A basic review of the heart and lung connection: The heart and lungs are
confined within the chest cavity and share different mechanical functions. When
lung diseases reduce oxygen delivery,
placing dangerous stress
on the right heart and potentially causes right heart failure. The
heart pumps oxygen-poor blood from the right side into the lungs via the
pulmonary artery, where gas exchange occurs in tiny air sacs called alveoli.
Once
reoxygenated, blood returns to the left heart and is pumped to the body.
