Answer:Normally, arteries are depicted in red and veins are depicted in blue. The pulmonary arteries are colored BLUE because they contain DEOXYGENATED blood that flows to the lungs to pick up OXYGEN and unload CARBONDIOXIDE. The pulmonary arteries exit the heart from the RIGHT VENTRICLE (chamber). The pulmonary veins are colored RED because they carry freshly OXYGENATED blood back to the LEFT ATRIUM (chamber) of the heart.

Explanation:

The circulatory system ensures a continuous flow of blood to all body cells. The heart is a muscular organ that is divided into four chambers which includes the right atrium, left atrium, right ventricle and the left ventricle.

The heart pumps blood into vessels that vary in structure, size and function and there are several types which includes:

--> arteries

--> arterioles

--> capillaries,

--> venules and veins.

The ARTERIES are the blood vessels that transport blood away from the heart. They are normally depicted in red because they carry oxygenated blood with the exception of the PULMONARY ARTERY which carries deoxygenated blood to the lungs.

The VEINS are blood vessels that return blood to the heart. They are normally depicted in blue with the exception of the PULMONARY VEIN because they carry deoxygenated blood from the lungs to the heart.
