Assume that the left ventricle of a child's heart has an edv=90 ml, and esv=60ml, and a cardiac output of 2,400 ml/min. his sv is ml/beat and his hr is bpm.

Assume that the left ventricle of a child's heart has an EDV=90 mL, and ESV=60mL, and a cardiac output of 2,400 mL/min. His SV is _30_ mL/beat and his HR is _80_ bpm.

Explanation:

Calculation can be achieved by using this formula.

Stroke Volume (SV) = End diastolic volume – End systolic volume

Given that  

End diastolic volume = 90

End systolic volume = 60

Calculations

Stroke Volume (SV) = 90 - 60

Stroke Volume (SV) = 30mL / beat

Heart rate can be calculated using this formula:

Heart Rate = Cardiac Output / Stroke Volume

Given that

Cardiac Output = 2400 mL / min

Stroke Volume (SV) = 30mL / beat

Calculations

Heart Rate (HR) = 2400 / 30

Heart Rate (HR) = 80 m bpm

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells
