Question 17 (1 point)
End Diastolic Volume/Preload in a ventricle is typically:
A) 200 mL
B) 130 mL
C) 70 mL
D) 40 mL
Question 18 (1 point)
(1) usten
During ventricular ejection, the ventricles pump out all the blood that was inside
them, before relaxing to receive more blood.
True
False

The end diastolic volume (EDV) in a ventricle typically ranges from 120 to 140 mL in a healthy adult, with 130 mL being a commonly cited figure. This volume reflects the amount of blood in the ventricle just before contraction, playing a key role in determining the stroke volume and overall cardiac output.

During ventricular ejection, it’s a common misconception that the ventricles pump out all the blood they contain. In reality, the heart retains a certain volume of blood called the end-systolic volume (ESV) after each contraction, which allows for a more efficient and continuous cycle of filling and pumping. So the correct answer here would be False!
