What substances are in the blood and what are the substances in the blood

Blood is the fluid that circulates and flows in the blood vessels of the human body, and blood is made up of two parts, one is blood cells and the other is plasma. Blood cells are made up of three types of cells, namely red blood cells, white blood cells and platelets, which have different amounts in the blood and perform different physiological functions. For example, the main function of red blood cells is to transport oxygen and carbon dioxide, the main function of platelets is to stop bleeding, and the function of white blood cells is to maintain the normal immune function of the body.

When the number of platelets, white blood cells, or red blood cells is abnormal, the physiological functions of the human body will change significantly. Plasma is mainly composed of water, various inorganic ions, various proteins and antibodies, water accounts for more than 99% of plasma, including potassium ions, chloride ions, albumin, globulins and various coagulation factors, which are the components of blood.

Human blood is made up of 55-60% plasma and 40-45% blood cells (red blood cells, white blood cells, platelets). Blood cells are mainly red blood cells, which carry oxygen to all parts of the body and send the carbon dioxide produced by metabolism to the lungs and excrete it with exhalation. The second is white blood cells, which can help the human body resist the invasion of bacteria, viruses and other foreign substances, and are the guardians of human health; Then there are platelets.

Question 1: What enzymes are contained in the blood What substances anticoagulase is protein.

Question 2: What are the components in the blood? Components of the blood:

Blood is made up of formed components and plasma. Among them, there are three types of peirot bridge forming fractions (blood cells) that make up 45% of the blood.

1.Red blood cells are the most abundant of the formed components of blood, they are small, round and flat, with thick edges, concave in the middle, without seeds, and their main component is hemoglobin. The main characteristic of hemoglobin is that it is easy to combine with oxygen in places with a lot of oxygen, and it is easy to separate from oxygen in places with less oxygen.

Therefore, its main function is to transport oxygen. Hemoglobin is red, and the degree of combination with oxygen determines its color, arterial blood with more oxygen is bright red, and venous blood with less oxygen is dark red.

2.White blood cells: with a fierce force.

Leukocytes are colorless, nucleated round cells, slightly larger than red blood cells, the normal value of leukocytes is --- per liter of blood there are many types of leukocytes, such as granulosa cells, lymphocytes, etc., they each occupy a certain proportion in the blood, when the disease occurs, it will change, can be used as a reference data for diagnosing diseases.

3.Platelets:

Platelets are small, nucleated bodies whose main function is to promote blood clotting. There are --- platelets per liter of blood, and when the number is reduced to a certain level, it is easy to bleed in **, mucous membranes, internal organs, etc.

Except for the formed components, the other parts of the blood are plasma. Plasma is a liquid component of the blood. Plasma contains many important substances, including proteins, inorganic work (potassium, sodium, calcium, etc.), antibodies, hormones, etc. Among them, moisture accounts for 91%-92%.

Question 3: What are the substances contained in plasma IT industry, real estate, senior technician ,......As long as you are willing to give, anything can be rewarded! Man is alive, money is dead.

Blood is a buffering solution, and there are several buffering systems for the sausage

In plasma: H2CO3—NaHCO3, NAH2PO4-NA2HPO4

HHB—NaHB (plasma protein and its sodium salt).

HA—NAA (organic acids and their sodium salts).

In red blood cells: H2CO3—KhCO3, Kh2PO4—K2HPO4

hhb—khb,ha—ka

Hhbo2—Khbo2 (oxyhemoglobin and other potassium salts).

Among them, H2CO3-HCO3- buffer plays a major role. H2CO3 is mainly found in the blood in the form of CO2 in a dissolved state.

When the metabolic process produces a stronger acid than H2CO3 into the blood, HCO3- combines with H+ to form H2CO3, which is immediately taken to the lungs to be partially dissolved into H2O+CO2 and exhaled out of the body.

On the contrary, when the alkaline substances produced by the metabolic process enter the bloodstream, H2CO3 immediately reacts with OH- to produce H2O and HCO3-, which are regulated by the kidneys and excreted in the urine.

The final product of the oxidative decomposition of nutrients such as sugar, fat and protein in the body is carbon dioxide and water, which are catalyzed by carbonic anhydrase and converted into carbonic acid, so carbonic acid is the most abundant and most important acidic substance produced in the body. The hemoglobin (HHB) and oxyhemoglobin (HHBO2) buffer systems that directly buffer carbonic acid in the blood are the hemoglobin (HHB) and oxyhemoglobin (HHBO2) buffer systems.

The blood also has a buffering effect on non-volatile acids such as lactic acid and pyruvate produced during metabolic processes in the body. These substances are generally not excreted in the alveoli, mainly by the buffering effect of bicarbonate in the plasma, such as the carbonic acid produced by the action of lactic acid, which is converted into carbon dioxide and purified out of the body through the alveolar excretion.

Blood is an opaque red liquid that flows through the heart and blood vessels, and is mainly composed of plasma, blood cells, and platelets. Blood cells are further divided into red blood cells and white blood cells. Blood contains various nutrients, such as inorganic salts, oxygen, metabolites, hormones, enzymes and antibodies, etc., which have the role of nourishing tissues, regulating organ activity and defending against harmful substances.

Physiological and pathological changes in various organs of the human body often cause changes in blood composition, so it is often necessary to diagnose diseases through blood tests after illness.

Blood is made up of four components: plasma, red blood cells, white blood cells, and platelets. Plasma makes up about 55% of blood and is a mixture of water, sugar, fat, protein, potassium and calcium salts.

It also contains many of the chemicals necessary for blood clot formation to stop bleeding. Blood cells and platelets make up the other 45% of blood
