A pulmonary embolism is a tissue fragment (part of a blood clot, fat, amniotic fluid, part of a tumour or bullet fragment) that became loose in the blood stream and was carried by the blood stream to a different location. A pulmonary embolism is, in most cases, a thromboembolism (part of a blood clot), which is carried from the deep veins of the legs or the pevis. It travels up the blood stream, through the inferior vena cava, into the heart, and subsequently into the pulmonary artery. In the pulmonary artery, it arrests, forming a potentially life threating occlusion.
Cor pulmonale is hypertrophy of the right ventricle due to chronic pulmonary hypertension. The pulmonay hypertension means that the right ventricle has to pump blood with greater force, causing its muscle to hypertrophy (enlarge in size).
Therefore, to summarize, a pulmonary embolism is an obstruction of pulmonary blood flow while cor pulmonale is the morphological change of the right ventricle due to pulmonary hypertension.

What condition is indicated by the structural difference between systemic and pulmonary arteries?
Elatic recoil.
Are there valves in the pulmonary artery or the aorta.?
There are not valves in the pulmonary artery or the aorta. However there are valves between these and the heart. Between the right ventricle and the pulmonary artery there is a valve referred to as the pulmonary semilunar valve. Between the left ventricle and the aorta there is a valve called the aortic semilunar valve.
What is the name of the heart valve that lies between the right ventricle and the pulmonary arteries?
tricuspid valve
What is the valve between the right ventricle and the pulmonary artery?
The pulmonary or pulmonic valve (a semilunar valve) controls blood flow from the right ventricle to the "pulmonary trunk" that branches into the two pulmonary arteries carrying blood to the lungs.
What is the connection between the pulmonary artery and the aorta called?
ductus arteriosus
Has there ever been any relationship between Adult onset Asthma and DVT or Pulmonary Embolism?
no
What is the difference between pulmonary fibrosis and pulmonary sclerosis?
They are essentially the same.
What is the difference between COPD and pulmonary fibrosis?
what is the differencebetween copd and pulmonary fibrosis
What is the difference between pleural effusion and pulmonary embolism?
A pleural effusion is a build up of fluid between the (visceral and parietal) layers which line the lungs and chest cavity. Whereas....... A pulmonary embolus is a sudden blockage in a lung artery caused by a blood clot that travels to the lung from another part of the body. NB: - Pleural effusion = problem in visceral and parietal layers - Pulmonary embolus = problem in lung artery
What is the difference between pulmonary and alveolar ventilation?
nothing
What is the predicted oxygen saturation in moderate pulmonary embolism?
In moderate pulmonary embolism, the predicted oxygen saturation may vary depending on the individual, but it is typically lower than normal levels. Patients may present with oxygen saturation levels below 90%, indicating impaired oxygen exchange in the lungs due to the blockage of blood flow to the lungs. Monitoring oxygen saturation is important in assessing the severity of pulmonary embolism and guiding treatment.
What is the difference between pulmonary system and coronary system?
Coronary or cardio is blood flow. Pulmonary or respiratory is breathing.
What the difference between the pulmonary arteries and other arteries in the body?
they carry deoxygenated blood
What condition is indicated by the structural difference between systemic and pulmonary arteries?
Elatic recoil.
What is the difference between an embolus and embolism?
An embolus is a physical mass (fat, air, blood clot, etc) which can travel to a different location in the arteries. An embolism is when an embolus actually blocks a capillary. A thrombus is a physical mass which remains attached to it's site of origin. A thrombus may detach to become a thrombo-embolus which may then cause an embolism.
What determines in which direction carbon dioxide and oxygen will diffuse in the lungs?
pressure difference between carbon dioxide and oxygen level between pulmonary artery and alveolar space
What is a difference between pulmonary embolism and pneumonia?
Pleurisy, also known as pleuritis, is an inflammation of the pleura, the lining of the pleural cavity surrounding the lungs. Among other things, infections are the most common cause of pleurisy. Pneumonia is a inflammatory condition of the lung. It is often characterized as including inflammation of the parenchyma of the lung (that is, the alveoli ) and abnormal alveolar filling with fluid (consolidation and exudation).
