USE OF PHYSICAL FACTORS IN MEDICINE

Аннотация

The development of science and technology, industry and scientific research cannot be imagined without physical factors. Physical factors are widely used, especially in many areas of medicine. This is especially noticeable in diagnostics, treatment, surgical intervention and laboratory studies of various diseases. The movement of blood through the vessels in a living organism is also assessed by physical factors. This article explains the movement of blood through the vessels using some physical factors. Keywords: Doppler, effect, vessel, blood, flow, ultrasound, function, electric current, magnet, frequency, movement. Аннотация.

The functions of organs and tissues of a living organism are assessed by physical factors. For example, the movement, fluidity, viscosity, mechanical properties and other characteristics of blood in vessels are studied by hydrodynamics; the spread of blood through vessels is the section on oscillations and waves; the mechanical work performed by the heart is the mechanical section; the generation of biopotentials is explained in the section on electric fields [3,10]. Modern technologies used for diagnostic purposes make it possible to obtain information about a patient's illness by studying the sounds inside the body. Currently, methods based on the use of electric current, electric field and magnetic field - electrocardiography, phonocardiography, ballistocardiography, rheocardiography and magnetocardiography, magnetobiology and others - expand the capabilities of specialists and facilitate fast and accurate diagnostics. In medicine, electric current, electric fields, magnetic fields and other physical factors are used in physiotherapy for the modern treatment of various diseases. Modern treatment methods widely use ultraviolet and infrared rays, alpha, beta, gamma and other radiation [3,4,10]. 5 Journаl of Аnаlyticаl Synergy аnd Scientific Horizon ISSN: 3060-5261 Impact faktor: 9.9 Volume 1, Issue 3, Series C 2025 Computed tomography, Roentgen-ray computed tomography, magnetic resonance imaging, multispiral computed tomography and other modern unique methods have become widely used in nuclear medicine. Based on all of the above, we can say that blood flow in the vessels is also assessed by physical factors. Blood flow is the movement of blood through the cardiovascular system. Blood is a viscous fluid containing plasma and cells. It consists of leukocytes, erythrocytes, thrombocytes and hyalocytes. The properties of the cell significantly affect the nature of the flow [1,10]. Blood flow velocity is the speed at which blood elements move through the bloodstream per unit of time. In practice, specialists distinguish between linear velocity and volumetric blood flow velocity. Linear blood flow velocity is the distance that a blood particle travels through a vessel in a given time (Fig.1). This is a value that directly depends on the sum of the numbers intersecting at a given point in the vessel. Consequently, the aorta is the narrowest part of the circulatory system and has the highest blood flow velocity, reaching ≈0.6 m/s. The "widest" are the capillaries, since their total area is 500 times larger than the area of the aorta, and the blood flow velocity in them is 0.5 mm/s. This ensures excellent exchange of substances between the capillary wall and tissues [2,9]. So, knowing this, in modern clinical practice there are several methods for determining blood flow velocity, let's consider some of them: Ultrasound method: in this method, a special generator generates ultrasound waves and transmits them to the irradiator. The ultrasound wave passes through the emitter into the blood v
