Explanation / Answer

1. Option

Atrium is the upper chamber of heart. When it contracts semilunar valve opens. Then blood fills the ventricles. Next the ventricles contract which ejects the blood out of heart. In this phase the isovolumetric contracts too. Semi lunar valve closes.

2. Option 2

Ventricle is the lower chamber of the heart. During ventricular systole, semi lunar valve opens and the ventricles contract and Atria relaxes. From the ventricle the blood is pumped to aorta and pulmonary valves.
