About the Life Magnified Set: These 20 stamps were issued to showcase life undetectable by the human eye alone. All 20 stamps picture photographs taken using special techniques and the aid of a microscope. The set celebrates the beauty and complexity of microscopic organisms and parts of organisms, the study of which have had various impacts on humans.
History the stamp represents: Red blood cells (formally known as erythrocytes) have one of the most important jobs in the human body. They contain hemoglobin, a special protein that allows them to transport oxygen from the lungs to the rest of the body. Hemoglobin gives the cells their bright red color.
When looking at a red blood cell under a powerful microscope, it appears as a disk with an indent in the center. Interestingly, while most cells have nuclei, red blood cells lack this structure. This quality is what allows them to be flexible and change shape as they travel through the blood stream.
Red blood cells are formed in the bone marrow. A normal number of these cells per microliter of blood is 4.7 to 6.1 million in men, 4.2 to 5.4 million in women, and 4 to 5.5 million in children. A number outside this range is a result of some kind of blood condition, including cancer or vitamin deficiencies (low count) or polycythemia vera (high count).
The most important thing to do to keep your red blood cells in ship-shape is eat a healthy diet. Iron, folic acid, and vitamin B12 are especially critical. These come from red meat, dark green vegetables like kale and spinach, legumes like lentils and beans, and more. Without red blood cells, our bodies would not be able to use the much-needed oxygen to survive.
