Through which structure does blood flow from the heart to the lungs in the pulmonary circulation?
Left ventricle
Pulmonary artery
Left atrium
Pulmonary veins
The Correct Answer is B
Choice A reason: The left ventricle pumps oxygenated blood into the aorta and then to the rest of the body, not
directly to the lungs.
Choice B reason: The pulmonary artery is the correct answer because it carries deoxygenated blood from the right
ventricle of the heart to the lungs for oxygenation.
Choice C reason: The left atrium receives oxygenated blood from the lungs through the pulmonary veins, so it is not
involved in sending blood to the lungs.
Choice D reason: The pulmonary veins carry oxygenated blood from the lungs to the left atrium, not from the heart
to the lungs.

examination of the entire colon and rectum and can also facilitate the removal of polyps.
Choice C reason: ERCP is primarily used to diagnose and treat conditions in the liver, gallbladder, bile ducts, and pancreas, not the rectum.
Choice D reason: An upper GI endoscopy, or esophagogastroduodenoscopy (EGD), is used to examine the lining of the upper part of the gastrointestinal tract, which includes the esophagus, stomach, and duodenum, not the rectum.
