4 Steps of Cardiac Conduction

4 Steps of Cardiac Conduction Have you ever wondered what causes your heart to beat? Your heart beats as a result of the generation and conduction of electrical impulses. Cardiac conduction is the rate at which the heart conducts electrical impulses. These impulses cause the heart to contract and then relax. The constant cycle of heart muscle contraction followed by relaxation causes blood to be pumped throughout the body. Cardiac conduction can be influenced by various factors including exercise, temperature, and endocrine system hormones. Step 1: Pacemaker Impulse Generation The first step of cardiac conduction is impulse generation. The sinoatrial (SA) node (also referred to as the pacemaker of the heart) contracts, generating nerve impulses that travel throughout the heart wall. This causes both atria to contract. The SA node is located in the upper wall of the right atrium. It is composed of nodal tissue that has characteristics of both muscle and nervous tissue. Step 2: AV Node Impulse Conduction The atrioventricular (AV) node lies on the right side of the partition that divides the atria, near the bottom of the right atrium. When the impulses from the SA node reach the AV node, they are delayed for about a tenth of a second. This delay allows atria to contract and empty their contents into the ventricles prior to ventricle contraction. Step 3: AV Bundle Impulse Conduction The impulses are then sent down the atrioventricular bundle. This bundle of fibers branches off into two bundles and the impulses are carried down the center of the heart to the left and right ventricles. Step 4: Purkinje Fibers Impulse Conduction At the base of the heart, the atrioventricular bundles start to divide further into Purkinje fibers. When the impulses reach these fibers they trigger the muscle fibers in the ventricles to contract. The right ventricle sends blood to the lungs via the pulmonary artery. The left ventricle pumps blood to the aorta. Cardiac Conduction and the Cardiac Cycle Cardiac conduction is the driving force behind the cardiac cycle. This cycle is the sequence of events that occur when the heart beats. During the diastole phase of the cardiac cycle, the atria and ventricles are relaxed and blood flows into the atria and ventricles. In the systole phase, the ventricles contract sending blood to the rest of the body. Cardiac Conduction System Disorders Disorders of the hearts conduction system can cause problems with the hearts ability to function effectively. These problems are typically the result of a blockage that diminishes the rate of speed at which impulses are conducted. Should this blockage occur in one of the two atrioventricular bundle branches that lead to the ventricles, one ventricle may contract more slowly than the other. Individuals with bundle branch block typically dont experience any symptoms, but this issue can be detected with an electrocardiogram (ECG). A more serious condition, known as heart block, involves the impairment or blockage of electrical signal transmissions between the hearts atria and ventricles. Heart block electrical disorders range from first to third degree and are accompanied by symptoms ranging from light-headedness and dizziness to palpitations and irregular heartbeats.

Sick older people are deeply problematic for contemporary forms of Essay

Sick older people are deeply problematic for contemporary forms of health care organisation. Discuss. (Medical Sociology) - Essay Example wess and clan or family properly introduce an incipient stratification.† (Davis & Moore, 1945: p 242: quoted in Zaidi, 1999: p 29) Age-group is one of the most important factors of social stratification that divides human society into the categories of children, young, middle-aged and elderly. Among these categories the elderly or older people make up a noteworthy proportion of every society and maintain the same significance observed by the young and adult individuals. Researches view ageing as a universal phenomenon that exists in all cultures and societies of the globe. Though old age is assessed and estimated through divergent scales, yet the individuals crossing 60 years of age are stated as old people or senior citizens all over the globe. â€Å"Aging is†, Sijuwade observes, â€Å"judged by different criterion in different societies. The transition to old age is identified with several factors such as chronological age, ill health, retirement, physical/mental dete rioration, and death of spouse. Studies reveal that changes in social role (widowhood, grandparenthood, retirement) and physical health dominate the definition of age identity.† (2009: p 1) Special attention is paid to the cause of elderly in contemporary era and disciplines of gerontological sociology and cultural anthropology have been established, which concentrate upon the study of life, culture and activities of the old people. As ethnography is a branch of cultural anthropology, that discusses human cultural traits in a scientific way, the older people also come in the fold of the study of aged. Political authorities and social welfare organisations aim to strive for the sound health of the population at large. It is the therefore the concerns regarding the falling health and medical problems of the elderly are of great significance for them. Governmental departments introduce new policies and revise them time and again for the welfare of the elderly. These social reforms, related to the

Antigone :: essays papers

Antigone3 Often in plays, there are conflicting issues. This is what creates the storyline, or plot. Usually, each play has an antagonist and a protagonist. A protagonist is the main driving force in the play, whereas the antagonist the force that goes against the protagonist. Deciding who is the protagonist and who is the antagonist are really matters of opinion. In the play, "Antigone" by Sophocles, there are different opinions about who is the protagonist and who is the antagonist. In "Antigone," Creon and Antigone have distinct conflicting values. Creon's regard for the laws of the city causes him to abandon all other beliefs. He feels that all should obey the laws set forth by him, even if other beliefs, moral or religious, state otherwise. Antigone, on the other hand, reveres the beliefs of the gods. She feels that the laws of the gods should be obeyed above all others, especially when in respect to family. Creon has a very strong opinion about the laws of the city and the laws passed by him. His method of enforcing them is very strict. In "Antigone," Creon orders that Polynices, Antigone's brother, will not be buried because of his dishonor towards Thebes. Furthermore, if anyone is caught burying him, they will be killed for disobeying his order. Polynices is being punished because he attacked Thebes and betrayed Creon and the people of Thebes. Creon says "Remember this: our country is our safely. Only when the voyages true on course can we establi sh friendships, truer than blood itself." (Antigone 210-213) Creon's harsh punishment on those who disobey the law makes many fear him and dare not to go against him. One example is Ismene's regard for Creon's laws. She tries to talk her sister out of burying her brother because of what could happen to her if Creon found out that she went against him. Ismene says, "I'm forced, I have no choice-I must obey the ones who stand in power." (Antigone 78-79) Not only do the people of Thebes obey the laws of the city because of their fear but because it is a shame to dishonor the king. To go against the king's claim and dishonor the law is to die a more shameful death than Antigone's mother and father.
