. Comment on “the anatomical setup of lungs is such that any change in the volume will be reflected in the lungs”.
Answers
Explanation:
In humans, the lungs and heart are situated in the thoracic chamber, which is anatomically an air-tight chamber. Thoracic chamber has a separate pulmonary cavity for housing lungs and a cardiac cavity for housing heart. The thoracic chamber is formed dorsally by the vertebral column, ventrally by the sternum, laterally by the ribs and on the lower side by the dome-shaped diaphragm. The anatomical setup of lungs in a thorax is such that any change in the volume of the thoracic cavity will be reflected in the lung (pulmonary) cavity.
Answer: Thoracic Chamber is anatomically an air tight chamber. This helps us to change the volume of our lungs as we can directly alter it.
Such an air tight condition is provided by the arrangement of vertebral column on the dorsal side (behind), ribs on the lateral sides( left and right sides) and diaphragm on the bottom and sternum on the central side (in-front).
