Valves can be found in the heart. They sit between the Atria and the Ventricles and help aid cardiovascular activity.

Why are red blood cells built to carry oxygen?
Something has to do this job, so if it wasn't red blood cells then it'd need to be something else. Unless, of course, mammals had evolved in some other way which did not have a circulatory system.
How the circulatory system work with the integumentary system?
One of the functions of the integumentary system is to regulate body temperature. It does so by using the APM (arrector pili muscle) to raise arm hairs and help increase body temperature when cold by using this muscle contraction and to help trap and warm air underneath these hairs.The circulatory system is also responsible for helping regulate body temperature. It does so by allowing the blood vessels to vasodilate (widen) or vaso constrict (become smaller). When the blood vessels dilate what else does the heat escape through than the integumentary system (the skin).
