Thermoregulation: Function, Tasks, Role & Diseases

With thermoregulation, the human body maintains an ambient body temperature of 37 degrees Celsius. Metabolism, as well as muscles and oxygen transport, depend on this temperature. Thermoregulatory disorders present themselves, for example, in heat stroke. What is thermoregulation? With thermoregulation, the human body maintains a body temperature of 37 degrees Celsius, independent of the environment. … Thermoregulation: Function, Tasks, Role & Diseases

Noisy Classes, Bad Students, Sick Teachers

School classes are noisy. This may be because there are about thirty children there – and not all of them are model students. But most of all, it’s because of the poor acoustics in classrooms. High, relatively bare rooms without carpet have long reverberation times: Spoken language is difficult to understand and the many background … Noisy Classes, Bad Students, Sick Teachers

Function of the heart

Synonyms Heart sounds, heart signs, heart rate, medical: Cor Introduction The heart ensures the blood circulation of the whole body through constant contraction and relaxation, so that all Oragne is supplied with oxygen and nutrients and decomposition products are removed. The pumping action of the heart takes place in several phases. Heart action In order … Function of the heart

Excitation formation and conduction system | Function of the heart

Excitation formation and conduction system The work of the heart/function of the heart is triggered and controlled by electrical impulses.This means that the impulses are created somewhere and are passed on. These two functions are performed by the excitation and conduction system. The sinus node (Nodus sinuatrialis) is the origin of the electrical impulses. It … Excitation formation and conduction system | Function of the heart

Sinus node | Function of the heart

Sinus node The sinus node, rarely also called Keith-Flack node, consists of specialized heart muscle cells and is responsible for the contraction of the heart by transmitting electrical potentials, and is thus the clock of the heartbeat. The sinus node is located in the right atrium just below the orifice of the right vena cava. … Sinus node | Function of the heart

Control of the heart action | Function of the heart

Control of the heart action This whole process works automatically – but without a connection to the nervous system of the body, the heart has hardly any possibilities to adapt to the changing requirements (= changing oxygen demand) of the whole organism. This adaptation is mediated via the heart nerves from the central nervous system … Control of the heart action | Function of the heart

Heart Rate Calculation | Function of the heart

Heart Rate Calculation If you want to train in your individual optimal heart rate zone you should be able to calculate your optimal heart rate. The calculation is done according to the so-called Karvonen formula, where the resting heart rate is subtracted from the maximum heart rate, the result is multiplied by 0.6 (or 0.75 … Heart Rate Calculation | Function of the heart

Heart rate during sports

During training or when doing sports in general, you should take care not to overload your body and this is exactly where the heart rate can help you. Besides controlling your heart … Heart rate during sports

MHF | Heart rate during sports

MHF The maximum heart rate (MHF) is different for each person and has nothing to do with individual performance. However, the heart rate plays an important role in training planning and control. The optimal heart rate for training can be determined by formulas or a field test. To determine the MHF yourself, you should be … MHF | Heart rate during sports

Cooperation of heart rate and cardiovascular system | Heart rate during sports

Cooperation of heart rate and cardiovascular system Heart rate and cardiovascular system are closely related. The cardiovascular system performs vital tasks, transports oxygen and nutrients and regulates the supply of heat. The heart is the motor of the human body and, via the vascular system, ensures that, for example, the muscle cells always receive sufficient … Cooperation of heart rate and cardiovascular system | Heart rate during sports

Heart Rate Monitor: Applications & Health Benefits

A heart rate monitor is called a pulse watch. It is able to measure the number of beats that the heart gives off per minute. What is a heart rate monitor? For the most part, heart rate monitors are used by professional and recreational athletes. They are used to increase the quality of training. Pulse … Heart Rate Monitor: Applications & Health Benefits
