Pressure Reflexes and Mean Arterial Pressure.  

When Mean Arterial Pressure rises Baroreceptors fire, signal goes to the medulla, parasympathetic activity goes up, Sympathetic Activity goes down, which ends up resulting in an decrease in cardiac output and peripheral resistance and so decrease Mean Arterial Pressure.

- Cardiac Cycle.

Cardiac Cycle.

The cardiac cycle is a term referring to all or any of the events related to the flow or blood pressure that occurs from the beginning of one heartbeat to the beginning of the next. (1)

A single cycle of cardiac activity can be divided into two basic phases - diastole and systole.

Have you heard your heart beat?

What is the sound like? Yes, it sounds like 'lubb-dubb', 'lubb-dubb'! 

This sound is produced when the heart produces a pressure when it beats.

Now, what causes the beating of the heart? The sequence of events that take place during a single heart beat is known as the Cardiac Cycle. It is not so simple. It is a complex process which involves a sequence of activities and that too within 0.8 sec.
