At a resting pulse rate of 77 beats per minute, the human heart typically pumps about 71 mL of blood per beat. Blood has a density of 1060 kg/m3. Circulating all of the blood in the body through the heart takes about 1 min for a person at rest. Approximately how much blood is in the body? volume of blood in body On average, what mass of blood does the heart pump with each heart beat? kg mass per heart...

Research discovered that the average heart rate of a sweeper in curling (a Winter Olympic sport) is 191 beats per minute. Assume the heart rate for a sweeper follows the normal distribution with a standard deviation of 5 beats per minute. Complete parts a through d below. a. What is the probability that a sweeper's heart rate is more than 194 beats per minute? 0.2743 (Round...

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...

Heart rate during laughter. Laughter is often called “the best medicine,” since studies have shown that laughter can reduce muscle tension and increase oxygenation of the blood. In the International Journal of Obesity (Jan. 2007), researchers at Vanderbilt University investigated the physiological changes that accompany laughter. Ninety subjects (18–34 years old) watched film clips designed to evoke laughter. During the laughing period, the researchers measured the heart rate (beats per minute) of each subject, with the following summary results: Mean...
