Why is there blood, why do people have blood

It may be bleeding during ovulation.

Traditional Chinese medicine believes that blood stasis is outside the blood veins.

Any blood that leaves the meridians cannot be discharged and dissipated in time, but stays in the body, or the blood does not run smoothly, and stasis accumulates in the meridians or viscera tissues and organs. The syndrome caused by internal obstruction of blood stasis is called blood stasis pattern.

The causes of blood stasis include cold condensation, qi stagnation, qi deficiency, trauma, etc.

Main clinical manifestations: pain such as a needle bayonet cut, pain in a fixed place and refusal to press, often worsened at night. If the lump is on the surface of the body, the color is bruised; In the abdomen, it is hard and unmoving, which is also called scarring.

The bleeding is recurrent, purple and dark in color, or the stool is black as tarry. The complexion is dark, the skin nails are wrong, the lips and claws are purple and dark, or the subcutaneous purple spots, or the skin is tiny and the blood veins are like wisps, or the abdomen is exposed with green tendons, or the lower limbs are swollen and painful. Amenorrhea is common in women.

The tongue is purple and dark, or petechiae and petechiae, and the pulse is thin and astringent, in short, it is characterized by pain, purple, stasis, lumps, and astringency.

The blood stasis pattern is characterized by stinging pain, refusal to press, lump, bleeding, purple and dark lips, tongue, claws, nails, and astringent pulse. Blood stasis is stopped, the veins are blocked, the qi is blocked, and if it is not passed, it is painful, so the pain is severe, such as needle bayonet cut, and the part is fixed; refusal to press because the pressure makes the qi more blocked, and the pain increases; At night, the yin qi is strong, the yin blood is stagnant and more painful, the blood stasis is condensed locally, and it becomes a lump after a long time, and the lump is between the skin tissues, and the color is blue-purple; If the lump is inside the abdominal cavity, a hard and tangible lump can be palpated, and it will not move and press on it, which is called scarring. Blood stasis blocks the veins, and the flow of qi and blood is blocked, resulting in blood gushing and bleeding.

Because the blood stasis is not removed in the body, the veins are blocked, or it is the cause of re-bleeding, so the bleeding is characterized by stopping and stopping, repeatedly; Blood stasis and internal resistance, poor flow of qi and blood, and loss of skin nutrition, so the complexion is dark, rough as scale armor, and even the lips and claws are purple and dark. The clinical manifestations are different depending on the location of blood stasis, for example, if stasis obstructs the subcutaneous area, then the subcutaneous ecchymosis is seen; The veins of the stasis muscles are obstructed, and the surface of the ** appears filamentous like wisps; If the liver veins are blocked, the abdominal green tendons are exposed; If the lower limbs are obstructed, the green tendons of the lower leg are bulging, bending, and even curled up into a ball; Blood stasis is obstructed, new blood is not generated, and amenorrhea can be seen in women. The tongue is purple and dark, and the pulse is thin and astringent, which is a common sign of blood stasis.

Blood function: 1 provides energy, blood cells carry oxygen, and then there is sugar in the plasma.

2 is to regulate the body's internal systems, such as insulin lowers blood sugar concentrations, adrenaline boosts, etc.

3. The cleansing effect on the body is to convert harmful substances into urine through the glomeruli.

Zhao Liang....No matter what type of high-cheating animals have blood, this is an evolutionary requirement.

In Western medicine, it is a result of poor blood circulation, in the words of traditional Chinese medicine, it is qi stagnation and blood stasis, which is very related to your own physique, and the effect of Western medicine is relatively poor.

This is the embodiment of qi stagnation and blood stasis, and it is necessary to exercise more to open up the meridians and cure all diseases.

Blood is an opaque red fluid that flows through the heart and blood vessels, and its main components are plasma and blood cells. It belongs to connective tissue, that is, the structural hierarchy in the living system. 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. The amount of blood in the human body is about 7 8 of body weight, if the weight is 60 kg, the blood volume is about 4200 4800 ml. Blood vessel rupture caused by various causes can lead to bleeding, and if the amount of blood loss is small, not more than 10 of the total blood volume, it can be recovered quickly through the body's self-regulation; If the amount of blood loss is large, reaching 20 of the total blood volume, symptoms such as rapid pulse and decreased blood pressure will appear; If 30% or more of the body's blood is lost in a short period of time, it can be life-threatening.

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. Blood is divided into venous and arterial blood.

Arterial blood flows in the arteries of the systemic circulation (macrocirculation) and blood in the pulmonary veins that return from the lungs to the left atrium in the pulmonary circulation (small circulation). Arterial blood contains more oxygen, less carbon dioxide, and is bright red. Venous blood contains more carbon dioxide and is dark red.

Note that the blood in the veins is not venous blood, but the arterial blood is arterial blood, because the pulmonary arteries are venous blood and the pulmonary veins are arterial blood. Seek adoption.

No blood is very serious, at the very least, the blood pressure of the human body is to balance the atmospheric pressure, if there is no blood, the person will be pressed into pieces by the atmosphere, and, if there is no blood, what is used to transport nutrients, and oxygen, in short, no blood will die.

The flow of blood can slow down the aging of the body.

1. Plasma. Plasma is the liquid component of blood, accounting for about 50-60% of the whole blood cellar, in addition to water, plasma also contains various plasma proteins, inorganic salts, glucose, hormones and other substances. Plasma has a variety of functions such as maintaining osmotic pressure, maintaining normal blood pH, defense, and fluid regulation.

2. Blood cells. Hemoparhorax is divided into red blood cells, white blood cells, and platelets. (1) Red blood cells.

Also known as red blood cells, they are the most abundant type of blood cells. The number of red blood cells in a normal adult male is 4.5 million cubic centimeters, with an average of 5 million; Adult women are 3.8 million to 4.6 million cubic centimeters, with an average of 4.2 million. The main function of red blood cells is to transport oxygen and carbon dioxide and buffer changes in blood pH.

Red blood cells contain an important protein called hemoglobin, and the main function of red blood cells is done by hemoglobin. Normal adult men have 12-15 grams of hemoglobin per 100 milliliters of blood and 11-14 grams of women, and hemoglobin is closely related to the number of red blood cells. A lower than normal number of red blood cells or hemoglobin is called anemia.

2) White blood cells. White blood cells are colorless and larger in size than red blood cells. The number of white blood cells in the blood of normal people is 5000-9000 per cubic centimeter when they are at rest, and their physiological changes range are large, such as after eating, inflammation, menstrual period, etc., which can cause changes in the number of white blood cells.

Leukocytes are further divided into granular neutrophils, eosinophils, basophils, granular lymphomacytes, and monocytes. The main functions of white blood cells are to defend against germs, immune, and remove dead tissue. (3) Platelets.

Platelets are seedless, also known as thrombocytes. The platelet content of a normal person is 10-300,000 cubic centimeters, and the number of platelets varies greatly with different functional states. The main functions of platelets include promoting hemostasis and accelerating blood clotting, as well as nutritional and supportive effects.
