| h English (en) | ====Coronary circulation==== {{Main|Coronary circulation}} The heart itself is supplied with oxygen and nutrients through a small "loop" of the systemic circulation and derives very little from the blood contained within the four chambers. The coronary circulation system provides a blood supply to the [[myocardium|heart muscle]] itself. The coronary circulation begins near the origin of the aorta by two [[coronary arteries]]: the [[right coronary artery]] and the [[left coronary artery]]. After nourishing the heart muscle, blood returns through the coronary veins into the [[coronary sinus]] and from this one into the right atrium. Backflow of blood through its opening during [[atrial systole]] is prevented by the [[Thebesian valve]]. The [[smallest cardiac veins]] drain directly into the heart chambers. |
| h Japanese (ja) | ====冠動脈循環==== {{Main/ja|Coronary circulation/ja}} 心臓自体は、体循環の小さな "ループ"を通じて酸素と栄養を供給され、4つの部屋の中にある血液からはほとんど栄養を得られない。冠循環は[[myocardium/ja|心筋]]そのものに血液を供給する。冠動脈循環は、大動脈の起始部付近から[[right coronary artery/ja|右冠動脈]]と[[left coronary artery/ja|左冠動脈]]の2本の[[coronary arteries/ja|冠動脈]]によって始まる。心筋に栄養を与えた後、血液は冠静脈を通って[[coronary sinus/ja|冠静脈洞]]に戻り、ここから右心房に入る。[[atrial systole/ja|心房収縮期]]の血液の逆流は、[[Thebesian valve/ja|テーベ弁]]によって阻止される。[[smallest cardiac veins/ja|最も細い心臓静脈]]は直接心室に流れ込む。 |
