The word you provided appears to be a Polish phrase asking about how many chambers the heart has. The answer in Polish: Serce człowieka ma cztery jamy: dwa przedsionki i dwie komory. Explanation

• The heart is divided into four chambers: right atrium, left atrium, right ventricle, and left ventricle.
• Atrioventricular and semilunar valves prevent backflow, ensuring unidirectional blood flow.
• Blood circulates through two major circuits: the systemic (large) circuit and the pulmonary (small) circuit.
