Blood boiling point. Composition and properties of blood. Deadly temperature

Can blood boil right in the body? An interesting question that we will try to answer in this article.

Blood is a fluid mobile connective tissue of the internal environment of the body. It consists of a liquid medium - plasma and suspended cell-shaped elements - leukocytes, post-cell structures (red blood cells) and platelets (blood plates). This is the most important body fluid, therefore, questions about blood have always worried people: at what temperature does the blood clot, the composition of the blood and its quality, the necessary amount of it in the body, how to stop bleeding - all this must be known and the knowledge gained, if necessary, be able to put into practice.

at what temperature does blood coagulate

When the blood rages

This process has nothing to do with romantic love experiences. It begins at a body temperature of 44-45 degrees and above, under these conditions, denaturation begins, that is, blood protein coagulates. All of us have seen boiling milk and poached eggs, a similar process takes place here.

Blood boiling point

Boiling is the formation of gas bubbles in a liquid. It is worth remembering that under any circumstances, with a sharp decrease in pressure, the gas dissolved in all liquids condenses into bubbles. Therefore, the pressure drops that are not related to the boiling point of the blood, it is important to remember both those who sink to great depths, and those who rise to a considerable height. In no case should one emerge abruptly - everyone has heard of a caisson disease, the meaning of which is that blood, when it abruptly emerges from the depths, boils with nitrogen bubbles. The phenomenon is not associated with body temperature, it occurs with a rapid rise from depth. In this case, even a fatal outcome is possible, but even without it the consequences for the body will be very serious. All modern diving bots have pressure chambers where they place a sharply floating diver in order to immediately stop boiling blood.

Does the temperature rise?

What does hyperthermia (high temperature) mean for the body? This is a defense mechanism against a pathogenic pathogen. In an emergency, pyrogens are produced that are responsible for raising the temperature. With an increase in body temperature to 39 degrees, the production of interferon and leukocytes increases, at this temperature, the death and deceleration of the vital processes of many infectious pathogens begins.

There are elevated temperatures up to 39 degrees and high, exceeding this indicator. When they talk about the boiling point of blood, they mean the hyperpyretic temperature - over 41 degrees.

At 42.5 degrees, an irreversible metabolic process develops in the brain cells. And at what temperature does blood clot? Upon reaching 45 degrees, the process of protein denaturation of the cells of the whole organism begins, which, unfortunately, leads to death if urgent measures are not taken. Therefore, with an illness, be very careful about the data on the thermometer. The temperature of 40 in a child and an adult is the threshold to which processes can proceed with benefit for the body, activating its protective forces, and hyperpyretic temperature is dangerous for human life.

Blood movement

It is carried out in a closed vascular system, its circulation occurs under the action of the strength of the heart, which is rhythmically reduced. The normal blood volume in the male body is 5.2 liters, in the female - 3.9 liters. For comparison, the blood volume of a newborn is 200-350 ml.

Human blood composition

Now that it’s clear under what circumstances and at what temperature a person’s blood boils, let's examine the composition of the main fluid of our body. The total blood mass is approximately 8% of the total body weight. The composition of the blood is represented by cells, cell fragments and plasma - an aqueous solution. The share of cellular elements - hematocrit - in the total blood volume is about half, or rather, 45 percent.

Blood function

blood donation

The most important fluid in our body serves as a vehicle for it, transporting important substances, thanks to the blood, we maintain the right balance within us called homeostasis. Blood also plays a major role in protecting the body from foreign substances.

In a closed system of blood vessels, blood performs a variety of functions.

  1. Transport, divided into: respiratory (oxygen is transferred from the lungs to all tissues, and carbon dioxide is transferred from tissues to the lungs), nutrient (substances are delivered by blood to tissue cells), excretory (blood removes excess metabolic products), thermoregulatory (regulates body temperature ), regulatory (transfer of hormones (signaling substances formed in organs), blood is a link between various systems and individual organs.
  2. Blood protects our body from foreign bodies.
  3. The function of maintaining the constancy of the internal environment of the body - the balance of acids and alkalis, electrolytes and water.
  4. Mechanical, providing a rush of blood to the organs. It is clear that upon reaching the boiling point of blood all its functions are also reduced to zero.

What carries blood?

These are oxygen and carbon dioxide. With the help of blood, the necessary nutrients are delivered to the liver and other organs after they are absorbed into the intestines.

Thanks to this, the supply of organs is ensured, the metabolism in the tissues takes place, in addition, the decomposition products from metabolic processes are carried out by the kidneys, lungs and liver. Blood also carries hormones throughout the body.

Due to the cells of the immune system and antibodies, the body is protected from foreign molecules. To prevent severe blood loss in the body, a physiological blood coagulation system works.

Blood Properties and Composition

The suspension properties of blood depend on the protein composition of the plasma (with a normal ratio of albumin more than globulins).

Colloidal properties of blood are associated with the presence of proteins in plasma. Since protein molecules can hold water, the properties ensure the constancy of the liquid composition of the blood.

The electrolyte properties determined by the osmotic pressure of the blood depend on the content of anions and cations.

The plasma of a healthy person contains about 8% of proteins, of which the proportion of serum albumin is 4%, serum globulin - 2.8%, fibrinogen - 0.4%. The percentage of mineral salts in plasma is approximately 0.9-0.95%, taken on an empty stomach glucose test normally shows 3.6-5.55 mmol / liter.

What temperature is dangerous for a person is the one at which blood protein coagulates, but the ratio of blood cells and their number are also the most important indicators of human health. As for the hemoglobin content, in men its normal proportion is up to 8.1 mmol / liter, and in women - up to 7.4 mmol / liter. The number of red blood cells in 1 mm³ of blood: in men - 4.5-5 million cells, in women from 4 to 4.5 million. The number of platelets in 1 cubic millimeter of 180-320 thousand cells, white blood cells - 6-9 thousand.

Uniform blood elements (red blood cells, platelets, white blood cells) occupy 46% of its composition, plasma - 54%.

What temperature is dangerous for blood? Liquid blood intended for donation is stored at 4 degrees Celsius for up to three weeks, in such conditions about 70% of the initial number of viable red blood cells is preserved. Three layers can be distinguished in the settled blood: the upper one, formed by a yellowish plasma, the middle, gray, relatively thin, which make up the white blood cells, the lowest is the red blood cell.

Red blood cells

red blood cells due to red blood cells

Blood is red due to red blood cells. They are the most numerous of the shaped elements. In a mature state, the red blood cell does not contain a nucleus. Their life span, when they circulate throughout the body, is 120 days, and then they are destroyed in the liver and spleen. The structure of red blood cells includes an iron-containing protein - hemoglobin, due to which the main function of red blood cells is provided - this is the transport of oxygen and other gases. In the human lungs, hemoglobin binds oxygen, where it turns into a light red substance oxyhemoglobin. Further, passing into the tissues, oxyhemoglobin releases oxygen, hemoglobin is formed, the blood again acquires a more saturated, dark shade. Carbogemoglobin from the tissues into the lungs carries carbon dioxide.

Platelet cells

They are also called blood platelets, and these cells are part of the cytoplasm of huge bone marrow cells, they are limited by the cell membrane. Thanks to the joint work of platelets with blood plasma proteins, blood coagulation is provided when a blood vessel is damaged, this prevents blood loss.

White blood cells

These cells are responsible for the immune system, and they are also called white blood cells. Their feature is that they are able to exit into the tissue beyond the bloodstream. The main function of white blood cells is to protect the body from foreign bodies and compounds. White blood cells take an active part in immune responses, secreting special T cells that can recognize viruses and harmful substances, and cells that fight harmful substances. Normally, there are much less white blood cells in the blood than other elements.

Blood plasma

blood composition

From the point of view of body tissues, plasma is the most important intercellular substance of liquid connective tissue, that is, blood.

Plasma contains a solution of electrolytes, signaling substances, metabolites, nutrients, proteins, trace elements, vitamins. The electrolyte composition of the plasma resembles seawater, which may be evidence of the evolution of life forms from the sea.

Plasma translated from Greek means "something formed, educated." The liquid part of the blood contains water and suspensions - proteins (albumin, globulins and fibrinogen) and other compounds. Almost 90% of the plasma consists of water, 2-3% of inorganic substances, and about 9 percent of organic. The composition of blood plasma includes carbon dioxide and oxygen, enzymes, hormones, mediators and vitamins, that is, biologically active substances.

Take care of blood

Our blood is updated quite often, the hematopoietic organ is the bone marrow, the cells of which are located in the pelvic and tubular bones. A deadly temperature of 45 degrees kills our blood, so it is unacceptable to allow even the slightest occurrence of the possibility of raising the temperature to a similar level. Take care of your body, this is the temple of your soul. And take care of your blood. At a temperature of 40 in a child, immediately call an ambulance, every second is important.
