The Shifting heart is set in 1956 in the working class suburb of Collingwood, Melbourne. The play addresses racism treatment towards immigrants in post war Australia. Refugees were given jobs as labourers. The play is written as a response to the violent death of a polish immigrant, who violently took his own life at Christmas. The play itself is also set on Christmas Eve. An Italian family reaches boiling point, when conflict between neighbours of different cultures, arises. Various points will be made, dialogue between characters, setting and themes.…

The heart is what some determine to be the most important organ in our bodies and one of the biggest contributors. It is one of the major organs that if we did not have, it would not be possible for us to live. The heart is about the size of a fist and is broken down into four chambers, the aorta, superior vena cava, pulmonary artery, and the coronary artery. The four chambers include the right and left atrium and the right and left ventricle. The heart is responsible for supplying oxygen and blood to the entire body. Blood passes through these four chambers and then exits and pumps into the rest of the body. The heart also has three layers of walls…
• Epicardium – Viseral layer of the Serous Pericardium that lines the external heart surface…
Each chamber of the heart is lined by a thin layer of smooth tissue known as the:…
The left ventricle has a much thicker wall than the right ventricle because the left ventricle has to pump blood to the whole body while the right ventricle only has to pump blood to the lungs.…
The heart is surrounded by a small cavity call the pericardial cavity, which is inside a larger cavity, the mediastinum.…
The heart lies in the mediastinum and is surrounded by a doubled layered membrane called the pericardium. The outer most layer of the pericardium is called the fibrous pericardium, which anchors the heart to surrounding structures. The inner layer is called the serous pericardium and is composed of two layers. The outer portion is called the parietal pericardium, the inner portion is called the visceral pericardium (epicardium).…
The heart is located between lungs and it is protected by the rib cage, it is thought to be the same size as a closed fist. The heart is protected a membrane called pericardium, this membrane contains a film of fluid which helps prevent fiction. Each side of the heart consist of an atrium and a ventricle. The right side of the heart carries deoxygenated blood through the veins to the lungs, and the left side of the heart pumps oxygenated blood through the arteries around the body. The heart is separated by a septum. “Each of the four heart chambers has a major blood vessels entering or leaving it. Veins enter the atria, and arteries leave the ventricles” (Strech, Beryl; Whitehouse, Mary;, 2010) The pulmonary circulation is the circulation to and from the lungs. The pulmonary artery carries deoxygenated blood this leaves the right ventricle to go to the lungs and the blood is separated between the two lungs and the pulmonary blood then carries oxygenated blood and then enters the left atrium. The main artery which is located leaving the left ventricle is called the aorta. The main vein which is located entering the right atrium is called the vena cava. The vena cava has two part (branches), these two parts are called the superior vena cava and the inferior vena cava. The superior vena cava returns blood from the neck and brain. The inferior vena cava returns blood from the rest of the body. The blood can only flow one way so there are 2 sets of valves which are between th atrium and the ventricles. These valves are called the right and left…
Figure 23.1 In reference to Figure 23.1, identify #1 - #5. 1 Mid-sternal line 4 5th rib 2 Sternum 5 Fifth intercostal space 3 Diaphragm COVERINGS OF THE HEART 5 What is the name of the covering of the heart? The heart is covered by the pericardium, or pericardial sac. 6 What is the function of the fibrous layer of the pericardium? The fibrous pericardium functions to protect the heart and to anchor the heart inferiorly to the pericardium and superiorly to the heart’s vessels. 7 What is the name of the inner layer of the pericardium? The inner layer of the pericardium is a serous membrane called the parietal layer of the pericardium. 8 What is the name of the serous membrane on the surface of the heart? The surface of the heart called the visceral layer, or epicardium. 9 What forms the pericardial cavity? The two portions of the serous membrane, the visceral and parietal layers form the pericardial cavity. 10 What is the function of the serous membrane? The serous membrane produces and maintains the serous fluid in the pericardial cavity. 4…
With all the terrorism that has been happening around the world, it might remind you of the way the narrator of The Tell-Tale Heart goes insane and makes irrational actions. The short novel The Tell-Tale Heart written by Poe is one of his best works from all the stories that I have read that was written by him.…
In all three parts of the book, Prayer: Finding the Heart’s True Home, Richard Foster addresses seven different types of prayer in each section. The first kind of prayer that Foster addresses in part one is the Simple Prayer. The Simple Prayer is essentially exactly what the name says it is. Foster calls it the most basic and primary form of prayers. He also says that is the most common form of prayer found in the Bible. The Simple Prayer is where we come before the Father with our sins and mess-ups and just talk to Him. Foster summarized the Simple Prayer brilliantly when he said, “In a very real sense we are the focus of Simple Prayer. Our needs, our wants, our concerns dominate our prayer experience.”…
The outer wall of the human heart is composed of three layers. The outer layer is called the epicardium, or visceral pericardium since it is also the inner wall of the pericardium. The middle layer is called the myocardium and is composed of muscle which contracts. The inner layer is called the endocardium and is in contact with the blood that the heart pumps. Also, it merges with the inner lining (endothelium) of blood vessels and covers heart valves…
Cardiac muscle is essentially limited to the heart, though it extends slightly into the nearby blood vessels. It too, is striated, but it differs from skeletal muscle. As far as the features, the cells are much shorter, so they are called myocytes rather than fibers. Cardiac muscle is considered involuntary because it is not usually under conscious control; it contracts even if all nerve connections to it are severed.…
