What does the hydrostatic pressure produced by blood have to do with the Earth s gravitational field

The greater the acceleration due to gravity, the greater the hydrostatic pressure produced by the blood.

The less the acceleration due to gravity, the less hydrostatic pressure the blood produces.

In junior high school, we learned the formula for the internal pressure of liquids: p gh, and we can get the above conclusion.

The presence of gravity gives the blood static pressure.

Good gravity force makes the vertical water pipe have the same gravitational pressure.

First of all, hydrostatic pressure is generated by the influence of gravity in the blood, so the gravitational field will affect the pressure of the blood on the blood vessel wall, and the increase in gravity will increase the hydrostatic pressure of the blood itself and the pressure on the blood vessel wall will increase.

This is directly related to internal organs.

It can be understood that capillary blood pressure and blood pressure are the pressure of blood on the wall of blood vessels, which is only understood by individuals.

The gravitational field state of the universe is the result of the interaction between the mass distribution of all the matter in the universe and the space of the universe, and the trend of the gravitational field state at a specific point in the universe is the direction and magnitude of the gravity field state of all the matter in the universe at this point.

Gravitational force minus the part of the centripetal force, the gravitational force formula f=gmm r2

Gravitational field: is a product of the interaction between dark energy and stars.

Gravitational field: The extent of space that is affected by the Earth's gravity.

The extent of space that is affected by the Earth's gravity. The study of the earth's gravitational field can be used to deduce the shape of the average earth's ellipsoid in geodesy and establish a national earth network and a national level network. in space science to determine the orbit correction of space vehicles subjected to the Earth's gravitational field; It is used in solid geophysics to study the internal structure of the earth and the distribution of mineral resources.

Due to the irregularity of the distribution of mass in the Earth's interior, the Earth's gravitational field is not a force field that changes according to simple laws. But in general, the Earth is very close to a spinning ellipsoid, so the actual Earth can be regularized and called the normal Earth, and the corresponding gravitational field is called the normal gravitational field.

The irregular part of the Earth's gravitational field is called the anomalous gravitational field. The difference between the gravitational potential and the normal bit at any point in the Earth's gravitational field is called the perturbation potential. The perturbation bits are caused by the difference in the mass distribution and shape of the Earth from the average Earth ellipsoid.

Corresponding to the perturbation bits are gravity anomalies and perturbation gravity.

The magnetic field is a special substance that cannot be seen or touched, the magnetic field is not composed of atoms or molecules, but the magnetic field exists objectively. The magnetic field has the radiative properties of wave particles. There is a magnetic field around the magnet, and the interaction between the magnets is mediated by the magnetic field, so the two magnets can act without contact.

An electric current, a moving charge, a magnet, or a special form of matter that exists in the space around the changing electric field. Since the magnetism of a magnet is the same as the current, the current is the movement of an electric charge, so in a nutshell, the magnetic field is generated by the change of the moving charge or electric field. From the point of view of modern physics, the only ultimate components that can form charges in matter are electrons (with a unit negative charge) and protons (with a unit positive charge) [1], so the negative charge is a point object with excess electrons, and the positive charge is a point object with excess protons.

The real source of the field where the moving charge produces the magnetic field is the magnetic field produced by the moving electrons or moving protons. For example, the magnetic field generated by an electric current is the magnetic field generated by electrons moving in a wire[2].

The pressure exerted by the interstitial fluid on the surrounding tissues.

Interstitial fluid (interstitial fluid) infiltrates a part of the fluid from the capillary artery end into the interstitial space, exchanges substances with tissue cells, and then flows back into the blood or lymph through the capillary vein end or capillary lymphatic vein, this part of the fluid is called interstitial fluid. The vast majority of tissue fluid is gelatinous and does not flow freely, so it does not flow to the low-hanging parts of the body due to gravity; The injection needle is inserted into the interstitial space, and the interstitial fluid cannot be aspirated. However, the diffuse movement of water in the gel and the dissolved in water and various solute molecules is not hindered by the gel, and can still exchange substances with the blood and intracellular fluid.

Interstitial fluid is produced by plasma filtering through the wall of the capillary artery, and at the capillary venous end, most of it is absorbed back into the blood through the wall.

Hydrostatic pressure refers to the pressure generated by the liquid, and the physiological hydrostatic pressure is the pressure generated by the fluid accumulated in a certain part of the body on the surrounding tissues.

Contact: Plasma exudes from the capillaries into interstitial fluid, which enters the capillary lymph.

The tubes become lymphatic fluid, which refluxes into the bloodstream and becomes plasma.

Plasma is a liquid component of blood, more than 90% of which is water, which contains thousands of substances, including proteins, lipids, sugars, various salts, amino acids, vitamins, hormones, antibodies, and various metabolic wastes.

Interstitial fluid is formed by capillary filtration of plasma, in which various ionic components are the same as plasma, and various plasma proteins are also present, but their concentrations are significantly lower than plasma.

When the substances in the interstitial fluid enter the capillary lymphatic vessels, they become lymph, so the composition of lymph is similar to that of interstitial fluid. Compared with plasma, lymph contains significantly more water, and most of the fat absorbed from the intestine passes through the lymph and enters the bloodstream.

As can be seen from the above figure, the relationship between the three is mainly reflected in the exchange of substances between each other, capillaries are distributed in the interstitial space and the capillaries have a certain permeability, under normal circumstances, except for blood cells and macromolecular plasma proteins, other substances can pass through the capillary wall, therefore, the interstitial fluid and plasma can be exchanged in both directions, The function of the capillary lymphatic vessel is to infiltrate into the plasma protein and other substances in the interstitial fluid under abnormal circumstances, and these substances will no longer infiltrate back once they enter the capillary lymphatic vessel, therefore, The exchange of substances between lymph and interstitial fluid is unidirectional. When lymph is formed, it passes through all levels of lymphatic vessels and finally returns to the blood circulation through the common lymphatic ducts, and the exchange between lymph and plasma is also unidirectional.

Plasma is the liquid component of blood that is found in blood vessels and is similar to the composition of interstitial fluid, but the protein content in interstitial fluid is less than that of plasma. Lymph is the liquid component found in the lymphatic vessels. During blood circulation, plasma passes through the capillary wall and enters the intercellular space, forming interstitial fluid.

After exchanging substances with cells, the interstitial fluid can be reabsorbed back into the capillaries, or it can pass through the capillary lymphatic vessels to form lymph. Lymph passes through the lymphatic circulation, passes through the thoracic ducts and right lymphatic vessels, enters the left and right subclavian veins, and returns to the bloodstream. Extracellular fluid is an organic liquid.

Interstitial fluid can flow into lymph and become the living environment of lymphocytes, but lymph can not flow directly into the interstitial fluid, help you summarize: plasma can flow into interstitial fluid, interstitial fluid can also flow into plasma, this is bidirectional For example, interstitial fluid can flow into lymph and become the living environment of lymphocytes, but lymph can not flow directly into interstitial fluid, plasma can flow into interstitial fluid, interstitial fluid can also flow into plasma, this is a two-way interstitial fluid can flow into lymph, but lymph can not flow into interstitial fluid, This is a one-way flow of lymph into the plasma, but the plasma does not flow directly into the lymph, which is also unidirectional.
