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...

energy needs of athletes
Skeletal muscles, which move bones, consist of cells fused into
long fibers. These muscle fibers can increase in size when
contracted, which is what happens as a result of some exercise.
This animation shows the structure of vertebrate skeletal muscles.
It starts at a large scale, showing the muscles of a human upper
arm, and then gradually zooms in to smaller and smaller levels,...

or perform normal tasks because she became rapidly fatigued. She was 5 feet 4 inches tall, and weighed only 82 pounds although her daily calorie intake was 3,000 to 3,500 calories. Her intestinal function and absorption appeared normal. Her blood glucose, blood CO 2 , and red blood cell counts were normal, but her breathing rate and heart rate were increased. On average, her temperature was elevated a degree. She drank large amounts of water and perspired profusely with no...

2. Suppose a car travels 108 km at a speed of 20.0 m/s, and uses
2.20 gallons of gasoline. Only 30% of the gasoline goes into useful
work by the force that keeps the car moving at constant speed
despite friction. (The energy content of gasoline is 1.3 ✕
108 J per gallon.)
