James went to the doctor for his annual physical exam. the medical assistant took his pulse and
blood pressure. both were normal: pulse 75 beats/minute; blood pressure 120/80 mmhg. since
he is basically healthy, his stroke volume is consistent at 70 milliliters/beat. calculate james'
cardiac output.

Cardiac output is the product of stroke volume and heart rate.

Cardiac output (CO) = Stroke volume (SV) X heart rate (HR)

James stroke volume  = 70 milliliters/beat and heart rate = 75 beats/minute

CO= 70 x 75 = 5250

James cardiac output CO = 5250 mL/minute

Explanation:

The cardiac function can be assessed by measuring the cardiac output. Cardiac output denotes the “total amount of blood pumped by the heart in one minute”. It is the amount of blood flowing through the circulatory system in one minute and depends on the two variables – stroke volume and heart rate and is the product of both the variables.

Stroke volume is the “total amount of blood pumped out by the left ventricle during one contraction”.

Heart rate refers to the “number of times the heart beats in a minute” or the “number of contractions of the ventricles in a minute".

auricle

explanation:

the flaps on the front of the atria are called the auricle.
