rule out foreign bodies
demonstrate excursion or movement of the diaphragm

male
What is wrong with this image?
Done erect
Air fluid levels present
What is wrong with this
Person has the heart on the wrong side
Situs Inversus
Describe the flow of the heart:
deoxygenated blood enters the heart by way of the superior vena cava and inferior vena cava, the right atrium pumps forcing the blood into the tricuspid valve into the right ventricle, the right ventricle pumps and pushes the blood through the pulmonary valve which is headed towards the lungs, at the lungs you breathe in and out to get the deoxygenated blood to the oxygenated blood, the cells in the lungs by the four pulmonary veins, the veins take the blood through the mitral (bicuspid valve)
The pulmonary artery is the only artery that takes deoxygenated blood
Viens take blood toward the heart
Arterys take blood away from the heart
