List the factors that impact Cardiac Output Heart Rate Stroke Volume Arterial Pressure Peripheral Vascular Resistance
Homework Answers
Answer: Cardiac output is the number of heart beats per minute. The normal heart rate is 60 to 100 beats per minute. Cardiac output is influenced by stroke volume, arterial pressure. Chronic blood pressure, smoking, poor exercise level affect the cardiac output.
Stroke volume can be defined as the measurement of the volume of blood that is being forced applied from the left ventricle in the heart contractions. Factors such as heart's ability to contract, the amount of force of contraction, the volume of blood influences the Stoke volume. It is measured as SV = EDV - ESV.
Arterial pressure is the amount of pressure exerted by the blood on the walls of the artery. Heart rate, stroke, peripheral resistance influences the arterial blood pressure.
Peripheral vascular resistance is influenced by Autonomic activity i.e. sympathetic activity, constricts peripheral arteries etc.

5. Consider the following equation: Stroke volume = cardiac output / heart rate If a heart fills up to 200ml of blood before contraction, and leaves 50ml in the heart after contraction, what would be the stroke volume? If the heart rate is 80 beats per minute, what would the calculated cardiac output? If the total peripheral resistance increases, what is likely to happen to the stroke volume? (Please address all three questions and include units to receive full credit.)...

Experiment was conducted on bodily exercise of an individual and the cardiac output of such individual rises to 25 L min1 from a resting Level of 5 L min-1. The heart rate of a well-trained athlete might rise from 60 beats per minute to 105 beats per minute and the mean arterial pressure may rise from 100 to 300 mmHg, whereas the heart rate of a secondary person might rise from 72 beats per minute to 125 beats per minute...
