in the lab will look exactly like these, but if you look for the features pointed out with each micrograph, you should be able to make proper identifications during differential white bloodcell counts or during a lab exam.
The background cells in this micrograph are erythrocytes (red bloodcells).
The primary function of these cells is to carry oxygen from the lungs to the body cells.
Red bloodcells are the most common type of bloodcell and are the vertebrate body's principal means of delivering oxygen from the lungs or gills to body tissues via the blood.
The blood plasma is straw-colored alone, but the red bloodcells change colors due to the state of the hemoglobin: when combined with oxygen the resulting oxyhemoglobin is scarlet and when oxygen has been released, the resulting deoxyhemoglobin is darker, appearing bluish through the blood vessel walls.
Spherocytosis is a genetic disease that causes a defect in the red bloodcell's cytoskeleton, causing the red bloodcells to be small, sphere-shaped, and fragile instead of donut-shaped and flexible.
