Because veins are closer to the skin.
yes
This procedure gathers information such as adequacy of blood supply through the coronary arteries, blood pressures, blood flow throughout chambers of the heart, collection of blood samples, and x rays of the heart's ventricles or arteries.
Pulmonary arteries which is the only artery which carries deoxygenated blood.
Arteries carry oxygenated blood away from the heart.
Yes, but this would be seen in arteries and they do not take blood for donations from arteries.
Arteries are blood vessels taking the blood away from the heart. the heart is a very powerful muscle so blood is ejected out at a high velocity and with high pressure.
Pulmonary arteries and pulmonary veins are two different items. The pulmonary artery takes deoxygenated blood from the heart and into the lungs so that the blood can be oxygenated. The oxygenated blood then returns to the heart, via the pulmonary veins, in order to be pumped into the system circulation.
Blood in the arteries is under extremely high pressure as its taking oxygenated blood from our heart.Veins take low pressure unoxygenated blood back to our heart.
taking blood samples from patients for research purpose without consent
Yes they can. They can detect lots of other illegal drugs by taking urine samples too.
well I was taking a science test and the answer is heart failure
Arteries.
