In vertebrates, the circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the body. [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).

This article contains a list of organs in the human body. It is widely believed that there are 79 organs (this number goes up if you count each bone and muscle as an organ on their own, which is becoming a more common practice [1] [2]); however, there is no universal standard definition of what constitutes an organ, and some tissue groups' status as one is debated. [3]
This is a list of notable body parts of people. It includes specific, individual instances of organs and appendages which are famous in their own regard. Many noted body parts are of dubious provenance [1] and most were separated from their bodies post-mortem. [2] In some faiths, veneration of the dead may include the preservation of body parts ...
End arteries can exist when no anastomosis exists or when an anastomosis exists but is incapable of providing a sufficient supply of blood, thus the two types of end arteries are: Anatomic (true) end artery: No anastomoses. Functional end artery: Ineffectual anastomoses. An example of a true terminal artery is that which supplies the retina.
Compartment syndrome is a condition in which increased pressure within one of the body's anatomical compartments results in insufficient blood supply to tissue within that space. [31] [32] There are two main types: acute and chronic. [31] Compartments of the leg or arm are most commonly involved. [33]
The heart propels the circulation of the blood, which serves as a "transportation system" to transfer oxygen, fuel, nutrients, waste products, immune cells and signaling molecules (i.e. hormones) from one part of the body to another. Paths of blood circulation within the human body can be divided into two circuits: the pulmonary circuit, which ...
Grafting refers to a surgical procedure to move tissue from one site to another on the body, or from another creature, without bringing its own blood supply with it. Instead, a new blood supply grows in after it is placed. A similar technique where tissue is transferred with the blood supply intact is called a flap. In some instances, a graft ...
