The lungs are responsible for oxygenating the blood and removing carbon dioxide from it, so adequate blood flow is crucial for maintaining normal respiratory function. The lungs receive blood from both the pulmonary and bronchial circulations. The pulmonary circulation carries deoxygenated blood from the right ventricle of the heart to the lungs, while the bronchial circulation supplies oxygenated blood to the lung tissue. The majority of pulmonary blood flow occurs through the capillaries that surround the alveoli, where gas exchange takes place. Blood flow through these capillaries is regulated by the pulmonary arterioles, which can constrict or dilate in response to various physiological and pathological stimuli. Several factors can influence pulmonary vascular resistance, which affects blood flow through the lungs. These include the partial pressure of oxygen and carbon dioxide in the alveoli, as well as the release of various vasoactive substances such as nitric oxide and endothelin. Overall, lung perfusion physiology is a complex process that involves the interplay of multiple physiological factors to ensure adequate blood flow and gas exchange in the lungs. #physiologylectures #physiologyvideos #physiology #physiologyusmle #usmlestep1physiology #fmge #fmgevideos #rapidrevisionfmge #fmgejan2023 #mbbslectures #nationalexitexam #nationalexittest #neetpg #usmlepreparation #usmlestep1 #fmge #usmle #drgbhanuprakash #medicalstudents #medicalstudent #medicalcollege #neetpg2023 #usmleprep #lungperfusion #pulmonaryperfusion #physiologyneetpg
