Answer #1

Posteriorly, the apex of the lungs located at 7th cervical vertebrae, and base of the lung corresponds to T12. Almost all lower lobes pointed on the posterior chest. Right middle lobe does not project in the posterior chest. This clinical significance helps to examine the chest posteriorly through inspection, palpitation, percussion, and auscultation.

Inspection: Check for Skin color and condition.

Palpitation: Check for symmetry by placing the thumb at the level of T9 or T10. Palpitate the chest for vibration (tactile fremitus).

Percussion: Percuss in the interspace for the predominates of resonance in the healthy adults.

Auscultate: Auscultate for breath sounds from apices C7 to the bases T10 for bronchial, bronchovesicular, and vesicular sounds.

Background Almost all animal and plant cells require oxygen and give off carbon dioxide. This is called gas exchange and it occurs by passive diffusion. Some animals do all or most of their gas exchange across their skin (for example amphibians) but they have very low metabolisms and use very little oxygen and get rid of very little carbon dioxide. On the other hand humans (and other mammals) have very high metabolic requirements and we can’t rely on gas exchange...
