Pulmonary hypertension is a type of high blood pressure that affects the arteries in the lungs and the right side of the heart. It occurs when the small blood vessels in the lungs become narrowed or blocked, leading to increased pressure in the pulmonary arteries. This increased pressure can strain the heart and eventually lead to heart failure if left untreated. Symptoms of pulmonary hypertension can include shortness of breath, fatigue, chest pain, and fainting. **

Pulmonary circulation is the part of the circulatory system that is responsible for carrying deoxygenated blood from the heart to the lungs, where it picks up oxygen and releases carbon dioxide. This oxygenated blood is then returned to the heart to be pumped to the rest of the body.

While there is no cure for pulmonary fibrosis, treatments such as medications, oxygen therapy, and lung transplant can help manage symptoms and improve quality of life. **
