| Contraction of the right and left atria forces blood past the right tricuspid and left bicuspid valves into the right and left ventricles, respectively. |
| The big curved glass roofs cover atria full of olive and mulberry trees that are overlooked from individual workplaces. |
| In addition to arterial baroreceptors, low-pressure baroreceptors exist and these respond to the degree of stretch of veins and the cardiac atria. |
| If a blood clot forms in the atria, it can exit the heart and block an artery in the brain, resulting in a stroke. |
| Anticoagulation is required afterwards because the atria continue to fibrillate and the risk of systemic embolism persists. |
| The atria receive blood from various parts of the body and pass it into the ventricles. |
