Left ventricle

major artery that carries oxygenated blood to the body. Pulmonary veins carry oxygenated blood from the lungs into the heart. Left atrium is one of the left upper chambers that takes oxygenated blood from the lungs and pumps it into the left ventricle which carries it to the body (MedicineNet, 2016). Left ventricle is one of the left lower chambers that takes blood from the left atrium and pumps it through the aorta to the rest of the body (MedicineNet,…

the heart. The two main blood vessels that are associated with coronary circulation are the right coronary artery and the left coronary artery. These two major arteries bifurcate off of the Aorta and encircle the heart ultimately meeting at the coronary sinus. The left main coronary artery which runs across the left side of the heart and passes between the pulmonary trunk and left auricle gives origin to two smaller coronary arteries: the anterior interventricular artery (Also…

to the lungs for oxygenation which can then be pumped into the various arteries. The transported blood therefore transports oxygen, hormones and nutrients to body tissues. The four chambers in the heart are known as the right atrium, left atrium, right ventricle…

1. Based on the information provided, the left atrium and left ventricle are not working properly due to mitral valve not working appropriately. The reason this set of valves was chosen is because in the passage, it stated that the X-Ray show an enlargement in the left atrium and left ventricle. This happen is due to inefficient cycle of blood resulting in abnormal heart sound or heart murmur. Mitral valve of the left side is misshape and less flexible. Mitral valve has a leakage and allows…

cardiovascular system. The heart has four main parts: the left ventricle,the right ventricle, the left atrium, and the right atrium. A wall of muscle called the septum separates them. Oxygen-rich blood from the lungs goes to the left atrium by the pulmonary vein. The left atrium then pumps this blood to the left ventricle. The right atrium collects deoxygenated blood from the body and then pumps this deoxygenated blood to the right ventricle. The left vertical…

the rate and rhythm of the heartbeat. The atrioventricular node slows the electrical signal before it enters the ventricles. It is located in the center of the heart between the atria and the ventricles. What the slowing down of the electrical impulses does is to give the atria time to contract before the ventricles do. Impulses are then sent to the muscular walls of the ventricles be a pathway of fibre known as the His-Purkinje…

Every minute, the heart pumps about 1.5 gallons of blood through the body. The heart is “just above the diaphragm, between the right and left lungs” (Balaban 197). About two-thirds of the heart are located on the left side of the chest, while only about one-third of the heart is located on the right side of the ribcage. The cardiovascular system provides a transport system between the heart and lungs. The heart’s most important function is to indulge indispensable nutrients to the tissues and to…

Explain the significance of the thickness of the left ventricular wall. The right ventricle wall is small and thin containing deoxygenated blood. The left is just the opposite. The left ventricle is larger and thicker making it stronger than the right, but containing oxygenated blood. However, since it is pumping blood all around the body, it is at a more forceful rate (Oxford Journals, 2016). The major coronary vessels are on the surface of the heart. What is the advantage of that location?…

the heart muscle has become too stiff. This process mainly relates to the heart muscles of the ventricle chambers. The ventricles are the main problem within heart failure, they are either too stiff or not contracting properly. The heart ventricles cannot pump hard enough during systole, which is called systolic heart failure. Diastolic heart failure is when not enough blood fills into the ventricles during…

Once filled, the right atrium contracts and pumps its contents into the right ventricle through the tricuspid valve. Once the right atrium is drained completely, the tricuspid valve will close to prevent blood from flowing back into the right atrium. Next, the right ventricle contracts, causing the pulmonary valve to open and forcing blood into the pulmonary artery. Once the blood is emptied, the pulmonary valve will close to…
