What does bronchopneumonia involve?

Bronchopneumonia primarily involves inflammation of the smaller bronchial tubes, which contributes to the condition. This specific form of pneumonia affects the bronchi and bronchioles, leading to the production of inflammatory exudates in the air spaces of the lungs. This inflammation can result from various infectious agents, and it typically affects multiple lobes of the lungs, leading to the characteristic symptoms associated with pneumonia.

In understanding bronchopneumonia, it's essential to recognize that while it does involve the alveoli as well, the primary focus is indeed on the inflammation of the smaller bronchial structures that can extend to the surrounding alveoli. Therefore, option B accurately describes a critical aspect of bronchopneumonia.
