2. Aim of the lesson:

• to study etiology, pathogenesis &
pathological anatomy of organs of
respiratory system, to learn to differ them
by morphological picture, to study clinicomorphological variants of acute pulmonary
diseases, peculiarities in children,
complications, causes of death.

3. The objectives :

• Student must know :
• morphological characteristics of acute and
chronic inflammatory pulmonary diseases,
CОLD, pleuritis;
• age features of pneumonia;
• Student must be able :
• to interpret macro- & microscopic changes
of pulmonary diseases.
