If end diastolic volume (EDV) is measured to be 120 ml/beat and the end systolic volume is measured to be 50 ml/beat, the stroke volume would be .

70  ml/beat.

Explanation:

Stroke volume may be defined as the volume of the blood that are pumped by the left ventricle in one contraction. The blood output can also be determined by knowing the stroke volume.

The stroke volume can be calculated by the formula as follows:

Stroke volume =  End diastolic volume - End systolic volume

Here, end diastolic volume = 120 and end systolic volume = 50.

Stroke volume = 120 - 50

Stroke volume = 70 ml/ beat.

Thus, the answer is 70 ml/ beat.

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
