Example Question #502 : Systems Physiology
The pulmonary veins carry oxygen-rich blood from the __________ to the __________.
lungs . . . left ventricle
right ventricle . . . lungs
lungs . . . left atrium
lungs . . . right atrium
left atrium . . . lungs
lungs . . . left atrium
The pulmonary veins carry oxygenated blood form the lungs to the left atrium of the heart. The pulmonary arteries carry deoxygenated blood from the right ventricle to the lungs.
Example Question #503 : Systems Physiology
What is the name of the blood vessel that carries newly oxygenated blood from the lung back to the heart?
Pulmonary vein
Pulmonary trunk
Superior vena cava
Aorta
Pulmonary artery
Pulmonary vein
When blood needs to leave the heart to become oxygenated, it leaves the right ventricle through the pulmonary trunk, which then splits into the right and left pulmonary arteries. This blood goes to the lungs, becomes oxygenated, and comes back to the heart via the right and left pulmonary veins, which empty into the left atrium. The newly oxygenated blood travels through the left atrium and ventricle of the heart before it exits through the aorta to deliver freshly oxygenated blood to the rest of the body.
Example Question #3 : Help With Pulmonary Circuit Physiology
Which pairing of chambers corresponds to those that receive deoxygenated blood and pump blood into the pulmonary circuit?
Left atrium and right ventricle
Right ventricle and atrium
Left and right ventricle
Left ventricle and right atrium
Left ventricle and atrium
Right ventricle and atrium
The heart has four chambers and only two interact with deoxygenated blood. The right atrium receives deoxygenated blood from the superior and inferior vena cava which then passes through the tricuspid valve into the right ventricle where it is pumped towards the lungs to be oxygenated.
