There are multiple definitions:

1. mitral valve(English)

   • also called the bicuspid valve, is a crucial one-way valve between the left atrium and left ventricle that ensures blood flows from the lungs into the ventricle and then to the body, preventing backward leakage. Mitral valve disease is a frequent cause of heart failure and death

2. minute ventilation(English)

   • defined as the amount of air breathed per minute, which equals about 6 liters (about 2 liters stay in the anatomic dead space consisting of the upper airway and the mouth, and 4 liters participate in gas exchange in the millions of alveoli constituting alveolar ventilation)

6. main vessel(English)

   • the coronary circulation is supplied by two main epicardial vessels originating from the aortic root: the Left Main Coronary Artery (LMCA) and the Right Coronary Artery (RCA). The LMCA quickly bifurcates into the Left Anterior Descending (LAD) and Circumflex (LCx) arteries, serving the left heart, while the RCA serves the right heart and often the posterior septum
