Chapter 38 to 43 from guyton.
Study Scheme:
There are 7 mcqs and only Seq from this topic in proff.
Although lengthy topic but important for theory and viva exam.So ,it should be done according to exam point of view.
Follow following points:
1.First do the repeatedly asked question.
2.understand the basic mechanism of respiration.
3.Highlight important points.
4.Remember the values of pressure ,volume, capacities.
5.Make flow charts.
