The cardiac cycle.
The importance of cardiac cycle is to sustain human life.
The dark lines in a cardiac muscle when observed under a microscope are the intercarlated discs which are cell junctions ( desmosomes) these enables proper ion export ( mainly calcium ions )across a cardiac muscle and help it to contract as a syncitium. By - faireena singh( mbbs first year cmc)
Cardiac cycle
Cardiac cycle, which is made up of atrial and ventricular systole and diastole.
AV valves close during the systole phase of the cardiac cycle.
Cardiac cyccle is the term referring to all of the events related to the flow of blood that occur from the beginning of one heartbeat to the beginning of the next. The frequency of the cardiac cycle is the heart rate.
cardiac cycle
It depends on the heart rate. You take 72 beats per minute. Then the duration of one beat is 75 per minute. Then each beat will take 0.8 second to complete. This is taken duration of the cardiac cycle. You take 100 beats per minute. Then each beat will take 0.6 second to complete. This duration will be the duration of the cardiac cycle.
ventricular diastole
0.8 seconds
The auricles will contract during the systolic phase of the cardiac cycle. This is one of the numbers that is measured when a patient has their blood pressure taken.
