Expert Answer

Step 1

The cardiac cycle contains two phases, the systole, and the diastole. In the systole phase blood is pumped from the heart, and in the diastole phase, the heart gets filled with the blood. Moreover, systole and diastole are further divided into two more phases. Systole is divided into isovolumetric contraction, and systolic ejection, while diastole is divided into isovolumetric relaxation, and ventricular filling.

Mean arterial pressure is the average blood pressure of the living being that should be maintained in a single cardiac cycle.

Step 2

The first option is increased sympathetic activity to compensate for the decreased mean arterial pressure. The sympathetic nervous system helps in maintaining blood pressure. When the blood pressure decreases, the sympathetic nervous system starts the baroreflex mechanism to increase blood pressure. Hence, this option is correct.

The second option is all of the above are correct. From the given options all are correct. Hence, this option is correct.

The third option is increased hypotension. Hypotension i...
