Homework Answers
The compression of the coronary arteries increase when the heart beats at a faster rate due to increase in the contraction of the heart. When the heart rate is higher like during exercise, there is increase in systole which is ejecting the blood into aorta and pulmonary trunk and when there is increase in heart muscle contraction during refilling of the blood. As the systole takes place rapidly, it tends to increase the heart rate and hence leads to increase in the time for the total amount of compression of the coronary arteries.

Each time your heart beats, your blood pressure first increases and then decreases as the heart rests between beats. The maximum and minimum blood pressures are calledthe systolic and diastolic pressures, respectively. Your blood pressure reading is written as systolic/diastolic. A reading of 120/80 is considered normal. A certainperson's blood pressure is modeled by the function p(t)=115 25sin (160pit) where p(t) is the pressure in mmHg, at time t measured in minutes. a) Find the period of pb) FInd the...

Problem 2 (Health Data Measurements) One of the most important measurements related to your cardiovascular health is your heart rate, which is usually reported in beats per minute (BPM). If you go to the doctor, they usually take a single measurement of this quantity.
