Cardiovascular system (C0007226) | |
|---|---|
| Definition (MSH) | The HEART and the BLOOD VESSELS by which BLOOD is pumped and circulated through the body. |
| Definition (CSP) | bodily system consisting of the heart, blood vessels, and blood that circulates blood throughout the body, delivers nutrients and other essential materials to cells, and removes waste products. |
| Definition (NCI) | The system that contains the heart and the blood vessels and moves blood throughout the body. This system helps tissues get enough oxygen and nutrients, and it helps them get rid of waste products. The lymph system, which connects with the blood system, is often considered part of the circulatory system. |
| Definition (NCI) | Having to do with the heart and blood vessels. |
| Definition (NCI) | Relating to the heart and the blood vessels or the circulation. |
| Definition (NCI) | Pertaining to the heart or blood vessels. |
