Final answer:
Cardiac output is the amount of blood the heart pumps in 1 minute. It is calculated by multiplying heart rate by stroke volume. The normal cardiac output for a resting adult is about 5.25 liters per minute.
Step-by-step explanation:
The amount of blood the heart pumps in 1 minute is called cardiac output. Cardiac output is calculated by multiplying the heart rate (HR) by the stroke volume (SV). Normal cardiac output varies depending on factors such as age, fitness level, and overall health. In a resting adult, the average cardiac output is about 5.25 liters per minute.
