How do we determine the number of days for a given month in python. Use calendar.monthrange: >>> from calendar import monthrange >>> monthrange(2011, 2) (1, 28) Just to be clear, monthrange supports leap years as well: >>> from calendar import monthrange >>> monthrange(2012, 2) (2, 29)
The Vena Cava is the vein the carries the blood from the body back to the heart. The Aorta is the artery that carries the blood out of the heart into the body. More blood fits â¦ in the entire body than in the heart alone. The Vena Cava carrys de oxygenated blood that is returning from the body and into the right atruim of the heart and the Aorta is the largest artery of the body which tr â¦ ansports oxygenated blood to the rest of the body.     Hope this helps.
Only veins have valves. Arteries have a smaller lume. An artery carries blood away from the heart, while veins transport blood to the heart. The difference is that an artery brings blood to the body and a vein takes blood to the lungs.Arteries and Veins are part of the circulatory system, where arteries carry the blood from the heart to the organs, and the veins carry it from the organs to the heart again.hen the arteries deposit the oxygen and other nutrients through the capillaries, the blood then moves to the veins, which will carry the blood back to the heart. The veins are made from all the capillary branches moving back to gether.
