[1] [2] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia meaning heart, and Latin vascula meaning vessels).
The discovery continues to advance the fields of archaeology and science in the 21st century, particularly in the area of preservation of ancient human remains. Scientists in 2003 developed a "secret compound" that was injected into Xin Zhui's still existing blood vessels to assure her preservation. [10]
It notes that the heart is the center of blood supply, and attached to it are vessels for every member of the body.

ED is a fairly common health condition associated with heart disease, high blood pressure and blood flow. It affects an estimated 30 million to 50 million men nationally.
In anatomy, the venae cavae (/ ˈ v iː n i ˈ k eɪ v i /; [1] sg. vena cava / ˈ v iː n ə ˈ k eɪ v ə /; from Latin ' hollow veins ') [2] are two large veins (great vessels) that return deoxygenated blood from the body into the heart.
