Specific cancers (ovarian, lung, pancreatic, or metastasized ones) may increase the levels of substances that aid in blood clotting, as does chemotherapy. If you have been on bed rest for a long time, or are taking a long trip in a car or plane, there’s a higher chance you’ll develop blood clots. There are a variety of risk factors that may increase your risk of developing a pulmonary embolism, such as: According to the Mayo Clinic, you can protect yourself against pulmonary embolisms by preventing clotting in your legs. The condition can be life threatening because the clots block the flow of blood to the lungs, but rapid intervention dramatically decreases one’s risk of mortality. Fat from the marrow of a broken, long bone.Blockages could, however, on occasion be caused by other substances, such as: It’s characterized by being a blockage in one of the pulmonary arteries, and is sometimes called a “lung blood clot.” Pulmonary embolisms are most often caused by blood clots that have traveled from the legs (or other body parts in rare cases) to the lungs. One such condition is called a pulmonary embolism. There are various issues that can arise within our lungs, many of which can be life-threatening conditions. And as the pulmonary arteries branch closer to the alveoli, they turn into the pulmonary capillary network, which is comprised of tiny vessels with thin walls that mirror the alveoli structure and bronchioles. The pulmonary artery carries shuttles deoxygenated blood to miniscule air sacs called alveoli, which permit rapid gas exchange.Īs the pulmonary artery follows our bronchi, it repeatedly branches and becomes smaller. The blood found in our lungs is the substance responsible for facilitating the carbon dioxide and oxygen gas exchange. The lungs themselves are a pair of organs, each shaped like a pyramid and connected to our windpipes by our right and left bronchi, which themselves branch into smaller bronchioles. Our lungs keep us alive by ridding our bodies of carbon dioxide, a waste product we produce, and exchanging it with oxygen found in the air around us oxygen is an essential component of many of our bodily functions.
