Pulmonary artery

The mitral valve (MV) plays a crucial role in cardiac function, controlling blood flow between the left atrium and left ventricle. The components of the valve include an anterior leaflet, a posterior leaflet, tendinous chords, papillary muscles, and a saddle shaped annulus at the atrioventricular junction.[1] Deviation in the morphology of any of these components of the valve may result in comprised mechanical integrity of the valve and abnormal leaflet closure.[1] With studies suggesting that…

Pulmonary embolism What is pulmonary embolism? Pulmonary embolism is the medical term for a blood clot that travels to the pulmonary artery. The condition usually causes the sudden onset of chest pain and difficulty breathing. It can also cause you to cough up blood. Pulmonary embolism is a leading cause of death in the United states. Due to the importance of this condition, it is critical that patients understand its causes, symptoms, and treatment. By the end of this article, you will have…

the blood towards the heart when we move our legs. Deep vein thrombosis and pulmonary embolism are together called venous thromboembolism. “The incidence of VTE is 10% to 20% in general medical patients and up to 80% in critically ill patients” (Hinkle & Cheever, 2014, P. 846). DVT is where a blood clot or thrombus forms in a deep vein and It partially…

the body and the plasma is a liquid in which the other components float in (Next slide). Some common problems that can occur in the Cardiovascular System is an Aneurysm and Varicose Veins. Aneurysms occur when there is a weak spot in the wall of an artery. Varicose veins, is quite common, it is when there are problems with valves and therefore prevent blood from returning back to the heart. This can be shown by the pictures shown on the presentation. (Marieb 8th Edition, 2010) (Next…

helps push the blood to flow throughout the body. It is composed of three layers the pericardium (around or outside of the heart), the myocardium (middle layer of the heart), and the endocardium (the inside of the heart). The blood vessels consist of arteries, capillaries, and veins. They help to transport blood throughout the body and also carry blood away or…

Patient comes into the Emergency Room with a chief complaint of swelling and extreme pain in the left leg. After awaiting triage, the patient is finally seen by the physician. Temperature 96.8˚F, Heart Rate 129 beats per minute, Blood Pressure 102/60, Respiratory Rate 23, SPO2 100% on room air. Upon examination of his left leg, it is undeniably blue in color with significant swelling as compared to the right. Superficial veins are noticeably distended and the leg is cool to the touch. A Duplex…

Introduction: Our modern society is engaged in pursuing a healthy and active lifestyle in order to avoid common health problems such as obesity, high blood pressure, and diabetes mellitus to name a few. Exercise duration, frequency and intensity all are relevant in triggering physiological responses in our bodies. For example, skeletal muscles demand an increase in oxygen and substrates and simultaneously remove carbon dioxide and metabolites (Burton et al., 2004). Furthermore, studies have…

Coronary artery disease (CAD; also more simply referred to as coronary heart disease) is a specific type of atherosclerosis, which is in turn a form of arteriosclerosis (Dulson, Fraser, LeDrew, & Vavitas, 2011). All of these medical conditions entail the same problem, which hinders proper blood flow of oxygenated blood in the arteries: the sclerosis (that is, hardening) of arteries in the circulatory system (Sclerosis [medicine], 2016). Arteriosclerosis is a general term used to describe the…

“long-term force of the blood against your artery walls is high enough that it may eventually cause health problems”, (Mayo clinic, 2015). This disease is found by the amount of blood that the heart is pumping and the flow that the blood has to the arteries. When the heart has to pump more blood to the heart, then the arteries narrow and this can cause…
