A Brief Look at the Human Heart

6. What happens to Caleb’s systemic cardiac output as a result of his ventricular septal defect (VSD)? Explain your answer. Caleb’s systemic cardiac output will be decreased. His blood will enter the right ventricle be pumped to the lungs, return to the left ventricle and then be shunted back to the right ventricle. This causes more blood to enter the right ventricle. The extra blood then leaving the right ventricle causes a volume overload to the lungs. Because blood is being shunted back to the right ventricle, there is a lesser volume of oxygenated blood that leaves the heart to supply the rest of the body.

Thesis: In The Shifting Heart, the playwright Richard Beynon conveys ideas and representations of Australian identity through the use of narrative techniques, especially dialogue and characterisation. Each character represents an aspect of Australian society in the 1950 's that Beynon perceives to be true. 1st published in 1960. Set in 1956. NUTSHELL-

In the short story The Intelligent Heart, written by Patricia Foster, she created a piece that actually left her readers with an “uncritical awe” and that left her readers contemplating on her idea much deeper. The purpose of this piece was to attain the concept of what an intelligent heart meant and how it should emerge into writers’ personal essays. However, whether or not personal stories were of interest or enjoyable to read anymore was the issue. Foster raised this issue that other writers may have faced as well and it was how she found it challenging to convey her writing and construct it. She stated, “Perhaps it is passé to write about the struggle between temperaments, the duel of consciousness within a family.” She didn’t want to create a piece

In “The Tell-Tale Heart”, Edgar Allan Poe illustrates how obsession can quickly turn into madness and destroy its victim and those connected to them. The narrator tries to convince us that he is in full control of his thought yet he is experiencing a condition that causes him to be over sensitive. Throughout the story we can see his obsession proving his insanity. The narrator claims that he can be a bit anxious and over emotional, he is not insane. He tries to give proof this through the calmness of his tone as he tells this tale. He then explains how although he has much love for an old man who has always treated him kind, he

Salvador Dali once said “There is only one difference between a madman and me. The madman thinks he is sane. I know I am mad.” The personality of the main character in “The Tell-Tale Heart” is that of a madman even though he is in denial about it. The narrator tries to show this through examples. Poe suggests that the main character is crazy by narrator’s claims of sanity, the narrator’s actions, and the narrator hears things that are not real.

2. The defect in Caleb’s heart allows blood to mix between the two ventricular chambers. Due to this defect would you expect the blood to move from left-to-right ventricle or right-to-left ventricle during systole? Explain your answer based on blood pressure and resistance in the heart and great vessels. It goes left to right during systole. The difference is normally, oxygen-poor (blue) blood returns to the right atrium from the body, travels to the right ventricle, and then is pumped into the lungs where it receives oxygen. Oxygen-rich (red) blood returns to the left atrium from the lungs, passes into the left ventricle, and then is pumped out to the body through the aorta. But when an infant has ventricular septal defect it still allows oxygen-rich (red) blood to pass from the left ventricle, through the opening in the septum, and then mix with oxygen-poor (blue) blood in the right ventricle. (ROCHESTER.EDU) but instead when systole occurs the blood gets mixed because of the septum therefore heart needs to pump harder to ensure that enough blood with oxygen reaches the body.

A ventricular septal defect or VSD is a heart defect. It’s congenital, this means that a baby is born with it. It is an opening or hole in the dividing wall called the Septum, between the two lower chambers of the heart, right and left ventricles. Ventricular septal defects are the most common type of congenital heart defects. A VSD allows oxygen-rich blood to pass from the left ventricle through the opening in the septum. Then it mixes with oxygen-poor blood in the right ventricle. There are different types of ventricular septal defects, the type your child has depends on which part of the wall between the ventricles is involved. Also the size of the opening or hole varies. A ventricular septal defect may occur more often in some families, this is because of gene defects. But most of the time, the cause is unknown. Similarly to ventricular septal defect, an Atrial septal defect is a birth defect of the heart in which there is also a hole in the wall in the septum, but instead of dividing the lower chambers it divides the upper chambers of the heart (atria), here a hole can vary in size and may close on its own or may require surgery as well. An atrial septal defect is one type of congenital heart defect, in which also the baby is born with it.

Atrial Septal Defect affects the cardiovascular system of a person’s heart and affects a person’s life. The understanding of the heart and the process it completes in our bodies. As we look into the difference of what the heart does and the challenges you go through when your heart is not healthy. When we our born we our born with heart murmur’s in which they are supposed to close throughout your growing process. Atrial Septsl Defect is a hole in your heart that should be fixed in order for the person to live longer or a full life.

“The Heart Of A Woman” is a two stanza poem by author Georgia Douglas Johnson. The poem focuses on the subject of the freedom, imprisonment, and time shifts that a woman’s heart goes through. These may seem like contrasting ideas, however in Johnson's poem, it provides a heartfelt subject matter. These ideas show how emotions play in the development of a character, in this case the heart, through the use of only two equal-length stanzas.

In the short story of Tell-Tale Heart, the narrator talks about an insane mad man who speaks to himself. He describes what his intentions to kill an old man who he loves, but allows his emotions to overwhelm him with the thoughts that the old man’s eye in which he identifies as a vulture’s eye is invading his every emotion. He goes on to expose his every move insanely and vividly to murder the old man.

The definition of TOF reads, a type of congenital heart defect. Congenital means that it is present at birth (UMMC, 2013). TOF occurs when there is 4 abnormalities all together. One of the 4 abnormalities is when a massive hole is in the wall of the muscle (septum) that separates the 2 bottom pumping cambers (ventricles) of the heart. The massive hole in the abnormality itself is a VSD. A VSD is known as a Ventricular Septal Defect. Due to the location of the VSD, two more abnormalities develop. One being that there is a vast blood vessel which take the blood to the body (aorta) is pulled toward, and “overrides” the ventricular septum so that it sits over both the left and right ventricles; this is called an overriding aorta (UMMC, 2013). The second abnormality that takes place is that the muscle produces obstruction to the blood flow going out the right across the pulmonary valve. The right ventricular outflow tract obstruction, can be due to obstruction below the valve, at the valve or in the pulmonary arteries as they deliver blood out to the lungs (UMMC, 2013). There is different severities of TOF. The most acute form is known as pulmonary atresia. In patients with pulmonary atresia there is no functional pulmonary valve. The right ventricular outflow obstruction leads to thickening of the

     In Edgar Allan Poe’s short-story, “The Tell-Tale Heart,” the storyteller tries to convince the reader that he is not mad. At the very beginning of the story, he asks, "...why will you say I am mad?" When the storyteller tells his story, it's obvious why. He attempts to tell his story in a calm manner, but occasionally jumps into a frenzied rant. Poe's story demonstrates an inner conflict; the state of madness and emotional break-down that the subconscious can inflict upon one's self.

Atrial Septal Defect(ASD) is a very large problem concerning the heart in its overall function. When the heart, being the core of the cardiovascular system, has issues; it effects the rest of the body as a result. The core of the problem resides in the atrial septum. Normally the heart is divided into four separate chambers. But a person with atrial septal defect has an atrial septum that allows the blood from the left side of the heart back into the right side. This results in increased pulmonary blood flow and diastolic overload of the right ventricle. By having this constant left-to-right shunt, it can alter the pulmonary vascular resistance leading to hypertension or even the reversal of the shunt itself.

6. Automaticity – ability of heart to beat spontaneously and repetitively without external neurohormonal control. The heart is capable of beating outside the body, given proper laboratory conditions. Automaticity is evidently linked to fluid and electrolyte balance rather than to nervous system control.
