Exam 13: Cardiovascular System

An increase in the time that the heart spends in diastole has the potential to increase stroke volume.

Capillaries merge to form venules, which merge to form veins that carry blood back to the atria.

The volume of blood discharged from the ventricle with each heartbeat is called __________.

An abnormally slow heart rate (fewer than 60 beats per minute) is called __________.

A resting heart rate that exceeds 100 beats per minute is called __________.

If someone's cardiac output is 4.5 liters per minute, their heart rate may be 90 beats per minute with a stroke volume of 50 ml.

Arteries carry blood away from the heart.
