Can you tell me what is d difference b/w bronchopneumonia and lobar pneumonia..?

Anatomical site: Brochi are part of conducting system to conduct air to the alveoli which are true exchange site for o2/co2 in the lung. When infection involves interstitium/or alveoli called pneumonia, but when it involves conducting tubes like bronchi, then called bronchitis. When both are involved it is called bronchopneumonia. If pneumonia is in one lobe called lobar pneumonia. Shahzeidi, md.
