Systolic Blood Pressure

Answers:
1. The systolic blood pressure measured in the auscultatory method is more accurate than that measured in the palpitation method because the palpitation method is prone to more human errors such as how strong the pulse is, where it is located, how hard the wrist is pressed during palpitation and a stethoscope which is used in the auscultatory method is more sensitive than feeling a pulse. Hearing the pulse involves less human error than feeling it. 2. The maximum pressure exerted when blood is ejected into the aorta during contraction of the left ventricle is known as Systolic blood pressure. 
The minimum pressure which is exerted in the arteries as a result of ventricular relaxation is known as Diastolic blood Pressure.
The difference between systolic and diastolic blood pressure is known as Pulse pressure.
 Pulse pressure = Systolic pressure- Diastolic pressure 
The Systolic, Diastolic Blood Pressure and Pulse pressure are affected by:
1. Blood volume- This is the volume of blood available in the system. More volume means that more work is done by the ventricles, thus blood pressure is higher
2. Cardiac
As the subject moved from a lying to a standing position an immediate decrease in Systolic from 116mmHg to 68mmHg and Diastolic BP from 56 mmHg to 32 mmHg is observed. The mean arterial pressure(MAP) decreased from 74 to 43 mmHg. However, the heart rate increased from 80 to 93 bmp. This was due to the pooling of blood in the lower limbs subsequently decreasing venous return, thus causing stroke volume and cardiac output to fall.Therefore a decrease in the MAP was observed according to the equation: MAP = CO X TPR. 
After 1 minute, the systolic, diastolic BP, MAP increased to 105,53,67 mmHg respectively and heart rate decreased to 93 bmp. This trend continued for the next 2 minutes until these values stabilised at the end of the 3rd minute.The changes in the values were a result of compensatory changes in the
