Calculate the cardiac output if heart rate (HR) is 90 beats per minute, stroke volume (SV) is 110 ml/beat, end diastolic volume

Yakvenalex [24]

ANSWER: None of the above options are correct.

Cardiac Output(CO) = Stroke Volume(SV) × Heart Rate(HR)

Therefore where HR= 90bpm and SV= 110ml/min,

CO = 90 × 110 = 9900ml/min or 9.9L/min.

EXPLANATION:

CARDIAC OUTPUT is the volume of blood being pumped by the heart into the systemic circulation per minute.

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

STROKE VOLUME is the amount of blood pumped out by the left ventricle in each contraction.

HEART RATE is the count of the number of times the heart beats per minute.

Explanation:

All you have to do is list the belts and planets in inverse order:

$\displaystyle Mercury \\ Venus \\ Earth \\ Mars \\ \\ asteroid belt \\ \\ Jupiter \\ Saturn \\ Uranus \\ Neptune \\ \\ kuiper\:belt \\ \\ Pluto\:[dwarf\:planet]$

Now, if you recall the acronym correctly, it would be a WHOLE LOT EASIER:

My Very, Eager [or Excellent] Mother Just Served Us Nacho Pizza.

Each first lettre of a wourd represents the planets, but what they do not tell you is that the kuiper belt runs beyond the planet Neptune, and the asteroid belt separates the Jovian Planets from the Terrestrial Planets. That is to say, they it runs between Jupiter and Mars.

So, with all of this information given to you, you now should have a clue of what the answer is.

I am delighted to assist you at any time.
