Human blood flows all the time, where does the power come from?

From the beating of the heart. The heart is equivalent to an engine in the whole human body, and the flow of human blood is more powerful than the beating of the heart, and the beating of the heart provides the power for the flow of blood.

The power of blood flow comes from the heart, and the beating of the heart is to provide power to the blood and let the blood flow.

It must be the heart. The heart is like a pump. He's always moving, he's always transporting blood.

What is the blood force that can flow in the blood vessels?

The reason why blood can flow in the human body: when the heart is compressed hard, it is like a pump, which can squeeze out the blood in the heart, and the blood at this time is a liquid like water, which must flow in a fixed pipe blood vessel, and the blood vessels start from the heart, from thick to thin, from long to short, and gradually become capillaries that are not visible to the naked eye.

Blood vessels are divided into two categories: arterial and venous, and the difference between them is that "clean" blood flows in the arteries, while veins only carry "waste-contained" blood.

When the heart compresses hard, it can squeeze the blood out of the heart, and the blood is "clean" blood rich in oxygen and nutrients, which flows through the arteries to the capillaries in the body, sending oxygen and nutrients in the blood to the cells in the body, providing them with breathing and movement.

Knowledge development. The function of blood includes two parts: blood cell function and plasma function, and has four functions: transportation, regulating human body temperature, defense, regulating human osmotic pressure and acid-base balance.

Summary. Flowing life means eternal change and constant development. Whether it is living things or things in the natural world, they all go through different stages and changes.

Flowing life represents continuous movement and evolution, reflecting the law that everything in the world is constantly changing, reflecting the infinite charm and infinite beauty of nature. Flowing life also reminds us that we should cherish the present, grasp the time, and integrate with the natural world to make progress together.

I'm still a little confused, can you be more detailed?

(1) The heart is like the engine of a machine, and the power for the blood circulation in the human body in the heart and blood vessels comes from the beating of the heart

2) It is capillaries, the number of capillaries is large, widely distributed, the inner diameter of the blood vessels is small, only 8-10 microns, only red blood cells are allowed to pass through a single row, the wall of the tube is very thin, only composed of a layer of epithelial cells; Intraductal blood flow is the slowest These features facilitate the adequate exchange of blood and tissue cells

3) The route of the pulmonary circulation is: right ventricle, pulmonary artery, pulmonary capillaries, pulmonary veins, left atrium, when the blood flows through the pulmonary capillaries, it exchanges gas with the alveoli, and the carbon dioxide in the blood enters the alveoli, and the oxygen in the alveoli enters the blood, so that the blood changes from venous blood with less oxygen to arterial blood with rich oxygen; So if it's a blood vessel that surrounds the alveoli, it's the pulmonary artery, and the venous blood flows inward, and it's the pulmonary vein, and the arterial blood flows inward

4) The three types of blood cells in the blood are red blood cells, white blood cells, and platelets The function of red blood cells is mainly to transport oxygen; White blood cells have a role in defending against disease; Platelets have the effect of stopping bleeding and accelerating blood clotting So when the human body is injured and bleeding, the blood component that has the effect of hemostasis and coagulation is platelets

Veins are blood vessels that carry blood back to the heart from all over the body, and when the veins bleed, the blood is dark red and the blood flow is slow; Capillary hemorrhage, blood slowly oozing out like water droplets, and finger pressure or bandage is applied at the distal end to stop the bleeding

5) The renal artery enters the kidney, and gradually branches to form an affinating arteriole, which is then divided into dozens of capillaries, bends and coils to form a glomeruli, and the glomerular capillary then merges into an outburst arteriole, and the outball arteriole branches into a capillary, which winds around the outside of the renal tubule, and then converges into the renal vein

When blood flows through the glomeruli, in addition to blood cells and macromolecular proteins, other substances such as water, inorganic salts, urea, and glucose will be filtered into the renal sac cavity to form protourine; Therefore, after the blood flows through the glomeruli, the obvious changes in blood composition are the reduction of metabolic wastes such as urea and uric acid

So the answer is: (1) Heart.

2) capillaries; One.

3) veins; Arteries.

4) platelets; Telecentric end.

5) afferent arterioles; out-of-bulb arterioles; Waste products such as urea, uric acid, etc.

The blood flow in the blood vessels comes from the heart for good or bad.

What is the blood force that can flow in the blood vessels?

If we follow this inference, when a person is exercising, the blood flow increases, the kinetic energy increases, and the heavier the person, the slower the blood flow becomes when resting, right? The flow of blood doesn't fall down by gravity, so I don't think it has much to do with it.

The flow of blood is the power of the heart, and the heart is the pumping machine. The activity of the brain controls the heart's beating rate, for example, when you are nervous, it will speed up, and at night when you sleep. Your reasoning is unfounded.

Blood Circulation System The blood circulation system is the channel through which blood flows through the body, which is divided into two parts: the cardiovascular system and the lymphatic system. The lymphatic system is an auxiliary device for the venous system, while the circulatory system is generally referred to as the cardiovascular system. The cardiovascular system is a closed transport system consisting of the heart, arteries, capillaries and veins.

The constant beating of the heart and the power that provides the blood to circulate in it provide various cells of the body with substances for survival, including nutrients and oxygen, and also take away carbon dioxide, the product of cell metabolism. At the same time, many hormones and other information substances can also reach their target organs through blood transportation, so as to coordinate the functions of the whole body, therefore, maintaining the blood circulatory system in good working condition is the condition for the body to survive, and the core of which is to maintain blood pressure at a normal level. The circulatory system of the human body is composed of two parts: the systemic circulation and the pulmonary circulation.

Systemic circulation begins in the left ventricle. Blood beats out of the left ventricle and flows through the aorta and several arterial branches derived from it, sending blood to the corresponding organs. The artery then branches several times, the diameter of the tube gradually narrows, the number of blood vessels gradually increases, and finally reaches the capillaries, where the intercellular fluid is exchanged with the tissue cells.

Oxygen and nutrients in the blood are absorbed by the tissues, and carbon dioxide and other metabolites in the tissues enter the bloodstream, turning arterial blood into venous blood. The veins gradually thicken and decrease in number, until finally all the veins converge into the superior and inferior vena cava, from which blood returns to the left atrium, thus completing the systemic process. Pulmonary circulation begins in the right ventricle.

Venous blood is pulsed out of the right ventricle and travels through the pulmonary artery to the capillary network around the alveoli, where it excretes carbon dioxide, absorbs fresh oxygen, transforms venous blood into arterial blood, and then flows back to the left atrium through the pulmonary veins. Blood from the left atrium re-enters the left ventricle and spreads throughout the body through the general circulation. In this way, the blood is continuously running through the systemic and pulmonary circulation, completing the important task of blood circulation.

Why does blood flow in the human body?

The circulatory system is mainly the process by which our heart contracts and relaxes, transports blood throughout the body, and then retracts it to the heart. Only by figuring out the circulatory system and how the blood circulates can the diseases of chronic and acute heart failure be solved.

Because the heart is beating and pumping blood, blood pressure causes blood to flow to the tissues and back to the heart.

Direct power** at 1Heart contraction 2Respiratory Action Assist (Breathing Pump) 3Auxiliary role of muscle movement.

The fundamental motivation is the chemical energy in the ingested food, which is converted into active chemical energy ATP, which is converted into various power required for blood flow.

The objective condition for non-stop flow is that the circulatory system is unimpeded.

The purpose of mobility is to transport nutrients, metabolic wastes, and information substances to other organs and tissues of the body that cannot be moved.

The contraction of the ventricular muscle pumps blood.

Blood is a liquid like water that must flow through fixed tubes (blood vessels), which start from the heart and grow from thick to thin, from long to short, and gradually become capillaries that are not visible to the naked eye. Blood vessels are divided into two categories: arterial and venous, and the difference between them is that "clean" blood flows in the arteries, while veins only carry "waste-contained" blood. When our heart compresses hard, it acts like a pump to squeeze out the blood in the heart, and the blood at this time is "clean" blood rich in oxygen and nutrients, which flows through the arteries to the capillaries densely packed in the body, sending oxygen and nutrients in the blood to the cells in the body, providing them with breathing and "eating and drinking".

At the same time, the cells send the waste and carbon dioxide excreted into the blood vessels, so that the "clean" blood becomes the "waste-contained" blood, which flows into the veins and blood vessels, and excretes the waste gas from the body through the lungs, kidneys and **, so that the blood becomes clean again and returns to the heart.

The cardiovascular system is a complete closed circulatory conduit, which is centered on the heart and connected to various organs and tissues throughout the body through blood vessels, and blood circulates and flows in it. The heart is a hollow, muscular organ that contracts and relaxes at regular intervals, constantly inhaling and pressing blood out, ensuring that blood flows forward in one direction along the blood vessels. Blood vessels are the tubes that transport blood, including arteries, veins, and capillaries.

Arteries originate from the heart, and after repeated branches, the caliber of blood vessels gradually decreases, the number gradually increases, and finally distributes to all tissues of the body, becoming capillaries. The capillaries are reticulated and the exchange of substances between blood and tissues takes place. The capillaries gradually merge into veins, and the small veins merge into large veins, which finally return to the heart to complete blood circulation.
