oxygenated blood from the left atrium is sent, relatively pure, into the carotid arteries taking blood to the head (and brain); ...
De-oxygenated blood enters the right atrium of the heart and flows into the right ventricle where it is pumped through the pulmonary arteries to the lungs. Pulmonary veins return the now oxygen-rich blood to the heart, where it enters the left atrium before flowing into the left ventricle.
Carry oxygenated blood to lungs

In the other vertebrates, the oxygenated blood flows back to the heart to be pumped to the entire body (systemic circulation).
The aorta is the main trunk of a series of vessels which convey the ~ to the tissues of the body for their nutrition. It commences at the upper part of the left ventricle, where it is about 3 cm.
In arteries they carry blood away from the heart did you notice the a there while veins carry blood back to the heart so again most of the time yes the arteries are carrying ~ but if you're sending blood from the heart to the lungs, ...
The vena cava returns de~ from the lower half of the body into the heart. Remember all veins except the pulmonary veins transport de~, and all arteries except the pulmonary arteries transport oeyxgnated blood.
Mammals have a double circulation, which means that the right hand side of the heart pumps de~ to the lungs in the pulmonary artery to pick up oxygen and release carbon dioxide. The ~ then returns to the left hand side of the heart in the pulmonary vein.
The pulmonary artery carries de~ to the lungs. In the lungs, gas exchange occurs, carbon dioxide diffuses out, oxygen diffuses in. Arterioles are small arteries that connect larger arteries with capillaries.
Not all arteries however contain arterial blood (highly ~). The pulmonary artery and its ramifications, arteries that carry blood from the right heart ventricle to the lungs, contain venous blood.

pulmonary circuit The system of blood vessels from the right ventricle of the heart to the lungs, transporting de~ and returning ~ from the lungs to the left atrium of the heart.
pulmonary Relating to or associated with lungs.
[L. pulmonis, lung]
In birds and mammals, a vein that carries ~ from the lungs to the left atrium of the heart, from which blood is pumped into the left ventricle and from there to the body tissues.
The gill capillaries converge into a vessel that carries ~ to capillary beds in the other organs (the systemic circulation) and back via veins to the atrium of the heart.
In fish, blood must pass through two capillary beds, the gill capillaries and systemic capillaries.
