Pulmonary vein

Obstructive Shock Shock is typically described as blood flow that is inadequate to meet the oxygen concentration for normal functioning of the body tissues. Obstructive shock in this case results from mechanical obstruction of the left ventricle stopping the flow of blood out of the heart. With the limited blood flow, the tissues results in anaerobic metabolism since there is limited supply of oxygen. The anaerobic respiration produces a lot of carbon dioxide together with the inherent…

shiny skin, skin that remains a dimple after being pressed for several seconds, and increased abdominal size. Signs of pulmonary edema are shortness of breath, difficulty breathing, and chest pain. Edema in the legs can happen from long periods of time sitting such as a long flight. Persistent leg pain and swelling could be signs of a potential blood clot in the veins called deep vein thrombosis, or DVT for short. Edema could also be the result of eating too much salty food, premenstrual…

first we need to understand some of the differences in veins and arteries. The arteries in the systemic system, deliver oxygenated blood from the heart, in a high pressure low volume stream to the capillaries found throughout the body. The systemic veins carry the deoxygenated blood from the capillary beds in a low pressure, high volume, valve controlled flow, back to the heart. From there, the heart pumps the deoxygenated blood through pulmonary artery to be taken to the lungs to replenish the…

the right ventricle, the tricuspid valve opens and allows the blood to flow from high to low pressure. The valve then closes to ensure blood only flows in one direction (Tandy 2017). After oxygenation, the blood enters the left atrium via the pulmonary veins and fills it until the pressure inside the atrium is greater than that of the left ventricle. This then causes the mitral valve to open and then close again after the pressure in the ventricle becomes greater. The blood returns to the vena…

5. What are the potential contraindications that can prevent someone from having a cardiac catheterization? What is the contraindication that must be considered in Robert Wilson’s case? Why is this of concern? There are potential contraindications to getting a cardiac catheterization, though the only contraindication is the inability to provide an informed consent. There have been unstable patients how have tolerated this procedure but with high risk patients, the nurse has be cautious of…

Total Hip Replacement Hip arthroplasty is using a prosthesis to replace hip joint is one of the most common surgical procedures today (Walker, 2007). A good surgical team will increase the success rate of the total hip replacement. However, proper nursing interventions during pre-operative and post-operative phase of the surgery is very important for the patient. Nurses spend more time with patients compared to the other health care personnel. Therefore, a good nursing care will better…

Question 1. a) “What serosal cavities have been penetrated by the 1st arrow?” The pleural cavity and pericardial cavity have been penetrated by the 1st arrow as they tend to appear in the thoracic cavity on the left side of the chest. b) “Explain the location, the microscopic characteristics of the serous membrane, and the purpose of the serous membrane.” The serous membrane, the peritoneum is located within cavities of the abdomen and the pelvis. Pleura are found in the thoracic cavity…

The heart wall is composed of three layers of tissues: pericardium, myocardium and endocardium (Wilson, Waugh and Ross, 1996). Label structures of the heart for the diagram. Aorta is the 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…

the capillaries. It’s in the capillaries where the diffusion process takes place to exchange molecules of oxygen and nutrients for carbon dioxide of nearby cells, after leaving the capillaries blood is collected into venules the smallest of veins then into veins of increasing size until it reaches the heart [6]. The right side of the heart receives blood returning from the tissues and pumps it towards the lungs,…

Pulmonary Embolism (PE) is a serious and oftentimes life threatening condition that is sadly easily treatable if caught early. The definition of Pulmonary Embolism is a blockage or thrombi in one of the pulmonary arteries of your lungs (Pulmonary Embolism). Most of these thrombi originate in the veins in your lower extremities; though sometimes the thrombi can come from upper extremity veins, renal, pelvic, or right heart chambers, instead. Once in the pulmonary arteries, large thrombi sometimes…
