Before proceeding to determine the meaning of the term at hand, it is important to know its etymological origin. Thus, it should be stressed that this is composed of two words that emanate from Latin:
• Globule, comes from "globulus", which can be translated as "small organic sphere".
• Red, meanwhile, comes from the word "russus", which means red.

Blood cell is the diminutive balloon . The term refers to a small spherical body . The most common use of the globule concept is linked to the cells that make up the blood : in this sense, we can talk about Red blood cells and white blood cells .

The Red blood cells , also known as erythrocytes or red blood cells , are red globose cells . Together with the white blood cells and platelets, they make up the group of form elements of the blood. It can be said that red blood cells are the most numerous component of the elements.

The women they have about 4,500,000 red blood cells per cubic millimeter of blood, while the mens They have about 5,000,000. When the values ​​move away from these figures, the organism presents some kind of abnormality.

In addition to the above, it is common for people, due to certain health circumstances, to undergo tests that have as a clear objective to know the status and number of their red blood cells. Hence, for example, what is known as a red blood cell count, which measures the amount of these and is done through a simple blood draw.

Thanks to this test, it can be determined, among other things, if the person in question has anemia, a bone marrow disorder called myelofibrosis or Alport syndrome, among other conditions.

There are a number of situations that can cause the amount of red blood cells in an individual to be altered. Thus, for example, it is established that this may be lower than normal due to anemia, bleeding, malnutrition, leukemia, pregnancy and even the intake of certain medications such as those used in treatments Chemotherapeutic

On the other hand, the number of red blood cells may be above normal due to smoking or congenital heart disease, among other options.

The red blood cells, which lack nucleus and mitochondria, harbor the hemoglobin inside. This means that the red blood cells are responsible for carrying oxygen to the rest of the cells and tissues of the body . Thanks to its flexible membrane, erythrocytes can pass through the narrowest capillaries, where they release oxygen.

It is possible to notice changes in size, shape and color in red blood cells. The anisocytosis , for example, involves the coexistence of erythrocytes of different sizes in the same blood sample. The microcytosis (linked to anemia), the macrocytosis (related to the consequences of alcoholism) and megalocytosis They are other disorders of the size of red blood cells.

As for the changes in form, you can identify the acantocytosis (produced in liver cirrhosis), the echinocytosis (uremia) and the keratocytosis (hemolysis), among other alterations, while color changes involve disorders such as anisocromía and the polychromasia .
