What is anemia?
Blood, as a prelude to the explanation of anemia, is a more human body tissue composed of cells as others but that is in liquid state precisely because of the very important role is to serve as a means of communication and transport of all substances necessary to maintain proper operation supplied and all our organs.
The cells that make our blood are basically:
Red blood cells, erythrocytes
They’re like bags filled with a protein called hemoglobin that is peculiar to join easily to certain gases such as oxygen and CO2 (carbon dioxide). Erythrocytes are continuously traveling through the circulatory impulse of the heart from the lungs where it picks up oxygen to the tissues where the cells require oxygen for metabolism and energy producers also need to get rid of their main metabolic waste product that is carbon dioxide (CO2). The oxygenation cycle begins as a red blood cell in the lung. There passage through the pulmonary capillaries receives oxygen. After that travels to different tissues. Upon reaching the capillaries of these tissues releases oxygen the red blood cells on cells with which they cross is at the same time the CO2 they give off. Upon returning the red blood to the lungs get rid of that CO2 to be eliminated in the breath thus being available again to relink oxygen and thus initiate a new cycle of oxygenation.
White blood cells
This group includes all the cells that defend against foreign agents that can damage our tissues such as viruses and bacteria, among others, when they find chance to infect. This group includes, for example, granulocytes (classified as neutrophils, basophils, and eosinophils), monocytes and lymphocytes basically.
Platelets
They are like tiles or bricks in charge of plugging the cracks that may appear in the blood vessels and which would escape the blood. They are essential to enable it to conduct the entire process of coagulation and thereby prevent us bleed when injured.
All these cells are born in the complex producing organ of blood cells is bone marrow, located within the bones of the trunk in a healthy adult. These cells are of limited life, so there is continual renewal of the same by the body and needs to occur every day hundreds of thousands to avoid any appearance of anemia, leukopenia (low white blood cells) or thrombocytopenia ( platelet deficiency).

I love these articles. How many words can a wosrmidth smith?
The very heart of your writing whilst sounding reasonable initially, did not settle well with me after some time. Someplace within the sentences you were able to make me a believer but just for a very short while. I still have a problem with your leaps in assumptions and you would do nicely to fill in all those gaps. If you can accomplish that, I would undoubtedly end up being impressed.
