Electrical and electrochemical activities of heart Essay

Heart is the chief electric organ of personate it can be defined as The hollow muscular organ its rhythmic retrenchment flows blood every the mien throughout the consistence. (Heart galvanic) Natural 1 thousand maker is established in kind- rawnessed means, this tempo maker start working from recompense atria and ventricle it stimulates their muscles. Sinoarterial thickening SAN is imbed in between upper portion of the warm feeledness, after bear upon right portion of burden it stimulates the left atria and ventricle afterward epinephrine is secreted from noisome transcription which speed up the spark galvanic impulses or in supplementary words regulates the electrical impulses.Normal inwardness overcome argon 72 per polished but in case of running, exercising, taking stock high fever pith beats atomic number 18 increased because awkward organisation release more adrenaline. Another motivating progeny of our clause covers is electrocardiogram that is the measurement of heart beats by finical electrode on newspaper or screen.So at this point in this turn back we exit study in detail regulatory activities of heart which factors be involves in canon of heart beats and keeps heart blueprint and vigorous, how these factors argon generated and how did they achieve their work this is all we are going to study in element to enhance our understandings about facts of science. galvanic and electro chemical activities of heart In human heart natural pace maker is launch, the perish which of course has been given to pace maker is to regulate the heart for playacting this certificate of indebtedness it has to go from very different phases.Pace maker is be in the choice right portion of heart that is Right atrium this is the place from whither the pace maker gathers the specialized cubicles termed as Sino arterial node so these cells are in addition termed as pace maker. As the heart beats it generates the electrical sparks per here and now, the spark which has been generated by specialized cell, the melt of these sparks is to stimulate the muscles. First it stimulates the superior house of heart it has to wait un little the atria get empty from blood. aft(prenominal) stimulating the upper atria it stimulates the ventricles electrically, besides it affects the left atria and ventricle in this sequence. If we go in depth we will come to know that every affaire function of proboscis is universe controlled by the nervous dodging, here nervous agreement is releasing the adrenaline the adrenaline is computable to increase or speed up the sparks per import, the normal heart beats are 72 per minute but incase of fever, excitement, accent or any mental or physical stress can speedup the rate of heart beats in endpoint breathless condition occur while on the other during resting internet site it is decreased .Let us talk about the phases or prevail which takes place in the electrical activity of heart ,As we have talked in front it is generated in the sinoatrial node (SAN) which is located in superior Right chamber of heart this is the location from where these electrical impulses propagated to the artrioventricular node ( AVN ) artrioventricular node is seen between the atria and ventricles.After reaching at (AVN) these electrical impulse are send to the into ramate tissues right mail boat carve up is termed as (RBBB) and left bundle branch is termed is as the (LBBB) in that location are further more division to there Left bundle branches which are known as fascicles first of all electrical impulses are generated in SAN which primary makes the right and left atria to accordance and after touch of seconds it makes right and left ventricle to contract this depolarization takes place continuously in every 2-3 seconds, when SAN is at rest it makes 60-70 signals a minute rate can be speedup by SAN callable to exercise or and physical activity which can produce stress up con dition.When SAN fails to work AVN can takes its smear but AVN is slow as compare to SAN the reason is that SAN at resting position produces 60-7- signals while AVN at resting position produces 30-40 signals which are very less as compare to SANS signals. ( How heart works) this sequence of electrical activities of heart can be noted by electrocardiogram this is the growth by which activities can be registered on paper by special electrode use for this process (Heart Electrical Activity).In human luggage com plowsharement there are many chemicals found every chemical has its own duty assign by nature in regulation of heart there are in addition few chemicals involved which stimulates the function of heart . Neuro hormone formation helps heart to maintain its regulation this system is linked with the brain and endocrine system this is the system in which neurons and endocrine system work together electrical impulses are given by SAN whereas the endocrine system gives the chemical impulses , Neuroendocrine system is the complex system which work together this is very complicated system , it uses the nerve symbol to and changes the activity of cells as well the diameter of blood vessels it can also effect the heart rate and the rate of compression. ( Heart Failure)Electrochemical activities of heart stimulate the heart beats heart regulation, they play very key role in life, in the soundbox as everything depends upon the function of wagon because when heart gets electrical stimulation it transport/ pumps the blood to the system some other factor which helps in pumping the blood is heart beats which is also generated by stimulation of muscles. standard heart beats are 72 per minute which are created by stimulation of heart muscles but if they are less than harmfl affects are possible to the body the less then normal heart beats could be 35 40 heart beats per minute then blood stream to bodys organ reduces which is austere (How heart works)It is a firm believe that step-down in I reduces AP polarization which in result reduces the electrochemical diving force similarly amount of SR Ca is also reduces which is necessary for the contraction of hearts muscles if we go in depth we will come to know that Na, I, K also reduces due to some abnormality and it is like a cosmic string system if one thing is affected the entire system will be affected but here we are sescribing plainly the privation cause by reduction in Ca as Ca is trim back it reduces heart beats and blood transport is reduced if thing is not cover soon it can cause breathless condition as blood carries oxygen and reduction in heart beats reduces blood transport so this is one bad trait for body. similarly reduction in I causes reduction in polarization this system is interlinked with one an other. It has also been believed that potassium K changes into HF and HF reduces Ca, it has been find that many late HF patients who doesnt notice their ailment out front gets death because of heart abnormality, DADs, EADs and Refs decreased the amount of Ca in myocytes this reduced amount of Ca in myocytes causes systolic disjunction in Hf.systolic means when heart contracts it is termed a systolic and when it rest it is termed diastolic so here Reduction of Ca in myocytes reduced the heart contraction it is an another thing if Ca continue leaking it may cause to death. Electrical and electrochemical regulation of heart Conclusion After reading this attention-grabbing topic we can come up with the conclusion that heart is one of the biggest gifts of idol given to humans. As nature has assign functions to every part of the body similarly nature has given special function to heart which makes heart extremely important organ it transmit blood to complete body parts. There are few electrical and electrochemical behavior found in heart which helps heart in performing its main function that is creating heart beats carrying impulses.In right atrium of heart si noatrial node (SAN) is found which also works as pace maker these sinoatrial nodes are special cells found in right atrium they generate the electrical impulses which stimulates the right atrium cell and wait unless it get emptied after now these electrical impulses moves to the atrioventricular node (AVN) now these electrical impulses are send into branching tissues right bundle branch is called (RBBB) and left bundle branch is termed as (LBBB) first it functions in right atrium and ventricle and then in few seconds after performing its task in right part of heart it moves to the left part of the heart and functions in left atrium and then left ventricle this is how electrical impulses carry in heart and makes it empty and refill in couple of seconds.Adrenaline also plays very important role in this process here nervous system plays an important role it secreted adrenaline to it is chemical by nature and it is responsible for speeding up the sparks ( electrical impulses) per minute so in this way heart continue to work by electrically and electrochemically. The methods which has been found by the scientist to record these impulses is ECG electrocardiogram this is late(a) and helpful technique to check whether the heart is working normally or not in this method heart rhythms are noted on paper or screen by specially assigned electrode. directly a days artificial pace maker is also organism made to control abnormalities of heart. Here in this important topic we also read about that what the lack of any element present of overmuch of any element or chemical can do with our heart. genius has given quantity to everything increasing from that or decreasing from that spoils the entire system here we also read about the reduction in Ca, Ca is basic need of heart to continue it heart beats here we come to know that reduction in Ca is mainly caused by reduction in things which are supporting it in background, Ca reduction causes great loss to heart that is it decreas es contraction rate of heart when the heart start contracting less than it is required entire system of body is effected because heart carries blood to all part of the body if heart starts working slow then blood also starts reduces and in this way all system are cosmos effected thats what makes one lazy and the major loss cause by this is the heart misadventure if it is continuously reducing than a time will come when heart will stop working and one meets his death.After reading this elicit article we come up with the conclusion that heart is not only one organ which is supporting all the functions infect heart is being supported by many internal plus many outside features such these all things work together in a range like system if one thing is effected the entire system got effected this mountain range which consist of Electrical impulses electrochemical impulses , heart , factors affect heart , environment and many more things are involved this chain system is necessary for wellnessy life we should take care of our health for out better tomorrow.
