What is the way oxygen is stored in the blood

Very few dissolve in water and most bind to hemoglobin in red blood cells.

Oxygen is only accounted for, and hemoglobin (Hb) in red blood cells is an effective tool for transporting oxygen.

Oxygen is mainly transported in the blood through oxyhemoglobin, because oxygen can combine with hemoglobin in red blood cells to form oxyhemoglobin, which transports oxygen to the tissues and organs that need it, and then the oxygen is separated from the hemoglobin for the use of tissues and organs. If the concentration of hemoglobin decreases and the body's ability to transport oxygen decreases, a range of symptoms of anemia occur.

Precautions for the transport of oxygen

Factors influencing oxygen transport include blood pH and partial pressure of carbon dioxide, temperature, intraerythrocyte 2,3-bisphosphoglyceric acid, carbon monoxide, and other factors.

A decrease in pH or an increase in the partial pressure of carbon dioxide decreases the affinity of Hb for oxygen molecules, and this effect is called the Bohr effect. When the temperature increases, the affinity of HB for oxygen molecules decreases, carbon monoxide can combine with HB to form carbon monoxide hemoglobin, which occupies the point where HB combines with oxygen molecules, affecting the transport of oxygen in the blood, and carbon monoxide hemoglobin is cherry colored, so people with carbon monoxide poisoning have severe hypoxia in the body, but no cyanosis.

1. The oxygen density is larger than that of air, the mouth of the gas collection cylinder should be placed upwards or on the desktop, and the frosted surface in the ground glass sheet must be in contact with the mouth of the gas collector cylinder, which is conducive to sealing and use, and the frosted glass side is facing down.

2. Oxygen is stored in a sky blue and black cylinder with a working pressure of about 150 kg cm2.

3. Oxygen is an element of oxygen.

Formed as a elemental substance, the chemical formula O2, its chemical properties.

It is relatively reactive and can react with oxygen with most elements. It is not very active at room temperature, and it is not easy to interact with many substances. But under Gao Xuan Wu Wen, it is very lively, and can directly combine with a variety of elements, which is the electronegativity of the oxogenic brother.

Second only to fluorine-related.

It enters the trachea from the nasal cavity or oral cavity, from the trachea to the bronchi, the bronchial segments to the alveoli, enters the capillaries through the alveolar membrane and binds to hemoglobin, and reaches the left ventricle through the pulmonary circulation called arterial blood, which enters the systemic circulation to various aerobic organs and tissues in the body.

Hemoglobin can also be combined with carbon dioxide, carbon monoxide, cyanide ions, and the way of binding is exactly the same as oxygen, the difference is only that the firm process of binding is disturbed early, and once carbon monoxide and cyanide ions are combined with hemoglobin, it is difficult to leave.

This is the principle of gas poisoning and cyanide poisoning, and in this case, other substances that bind to these substances can be used to detoxify, such as carbon monoxide poisoning, which can be treated by intravenous methylene blue.

Blood flows in a circular direction through the heart and vascular system under the action of the heart pump. It includes the systemic circulation and pulmonary circulation, and is connected to each other to form a complete circulatory system.

There are two forms of oxygen transport. First, it is directly soluble in plasma transport, but its amount is very small; The second is the transport of hemoglobin in red blood cells, which is the main form of oxygen transport.

Oxygen combines with ferric iron in hemoglobin to form oxyhemoglobin, which is affected by the partial pressure of oxygen. In places with high partial pressure of oxygen, such as in the lungs, oxyhemoglobin production increases; In the tissues of the hypogeno-depleted state of the hypogen, oxyhemoglobin releases oxygen; It is used by tissue cells, so its amount is gradually reduced.

In arterial blood, about 20 milliliters of oxygen are carried for every 100 milliliters of blood; In venous blood, only 15 milliliters of oxygen are contained for every 100 milliliters of blood, which means that about 5 milliliters of oxygen are released into the tissues for every 100 milliliters of arterial blood during circulation. All factors that affect the oxygen carried by hemoglobin can cause hypoxia.

The process by which hemoglobin combines with oxygen is a very magical process. First of all, an oxygen molecule binds to one of the four subunits of hemoglobin, and the globin structure changes after combining with oxygen, resulting in a change in the white structure of the entire hemoglobin egg ring.

This change makes it easier for the second oxygen molecule to bind to another subunit of hemoglobin than the first, and its binding further facilitates the binding of the third oxygen molecule, and so on until each of the four subunits that make up hemoglobin binds to each of the four oxygen molecules.

There is a red iron-containing protein in the red blood cells called hemoglobin, and the reason why red blood cells are red is because they contain hemoglobin; Hemoglobin is easily bound to oxygen in places with high oxygen content (hemoglobin binds to oxygen molecules to oxyhemoglobin); In places with low oxygen content, it is easy to separate from oxygen; This property of hemoglobin allows red blood cells to transport oxygen, in addition, red blood cells also transport a portion of carbon dioxide Most of the carbon dioxide in the blood is transported through plasma

So the answer is: the hemoglobin in red blood cells is used to transport oxygen
