How do the atrioventricular valves and the semilunar valves behave during atrial systole and ventricular systole?
- Aatrial systole: atrioventricular valves open, semilunar valves closed; ventricular systole: atrioventricular valves closed, semilunar valves open
- Batrial systole: atrioventricular valves open, semilunar valves closed; ventricular systole: atrioventricular valves open, semilunar valves open
- Catrial systole: atrioventricular valves closed, semilunar valves open; ventricular systole: atrioventricular valves closed, semilunar valves closed
- Datrial systole: atrioventricular valves closed, semilunar valves open; ventricular systole: atrioventricular valves open, semilunar valves closed
