The research area of pulmonary artery focuses on understanding the structure, function, and diseases related to the pulmonary artery, which is a blood vessel that carries deoxygenated blood from the heart to the lungs for oxygenation. Research in this area may involve studying the development of pulmonary artery diseases, such as pulmonary hypertension, pulmonary embolism, and congenital heart defects affecting the pulmonary artery. Additionally, researchers may investigate new treatment options, diagnostic tools, and prevention strategies for these conditions to improve patient outcomes and quality of life.
