The volume of blood pumped out by each ventricle per cardiac cycle is called …..X……which is about …….Y……… . Select the correct option for X and Y.

Options

A. X - Stroke Volume , Y - 70 ml
B. X - Cardiac output , Y - 50 ml
C. X - lsovolumetric Systole , Y - 50 ml
D. X - Isovolumetric Diastole , Y - 30ml

Answer

To solve the question, we need to identify the terms that describe the volume of blood pumped out by each ventricle per cardiac cycle and its approximate value.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the term used to describe the volume of blood pumped out by each ventricle during one cardiac cycle and its approximate value.

2. **Identifying the Term**: The volume of blood pumped out by each ventricle per cardiac cycle is known as **stroke volume**. This is a key term in cardiovascular physiology.

3. **Determining the Value**: The typical value for stroke volume in a healthy adult is approximately **70 ml**. This value can vary based on factors like age, fitness level, and health status, but 70 ml is a commonly accepted average.

4. **Final Answer**: Therefore, the correct options for X and Y are:
- X = Stroke Volume
- Y = 70 ml
