Electrical and electrochemical activities of heart Essay

Heart is the chief organ of bole it bed be defined as The hollow muscular organ its rhythmic downsizing flows snag altogether the way throughout the dust. (Heart galvanising) Natural pace noble is established in humans warmness, this pace master start excogitateing from good atria and means magnetic core ventricle it stimulates their muscles. Sinoarterial leaf node SAN is shew in between upper portion of the bosom, later on stimulate right portion of tenderness it stimulates the left atria and ventricle afterward adrenaline is secreted from nervous mail servicement which step on it up the spark electrical impulses or in supplementary words regulates the electrical impulses.Normal warmness overcome atomic number 18 72 per excellent hardly in case of running, exercising, taking stress mettlesome fever snapper beatniks be emergence be induct Nervous dodging release more adrenaline. other motivating consequence of our article covers is electrocardi ogram that is the beat of inwardness vanquish by exceptional electrode on paper or screen.So at this appoint in this article we leave al wholeness study in detail regulatory activities of lovingness which factors ar involves in rule of sum of m nonp argonily beats and keeps aggregate figure and vigorous, how these factors argon dumbfoundd and how did they achieve their hit this is entirely we atomic number 18 going to study in element to erect our understandings about facts of science. Electrical and electrochemical substance activities of nerve center In human spunk natural pace maker is fix, the function which naturally has been given to pace maker is to regulate the disembodied spirit for perform this responsibility it has to go from very(prenominal) different phases.Pace maker is found in the superior right portion of liveliness that is Right atrium this is the place from w here(predicate) the pace maker gathers the narrow cells termed as Sino arterial node so these cells argon similarly termed as pace maker. As the punk beats it generates the electrical sparks per second gear, the spark which has been generated by specialise cell, the function of these sparks is to stimulate the muscles. First it stimulates the superior bedroom of amount it has to wait unless(prenominal) the atria constrict empty from blood. aft(prenominal) stimulating the upper atria it stimulates the ventricles electrically, in like manner it affects the left atria and ventricle in this period. If we go in depth we will come to see that everything function of lie downence is universe controlled by the nervous system, here nervous system is releasing the adrenaline the adrenaline is computable to increase or speed up the sparks per minute, the normal titty beats are 72 per minute simply incase of fever, excitement, stress or whatever psychical or physical stress nookie speedup the rate of heart beats in ensue breathless condition occur smal l-arm on the other during resting situation it is decreased .Let us talk about the phases or ladder which takes place in the electrical use of heart ,As we let talked before it is generated in the sinoatrial node (SAN) which is located in superior Right chamber of heart this is the view from where these electrical impulses propagated to the artrioventricular node ( AVN ) artrioventricular node is seen between the atria and ventricles. after(prenominal) reaching at (AVN) these electrical impulse are send to the into sectioning tissues right bunch together branch is termed as (RBBB) and left bundle branch is termed is as the (LBBB) there are further more subdivision to there Left bundle branches which are know as fascicles first of all electrical impulses are generated in SAN which primary makes the right and left atria to accord and after couple 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 due to exercise or and physical activity which can produce stressed up condition.When SAN fails to work AVN can takes its position hardly 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 mention by electrocardiogram this is the process by which activities can be registered on paper by special electrode use for this process (Heart Electrical Activity).In human ashes there are many chemicals found every chemical has its own duty pin down by disposition in regulation of heart there are besides few chemicals concern which stimulates the function of heart . Neuro inner(a) secretion system helps heart to maintain its regulation this system is linked with the mind and endocrine system this is t he 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 fondness symbol to and changes the activity of cells as well the diam of blood vessels it can also effect the heart rate and the rate of compressing. ( Heart Failure)Electrochemical activities of heart stimulate the heart beats heart regulation, they comprise very primary(prenominal) role in keep, in the body as everything depends upon the function of hearts because when heart gets electrical stimulation it transport/ pumps the blood to the system a nonher factor which helps in pumping the blood is heart beats which is also generated by stimulation of muscles. amount 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 th e less wherefore normal heart beats could be 35 40 heart beats per minute then blood stream to bodys organ reduces which is dangerous (How heart works)It is a firm believe that lessening in I reduces AP polarization which in result reduces the electrochemical plunk 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 geometrical irregularity and it is like a cosmic string system if wiz thing is affected the entire system will be affected but here we are sescribing only the loss cause by reduction in Ca as Ca is rock-bottom it reduces heart beats and blood transport is reduce 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 expectant 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 observed that many late HF patients who doesnt notice their ailment before gets death because of heart abnormality, DADs, EADs and Refs decreased the amount of Ca in myocytes this decrease amount of Ca in myocytes causes systolic disconnect 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 keep on leaking it may cause to death. Electrical and electrochemical regulation of heart Conclusion aft(prenominal) reading this attention-grabbing topic we can come up with the conclusion that heart is one of the biggest gifts of God given to humans. As nature has assign functions to every character reference of the body similarly nature has given special function to heart which makes heart extremely important organ it take blood to complete b ody farewells. 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 sinoatrial 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 biramous 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 fill 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 locomote 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 electrocardiogram electrocardiogram this is recent and helpful technique to hinder whether the heart is working normally or not in this method heart rhythms are famed on paper or screen by specially assigned electrode. Now a long time artificial pace maker is also cosmos made to control abnormalities of heart. Here in this important topic we also read about that what the overlook of any element present of excess of any element or chemical can do with our heart.Nature 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 decreases contraction rate of heart when the heart start contracting less than it is required entire system of body is realised 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 being effected thats what makes one lazy and the major loss cause by this is the heart failure if it is continuously step-down than a time will come when heart will stop working and one meets his death.After reading this prolong 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 external features such these all things work together in a chain like system if one thing is effected the e ntire system got effected this chain which consist of Electrical impulses electrochemical impulses , heart , factors affecting heart , environment and many more things are snarly this chain system is necessary for healthy life we should take care of our health for out founder tomorrow.
