Within our body, numerous processes of a physiological and biochemical nature occur, such as diapedesis, which fulfill vital functions in the organism. Each piece and process is essential to maintain a harmonious balance, and one of the essential elements for this balance is blood, a crucial fluid that circulates through our body.

This blood fluid is made up of different complementary components that contribute to its functions. In this way, each element has its own value, including blood fluid and then we will explain what it is and what its function is in our blood vessels.

Definition and concept of blood fluid

Blood contains several components that allow it to fulfill its function in the body. One of these components is the hematic fluid, which has the ability to transport oxygen and nutrients through the blood plasma, especially to the tissues, also taking care of eliminating waste. Blood circulates to various places in the body through different blood vessels, such as arteries, veins and capillaries.

This concept encompasses all elements that make up bloodsuch as the various blood cells (red blood cells and white blood cells or leukocytes) and other essential components. All this is wrapped in a plasma known as blood plasma.

Some elements, such as leukocytes, are only present temporarily to fulfill their function intermittently. Besides, blood plasma is related with the serous or serohematic fluid, which is characterized by its pale yellow color.

In summary, blood, along with blood fluid, plays a systematic role in containing its properties in blood vessels and distribute them throughout the body. This process is known as blood circulation and is closely related to the vital nature of blood.

What is a blood fluid used for?

Blood, as tissue, fulfills various vital functions in the body, such as regulating body temperature and transporting hormones through the vessels. Its role is essential in the area of ​​medicine and health, since blood fluid cannot be artificially manufactured despite current technological advances.

Blood donation is one of the main uses of this component, thanks to volunteers who allow to treat oncological diseases and carry out organ transplants. Blood is essential for the functioning of the body, allowing other systems to carry out their functions and tasks normally.

In addition, it sends antibodies to fight diseases and its coagulation helps heal damaged tissues. As it travels through the circulatory system, blood carries waste materialsas carbon dioxide, to the lungs, kidneys, and digestive system for elimination from the body.

What are the characteristics of a hematic fluid?

Although it may seem contradictory, the blood fluid is made up of two parts: a liquid and a solid. The first is plasma, which can represent up to half of the total volume of the human body, while the solid part is made up of white blood cells, red blood cells, and platelets.

Venous blood is dark red in color, while arterial blood is lighter. This difference in tonality due to the presence of hemoglobin, a natural pigment found in red blood cells. Texture-wise, it is considered a non-Newtonian liquid, which means that its viscosity varies with temperature and applied stress.

Although the composition of the blood can vary about 91% of its content is water. Under normal health conditions, its temperature can reach 37 degrees Celsius.

Because not all blood is the same, there are four blood groups that are determined entirely by genetics. These groups are A, B, AB and O, the latter being the most common. Group “O” is considered the ‘universal donor’ and can be used in surgeries for people of any other blood group.
