Answer:
subscapular bursa
Explanation:
The subscapularis muscle usually is a large muscle positioned across the frontal area of the shoulder blade. The subscapular bursa is situated just between the subscapularis muscle and the chest wall. When there is an inflammation of this bursa it is called subscapular bursitis.
The human body is mostly made up of water (H2O), and there is one oxygen atom in each molecule of water. Note that, although each water molecule also contains two hydrogen atoms, the atomic mass of hydrogen (about 1) is much smaller than the atomic mass of oxygen (about 16). Because of this, hydrogen contributes less to human body mass than oxygen.
