Facts About The Blood

Every person has five to six liters of blood, depending on their size and weight; it makes up six to eight percent of our body weight
the red blood cells transport oxygen to all tissues and organs of the body, and the transport of carbon dioxide from tissues and organs towards the lungs also takes place in this way
Another important task of the blood is to transport nutrients and hormones into the cells
The blood turns red due to iron, which is contained in the blood pigment (hemoglobin) of the red blood cells
A lot of information about organ functions and diseases can be obtained by taking a blood sample

What is a Blood? What is The Blood Made of?

The blood consists of liquid and solid parts. The liquid part is called blood plasma. Which makes up about 60 percent of the blood. The following important components are found in the blood plasma:

Clotting factors
numerous metabolic products
Antibodies
Hormones

If the coagulation factors have been removed from the plasma, it is called blood serum.

The remaining 40 percent of the solid part of the blood is made up of cells. This includes:

red blood cells ( erythrocytes ): carry oxygen and carbon dioxide and define our blood group
White blood cells ( leukocytes ): are defense cells and therefore part of the immune system

The following terms are often found on the laboratory results:

Reticulocytes
Lymphocytes
Monocytes
Granulocytes

Laboratory Values For Everything To Do With Blood

In the laboratory, the components of the blood can be separated from one another and examined.

The small blood count determines, among other things, the number of red and white blood cells and platelets. The analysis can point to various diseases, inflammations or deficiency symptoms.

In the complete blood count, the different types of white blood cells are also examined in detail.

When examining the blood, for example, these laboratory values play a role:

Hemoglobin (Hb)
Hematocrit (Hk)
Ferritin
Transferrin
Mean Corpuscular Volume (MCV)
Haptoglobin
Erythropoietin (EPO)

Forms of Anemia

One of the diseases that is directly related to the blood is anemia. This can occur if there is too little red blood pigment (hemoglobin) and/or red blood cells (erythrocytes) and thus too little blood cells (hematocrit) in the body. You can find more information on various forms of anemia under the links below:
