Question
Chapter 22, Problem 4RQ
Summary Introduction
To determine:
The largest surface in both the lungs.
Introduction:
The lungs are paired sacs that rest in the wall of the thoracic cavity. They are made up of many subsections ranging from the lowermost to the uppermost (base and apex) and the regions covering different cross-sections of the lung. The pair of lungs in the human body provides the site for the gaseous exchange within the human body.

effort?
(a) One can breathe out air totally without oxygen.
(b) One can breathe out air through Eustachian
tube by closing both nose and mouth.
(c) One can consciously breathe in and breathe
out by moving the diaphragm alone, without
moving the ribs at all.
(d) The lungs can be made fully empty by forcefully
breathing out all air from them.
