B
The chest wall wants to pull out
C

Explanation: 

Detailed explanation-1: -Your diaphragm tightens and flattens, allowing you to suck air into your lungs. To breathe out (exhale), your diaphragm and rib cage muscles relax. This naturally lets the air out of your lungs. To get the oxygen your body needs, you inhale air through your mouth and nose.

Detailed explanation-2: -The lungs contain thousands of thin tubes that end in bunches of tiny air sacs (alveoli). Each one of these sacs is covered in blood vessels that connect to a system of veins and arteries that move blood through the body.

Detailed explanation-3: -Lung compliance participates in the lung-chest wall system by opposing the outward pull of chest wall compliance. The net compliance (lung-chest wall system) allows the lungs to achieve appropriate functional residual capacity, the volume remaining after passive expiration.
