The Tell Tale Heart ( ANNOTATED )

Product Information

Style and genre: Heart of Darkness is a frame story: the first narrator is the unnamed passenger on board the Nellie on the Thames listening to the primary narrator, Charles Marlow, who is relating the events that happened to him when he was in the Congo. Marlow also reports the words of other characters and the stories they tell, drawing the reader deeper into the narrative frame structure. Infective endocarditis is a bacterial or fungal infection of the heart and can include but is not limited to the cardiac valves. These vegetative growths can be acute or chronic and are dangerous because of the potential embolization risk if they were to fragment. The role of the pacemaker is to coordinate the contraction of the heart muscle, therefore it regulates the heart rate

Blood will then exit the right ventricle through the pulmonary valve and enter the lungs to be oxygenated. The heart is also difficult because the fatty tissue that surrounds the heart can obscure the openings to the vessels. This means that you really must experience the heart with your hands and feel your way to find the openings. Many people will be squeamish about this, and because the heart is slippery, it is easy to drop. Don't be shy with the heart, use your fingers to feel your way through the dissection. With your fingers or probes in the aorta and the pulmonary trunk you should notice that they criss-cross each other, with the pulmonary trunk in the front. c Decide how the hearts are to be disposed of. This should either be by incineration, or in a dustbin or container used for food wastes that are not to be fed to animals.The heart has a somewhat pyramidal form and is enclosed by the pericardium. Its base (roughly square-shaped) points posterior while its apex points to the left and inferiorly 7. It is positioned posteriorly to the body of the sternum with one-third situated on the right and two-thirds on the left of the midline. Its left-sided orientation is formally known as levocardia (cf. dextrocardia). When evaluating the heart for potential CAD, usually a nonenhanced calcium scoring sequence is first performed to assess for coronary artery calcification. This low-dose technique allows for the detection of calcifications of the coronary arteries. Although this technique does not give any information about potential hemodynamically relevant stenoses, an Agatston score can be calculated based on that data. The calculated Agatston score allows for an early risk stratification of patients with a high Agatston score (>160) who have an increased risk for a major adverse cardiac event (MACE) 4. Post-processing If you have access to a magnifying video camera you could project a demonstration dissection. If you have a plastic model heart, a number of students could work from that. Prepare a handout with a drawing of the heart and questions for students who are not taking a practical part in the activity. Students who are unwilling to handle hearts, but keen to see what is going on could take digital photographs of the heart in different stages of dissection. The auricle is the flap that covers the atrium, it looks like an ear. The pulmonary trunk is the located at the front of the heart and enters at an angle.

Right Heart Function: Therefore, the goal of the right side of the heart is to deliver deoxygenated blood from the body to the lungs to become oxygenated. Now this is the point. You fancy me mad. Madmen know nothing. But you should have seen me. You should have seen how wisely I proceeded — with what caution — with what foresight — with what dissimulation I went to work! I was never kinder to the old man than during the whole week before I killed him. And every night, about midnight, I turned the latch of his door and opened it — oh so gently! And then, when I had made an opening sufficient for my head, I put in a dark lantern, all closed, closed, that no light shone out, and then I thrust in my head. Oh, you would have laughed to see how cunningly I thrust it in! I moved it slowly — very, very slowly, so that I might not disturb the old man's sleep. It took me an hour to place my whole head within the opening so far that I could see him as he lay upon his bed. Ha! would a madman have been so wise as this, And then, when my head was well in the room, I undid the lantern cautiously-oh, so cautiously — cautiously (for the hinges creaked) — I undid it just so much that a single thin ray fell upon the vulture eye. And this I did for seven long nights — every night just at midnight — but I found the eye always closed; and so it was impossible to do the work; for it was not the old man who vexed me, but his Evil Eye. And every morning, when the day broke, I went boldly into the chamber, and spoke courageously to him, calling him by name in a hearty tone, and inquiring how he has passed the night. So you see he would have been a very profound old man, indeed, to suspect that every night, just at twelve, I looked in upon him while he slept. The atrioventricular node (AVN) is a group of specialised cells situated in the atrioventricular septum just above the coronary sinus ostium. 1,4,5 See the Labelling the heart activity for additional support in using this interactive. Parts of the heart Blood is composed of plasma, erythrocytes, leucocytes (phagocytes and lymphocytes) and platelets. 6.2.7 State that the following are transported by the blood: nutrients, oxygen, carbon dioxide, hormones, antibodies, urea and heat.Your AV node is located in an area known as the triangle of Koch (located between the septal leaflet of the tricuspid valve, the coronary sinus and the membranous portion of the interatrial septum). This is near the central area of the heart. When a person is at rest, the oxygen demand of their cells is relatively low and so a lower heart rate is maintained TRUE! — nervous — very, very dreadfully nervous I had been and am; but why will you say that I am mad? The disease had sharpened my senses — not destroyed — not dulled them. Above all was the sense of hearing acute. I heard all things in the heaven and in the earth. I heard many things in hell. How, then, am I mad? Harken! and observe how healthily — how calmly I can tell you the whole story. The arteries carry the blood rich in oxygen from the heart to different parts of the body. The pulmonary artery, being an exception, carries deoxygenated blood to the lungs for purification. preoperative assessment of the coronary arteries before noncoronary cardiac surgery if intermediate risk of CAD
