Mean pulmonary vein diameters at the ostia were variable: right superior, 11.4-12.4 mm; left superior, 9.6-10.5 mm; right inferior, 12.3-13.1 mm; and left inferior, 9.0-9.9 mm. Diameter and cross-sectional area of the left superior pulmonary vein were significantly larger in men than in women (P < .005). As expected, the caliber of three of the four veins gradually increased as they approached the left atrium. Caliber of the left inferior pulmonary veindecreased as it entered the left atrium. None of the veins were round; all were ovoid. Left-sided veins andvenous ostia were less round than right-sided veins (P < .001). CONCLUSION: Pulmonary veindiameter, cross-sectional area, and shape vary. Particular care must be taken when the left inferior pulmonary vein is evaluated for stenosis, as it normally narrows as it enters the left atrium.

What carries bood to the heart and away from the body?
Veins carry blood back to the heart while arterys carry blood away into the body
What is difference between arteies vein?
arteries are thicker then veins
What is the major difference between arteries and veins?
Arteries carry blood away from the heart. Veins return blood to the heart.
Which of the following is a difference between arteries and veins?
artery walls have more elastic tissue and smooth muscle than veins,
What is difference between capillaries and veins?
Capillaries are smaller, thinner and have less surface area than veins. Veins take blood to the heart, and capillaries are the thin tubes that connect the veins and arteries together.
What is the difference between the blood in the arteries and the blood in the veins?
Veins do not pulsate Arteries pulsate Veins can easily collapse Arteries do not collapse (except in shock) Veins contain valves Blood pressure is low in the veins and higher in the arteries
What carries blood to different parts of the body?
Blood vessels such as arterys,capalires,veins
What describes the main difference between veins and arteries in the circulatory system?
