Why red blood cells have the function of transporting oxygen

Mainly because of hemoglobin.

Functional and structural properties of hemoglobin: hemoglobin is a protein responsible for carrying oxygen in higher organisms. The concentration can be measured with the average cellular hemoglobin concentration.

Hemoglobin is the protein that gives blood its red color, and it is made up of four chains, two chains and two chains, each with a cyclic heme that contains an iron atom. Oxygen binds to iron atoms and is transported by the bloodstream.

Note: The iron on hemoglobin is bivalent ferrous iron, so it is easily oxidized and easily binds oxygen.

Red blood cells contain hemoglobin, which gives the blood its red color. There is iron in hemoglobin, so people with anemia should eat more iron-rich foods to replenish their blood. Hemoglobin can bind to oxygen in the air, so red blood cells can transport the oxygen inhaled into the alveoli to tissues through hemoglobin, and the carbon dioxide produced by metabolism in the tissues is also transported to the lungs through the alveoli and the oxygen outside the body for gas exchange, and the carbon dioxide is excreted from the body.

Human red blood cells are double-sided, concave round cakes. The edges are thicker and the middle is thinner, like a doughnut, except that there is not a hole in it. This shape maximizes oxygen uptake from the surrounding area.

At the same time it is flexible, which allows it to pass through the capillaries and release oxygen molecules, usually 6 m 8 m in diameter. Due to this special shape and relatively small size, the ratio of surface area to volume is large, allowing oxygen and carbon dioxide to penetrate quickly inside and outside the cell.

If you have studied biology, you must know that the nucleus is one of the most important cellular structures of eukaryotic cells, so do you know why red blood cells in the human body do not have a nucleus? So how do red blood cells without a nucleus efficiently complete the task of transporting oxygen?

Because there is hemoglobin in red blood cells, hemoglobin separates from oxygen where there is little oxygen and binds to oxygen where there is more oxygen.

The structure of red blood cells is different from that of other blood cells, and it is concave on both sides, which is conducive to binding to gas, plus hemoglobin.

Red blood cells contain hemoglobin, contain iron, and bind well to oxygen.

Because red blood cells are rich in hemoglobin. Hemoglobin is an iron-containing protein that is red in color. It is easy to combine with oxygen in places with high oxygen content, and it is easy to separate from oxygen in places with oxygen content. This property of hemoglobin allows red blood cells to transport oxygen.

Red blood cells are rich in hemoglobin Hemoglobin is an iron-containing protein Hemoglobin binds to oxygen where oxygen content is highIn places with low oxygen levels, hemoglobin separates from oxygen.

Red blood cells are rich in hemoglobin. Hemoglobin is red in color and contains iron.

In places with high oxygen levels, the iron in hemoglobin readily binds to oxygen;

In places with low oxygen levels, the iron in hemoglobin is easily separated from oxygen.

This property of hemoglobin allows people to combine with oxygen inhaled into the alveoli when inhaling to transport oxygen to body tissues through blood circulation

And in tissues, oxygen in hemoglobin separates, and carbon dioxide produced by tissue metabolism binds to hemoglobin. When the person exhales, it is transported to the lungs through red blood cells, where it exchanges with oxygen outside the body to expel carbon dioxide from the body.

In this way, red blood cells have the function of transporting oxygen.

Red blood cells, often abbreviated as RBC in conventional laboratory tests, are the most abundant blood cells in the blood, and are also the most important medium for transporting oxygen through the blood in vertebrates, and also have immune functions.

Mammalian mature red blood cells are seedless, which means they have lost their DNA. Red blood cells also do not have mitochondria, they release energy by breaking down glucose. Oxygen is transported, and a portion of carbon dioxide is transported.

Carbon dioxide is dark purple when transporting and bright red when transporting oxygen.

Red blood cells are produced in the bone marrow. After the aging of red blood cells, it is easy to cause blood vessel blockage, so they will automatically return to the deep bone marrow, and white blood cells are responsible for destruction;Or when it passes through the liver, it is broken down into bile by macrophages.

Oxygen is transported into red blood cells by free diffusion.

There are three modes of transmembrane transport of substances: free diffusion, assisted diffusion, and active transport.

Free diffusion refers to the entry and exit of substances into and out of cells through simple diffusion, which is characterized by the fact that no carrier is required and no energy is consumed, such as small molecule substances such as water, carbon dioxide, oxygen, ethanol, benzene, etc.

Assisted transport refers to the diffusion of substances in and out of cells with the help of carrier proteins, which is characterized by the transport of substances from the high-concentration side through the cell membrane to the low-concentration side, which requires a carrier but does not need to consume energy, such as glucose into human red blood cells.

Active transport refers to the selection and absorption of nutrients by the cells according to their needs, which is characterized by the transport of substances selected for absorption from the low-concentration side through the cell membrane to the high-concentration side, which requires carriers and consumes energy, such as various ions, amino acids, glucose (except for entering red blood cells), etc. into various tissue cells.

Can you add, I don't quite understand it.

Oxygen transport by red blood cells is a gas-adapted process that allows oxygen from red blood cells to be transferred from the blood to the cells to meet the needs of the cells. When red blood cells have problems transporting oxygen, it may be due to low levels of oxygen in the blood or too few red blood cells, causing the cells to not get enough oxygen. In addition, the shape of red blood cells may change, affecting their ability to transport oxygen.

The solution to this situation is to first check the oxygen level in the blood, and if the oxygen level is too low, you can increase the oxygen level by inhaling oxygen or taking oxygen supplements in the elderly. In addition, blood transplantation can be done to increase the number of red blood cells to improve their ability to transport oxygen. Personal Tips:

Oxygen transport by red blood cells is an important physiological process, so care should be taken to maintain good blood oxygen levels and maintain a normal number of red foci with ascending cells to ensure that cells can transport oxygen properly.

Red blood cells contain a component called hemoglobin, which binds oxygen molecules to form oxyhemoglobin. When oxyhemoglobin passes through the lungs, it absorbs oxygen from the alveoli to form oxyhemoglobin molecules. The red blood cells then transport oxyhemoglobin to the rest of the body, where oxygen is supplied to the body's tissues for respiration.

In this process, the binding between oxygen molecules and hemoglobin molecules is done through a chemical reaction between oxygen and iron ions (Fe2+). After oxygen is combined with iron ions, oxyhemoglobin molecules are formed, because the concentration of oxygen in the lungs is high, and the concentration in tissue cells is low, so oxyhemoglobin will naturally transport oxygen from the lungs to the tissue cells, and Chan Jianxiao provides sufficient oxygen for the body to carry out metabolic activities.

The principle of oxygen transport of red blood cells refers to the catalytic effect of red blood cells to absorb oxygen molecules from oxygen in the blood through the catalytic action of proteins, and the molecules are converted into hemochromatic buried protein (HB) that transports oxygen to form an HB-O2 complex.

Answer]: A red blood cell lacks mitochondria and its energy mainly comes from glycolysis. The bypass energy base of 2,3-bisphosphoglyceric acid can regulate the oxygen transport function of the collapsed joint, which affects the oxygen pulsation and separation curve.

Red blood cells transport oxygen through the primary haemoglobin, while carbon dioxide is transported in the form of carbonic acid, bicarbonate ions, and bicarbonate of potassium and sodium.

After oxygen enters the alveoli through respiration, it enters the capillaries of the lungs by free diffusion, and then enters the blood in the capillaries to bind to hemoglobin, which is carried by hemoglobin and flows throughout the body, and provides oxygen to tissue cells or other cells.

Carbon dioxide, on the other hand, is emitted by cells such as histiocytes through the cell wall of the tissue, and then through the wall of the capillaries closest to the cell, where it binds to hemoglobin.

Which caroxides are life-threatening when red blood cells encounter them because they lose their ability to transport oxygen?

a.Carbon dioxide.

b.Carbon monoxide.

Correct answer to Pi Mingchang case: b

CO binds to red blood cells much more strongly than oxygen, and the burning chop is not easily separated from red blood cells. As a result, red blood cells cannot combine with oxygen and lose the function of carrying oxygen. This leads to a lack of oxygen in the body, which is the most common form of gas poisoning.

Red blood cells transport oxygen through hemoglobin inside.

Hemoglobin is the main component of red blood cells and carries oxygen. Red blood cells move through the blood, transporting the oxygen carried in hemoglobin to the cells of the body.

Hemoglobin is abbreviated as Hgb or HB. Hemoglobin is a special protein that transports oxygen in red blood cells, is the protein that makes blood red, and is composed of globin and heme, and its globin part is a tetramer composed of two different pairs of globin chains (chain and chain).
