The Left Ventricle of the Heart The left ventricle is one of the four hollow chambers of the heart. Being the largest chamber, it has an ovular shape and it occupies most of the left lateral and anterior planes of the heart. It also occupies most of the apex of the heart. The walls of the left ventricle are denser and stronger than that of the right ventricle. The thicker walls of the left ventricle support its tremendous workload of pumping blood at great pressure out of the heart. As the left
Prolapse The normal Mitral Valve controls blood flow between the upper (left atrium) and lower chamber (left ventricle) of the left side of the heart. The mitral valve allows blood to flow from the left atrium into the left ventricle, but not flow the other way. With each heartbeat, the atria contract and push blood into the ventricles. The flaps of the mitral and tricuspid valves open to let blood through. Then, the ventricles contract to pump the blood out of the heart. The flaps of the mitral and

does not occur correctly. Understanding the anatomy of fetal circulation and how this anatomy changes during the transitional period is important for understanding many neonatal and pediatric diagnoses. In the fetal circulation, the right and left ventricles work in a parallel circuit. The ductus venosus, foramen ovale, and ductus arteriosus are three cardiovascular structures that are important for maintaining this circulation. The umbilical vein carries relatively well-oxygenated blood from the
right and left atria. On the bottom half of the heart, the chambers are known as the right and left ventricles. The atria work together simultaneously and then the ventricles will work in a synchronized manner. The atria will contract and then the ventricles will in tandem. Although it seems simple enough, the heart is one extraordinary organ that has a mind of its own. It all starts with the sinoatrial (SA) node in the upper right corner
Transposition of the Great Arteries is when the aorta and the pulmonary artery are switched. It is also know as TGA or congenital defect. “Transposition means the displacement of a viscous to a site opposite from that which it normally occupies” said by the Merriam-Webster medical dictionary. TGA is a congenital defect which means it is present at birth. The arteries being switched causes there to be two different blood flows instead of one. The body receives deoxygenated blood and the lungs receive
and oldest natural breed of domestic cat in North America with a distinct appearance with a lion-like ruff and a tail that resembles a raccoon’s and is good at hunting. HCM is when “a primary structural disorder of the myocardium; characterized by left ventricular hypertrophy… no symptoms to sustained palpitations, heart failure and sudden cardiac death” (2013). This is caused by a mutation of P.A31P in the cMyBP-C (myosin binding protein C) gene and these being the first non-human cases “feline
of Love Story.” The man who dated Sarah for a short period of time tells the tale. He calls himself Ron, for Ron could have been him, but he doesn’t want to say who he is for fear of looking cruel. He wants to believe what he did was right when he left her. They both didn’t handle their differences properly. The relationship could have been different if they communicated to each other what the relationship meant to them, if Sarah wasn’t so aggressive, and if Ron could let go of his vanity. All these
The aim of this scenario-based assignment is to discuss the therapeutic intervention in the care of a patient with Congestive Cardiac Failure (CCF). A brief summary of the patient’s medical history will be given while discussing one specific nursing problem in terms of heart rate/ rhythm. Also, an overview of aetiology will be given as well as pathophysiology in order to explain the rationale for treatment and monitoring. Relevant research relating to the literature will be utilised throughout in
systolic (medicine) or diastolic (diastole) • Shape refers the intensity over time • Location There are 4 places on the anterior chest wall to listen for the murmur. * Aortic Region -The 2"d right *Pulmonic Region- The 2"d left *Tricuspid Region- The 5th left *Mitra!Region- The 5th left mid clavicular • Radiation The sound of the murmur radiates • Intensity levels that refers to loudness to the murmur it ranges from 1-6 • Pitch it determines if the murmur is low medium or high • Quality is characteristics
transthoracic echocardiogram, the strategies are limited, restricting new answers. This condition is said to start within the sacromeric proteins, as past studies has called this disorder ‘the disease of the sacromere’ 6. The muscle around the left ventricle is so strong that is does not relax enough after contraction to regenerate blood back into the heart 5. Hypertrophic cardiomyopathy was discovered in approximately 50% of young individuals who died suddenly 5. A recent study observed the genes
Cardiac preload is when the blood that circulates throughout the body returns to the heart. There are two types of cardiac preloads; left ventricular preload and right ventricular preload. During preload the blood fills the heart ventricles during diastole. At the time of the cardiac cycle during diastole the valves between the two atriums and the two ventricles are opened. Diastole is when the heart is relaxed and begins filling (preload). The heart can fill with adequate amounts of blood but
allowing blood to mix which creates dysfunctions within. The Overriding Aorta is that of which the aorta is between the left and ventricles, whereas in a healthy heart, the aorta is attached to the left ventricle. Pulmonary stenosis is where the pulmonary valve is much smaller, causing a lack of blood flow. The Right Ventricular Hypertrophy is where the muscle of the right ventricle is more rampant than it would be in a healthy heart, again causing an anomaly in blood flow.(NIH, 2011). These defects

Bed side USS shows minimal IVC collapsibility and almost full right ventricle means further fluid boluses would be detrimental. Second case is clear that child was in dengue shock due to fluid leakage. But the question arise was usual leaking phase was over and why the patient is still having signs of shock .furthermore fluid
Introduction Horror movies can induce fear in two ways. They can let the suspense of not know give you fear or they can really scare you by play loud sounds and showing frightening scenes (Kudo et al. 2008). Frightening movies can make a person feel nervous or anxious making them feel as if their heart is going to pound right out of there chest. We get startled by the unknown and surprised in films giving us anxiety (Grillona 1999). This study investigates the physiological response of fear that
correct anatomic place (Mayo Clinic Staff). This anomaly affects the right side of the heart – the tricuspid valve is located too deep into the ventricle, causing a smaller and weaker right ventricle. The space above the decreased right ventricle is made up of atrial tissue and this can be referred to as right ventricle dysplasia or an atrialized right ventricle (Reynolds). Typically the tricuspid valve has three freely moving leaflets, but in Ebstein’s anomaly one or two of those leaflets get fused
On Friday, 09/23/2016, at approximately 0830 hours, I, Deputy Stacy Stark #1815 met with the reporting party, James R. Boucher (M/W, DOB: 07/25/1959) at the Jackson County Sheriff’s Office. I requested James R. Boucher to come to the Jackson County Sheriff’s Office to review the Wal-Mart video footage I collected and identify the suspect, James Roy Boucher (M/W, DOB: 03/16/1978) on the video footage. I allowed James R. Boucher to view each transaction recorded from the Wal-Mart store. James
Humans have remarkable hands that no other species acquire. Hands provide humans with the potential to play sports, write, and complete every day activities. The significant difference in human hands is the fact that humans have thumbs. Although hands are essential to humans, hands are also important in Fahrenheit 451 by author Ray Bradbury; he uses hands as a motif. On multiple occasions throughout the novel, Bradbury uses hands as a motif to emphasis his themes and main purpose. The beginning of

consider his defensive play competitive, the referees would often interpret his face-high tackling as violent and dangerous. Away from the football field, I've only known Bradley to lash out once. It was a swift left hook dealt to a local thug who, having no idea that Bradley was left handed, approached him as he sat in the passenger seat of a friend's car and made a couple of disparaging remarks. Bradley beckons him over, winds down the window and wham - knocks the guy out cold. So here's a bit
