Informative Speech About Heart Surgery

The primary structure of the heart starts with the four chambers, the right atrium, left atrium, the left ventricle and the right ventricle. There is a division in the heart separating the right and left side by the septum, this is so that the oxygenated blood and deoxygenated blood are kept separate. The right side of the heart carries the oxygenated blood and the left side carries the deoxygenated blood. The heart also contains four sets of valves, two sets of semi-luna

Left ventricle pumps the blood into the aorta, where the blood is supplied to the body tissues by the systemic arteries.

The heart is one of the most important organs in the body. The heart is responsible for pumping blood throughout the human body supplying the tissue with oxygen and nutrients and removing carbon dioxide and waste. If the heart does not supply blood and oxygen to the organs and tissues, they will die.

The heart is a very strong muscle that has one major job. The heart’s job is to pump blood throughout the entire body. The heart is made up of 4 chambers, and 4 valves. There is the right and left atrium, and a right and left ventricle. The atriums are the superior chambers, and the ventricles are inferior chambers. The left ventricle is the most important, because that is where the blood travels through to go to the aorta, and eventually the rest of the body (Taylor 2015).

The upper two chambers, atria, carry blood to the heart. The lower two chambers, ventricles, carry blood out of the heart. In the pulmonary circuit, blood flows from the veins to the right atrium to the right ventricle to the pulmonary arteries to the lungs. In the systemic circuit, blood flows from the left atrium to the left ventricle to the aorta to the branching arteries to the capillaries throughout the body. The heart has valves to prevent the backward flow of blood. Atrioventricular valves separate the atria and ventricles. The pulmonary valve and aortic valve separate the ventricles and arteries. A heartbeat is the sound the valves make as they open and

delivers blood to the front side of the heart. Just like the left anterior descending branch, the left circumflex artery is in charge of giving blood to the back of the heart.

We’ve all heard of open heart surgery, but not all of us know exactly what it is, which is why I’m here to explain it. To start it off, heart surgery, according to MedlinePlus, “is any surgery done on the heart muscle, valves, arteries, or the aorta and other large arteries connected to the heart.” However, there is also open heart surgery, which although sounds the same there are quite some differences, for when doing open heart surgery, you’re going to have to be connected to a bypass machine during surgery, for your heart has been stopped because of it. Other than stopping your heart, the bypass machine is able to give you the necessary oxygen that your blood needs, move that blood throughout your whole body, and get rid of carbon dioxide.

The heart contains four chambers, the right atrium, the left atrium, the right ventricle and the left ventricle. The right atrium is located in the upper right corner of the heart, above the right ventricle whereas the left atrium which is positioned in the left side of the heart separated from the right atrium and the left atrium. The atria has a very interesting texture, it has a thin, less muscular wall and is smaller in contrast to the ventricles. The atrium is joined to the veins that transport blood out to the heart and is categorized under the four hollow chambers of the heart. The left ventricle is situated in the bottom left portion of the heart. It lies under the left atrium separated by the mitral valve while the right ventricle is located in the lower right portion of the heart below the right atrium and opposite of the left ventricle. The aorta is the largest artery in the body; it begins at the top of the left ventricle. The right pulmonary artery begins at the base of the heart’s right ventricle. The left pulmonary artery passes horizontally in front of the descending aorta and left bronchus. The heart consists of four types of valves, the tricuspid valve located between the right atrium and the left ventricle, the pulmonary valve situated between the right ventricle and the pulmonary artery, the mitral valve positioned among the left atrium and the left ventricle and finally the aortic valve located between the left ventricle and the

The four valves of the heart are the tricuspid valve, the pulmonic valve, the mitral valve, and the aortic valve. The tricuspid valve is located between the right atrium and the right ventricle. It is responsible for allowing blood to flow from the atrium to the ventricle, preventing backflow of blood into the atrium. The pulmonic valve is located between the pulmonary arteries and the right ventricle and is responsible for allowing blood flow from the heart to the lungs. The mitral valve is found between the left atrium and the left ventricle, which allow blood to flow from the left atrium into the left ventricle preventing backflow of blood back into the left atrium. The aortic valve is found between the aorta and the left ventricle and allows blood to flow to the aorta and throughout the body.

The heart is basically a pump that has to circulate the blood around the body delivering oxygenated blood to our organs and then returning deoxygenated blood to our lungs. There are four chambers in the heart, two atria and two ventricles. There are four main valves, mitral, aortic, tricuspid and pulmonary7b.

The hearts role is to pump oxygenated blood to every cell in the body by having a continuous beat. Throughout time the heart has created mystery, however current technology has solved most of the mystery, there still remains an enchantment and eagerness to learn more.

Today, heart surgery is a fairly common surgical procedure in the United States, though it has dropped in the last several years. Heart surgery is a very important procedure because of the importance of the heart. The heart is responsible for pumping blood to the entire body and providing it with oxygen. Heart disease can have an extremely detrimental effect on the body, and can result in death due to lack of blood circulating.

The heart and three type of blood vessels which are the arteries, veins, and capillaries are components of the cardiovascular system. The artery transfers blood out of the heart. The veins transfers blood toward the heart. Capillaries is the site of exchange with the blood or air sacs. The heart helps pump blood through the entire human body. There are two circulatory routes the pulmonary (deoxygenated) and systemic (oxygenated) circulation. The heart is located in the thoracic cavity. The pericardium is the covering of the heart composed of outside layer fibrous pericardium, inner layer serous pericardium, and visceral layer epicardium. Epicardium the heart wall, contains the visceral layer, myocardium, endocardium. The heart has two sides which are the left and right side. The superior chambers are the atrium blood entering. The inferior chambers are the ventricle blood exiting. On the right side, there is the right atrium and right ventricle and on the left side there is the left atrium and left ventricle. The right side allows the circulation of deoxygenated blood from the body and sends it to the lungs. The left side circulatory blood gets oxygenated blood from the lungs and supplies the body with blood. The two heart valves the atrioventricular valves are position between the atrium and ventricle, and the semilunar valves are placed among a ventricle and a pulmonary trunk.

The heart is a muscular organ about the size of a closed fist that functions as the body’s circulatory pump. It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation before pumping it into the various arteries (which provide oxygen and nutrients to body tissues by transporting the blood throughout the body). The heart is located in the thoracic cavity medial to the lungs and posterior to the sternum.

The heart is the pump that propels the blood around the body providing essential nutrition to cells and tissues.
