What would be the cardiac output of a person having 72 heart beats per minute and a stroke volume of 50 mL ?

Options

A. 360 mL
B. 3600 mL
C. 7200 mL
D. 5000 mL

Explanation

To find the cardiac output of a person with a heart rate of 72 beats per minute and a stroke volume of 50 mL, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Formula for Cardiac Output**:
Cardiac output (CO) is calculated using the formula:
\[ \text{Cardiac Output (CO)} = \text{Stroke Volume (SV)} \times \text{Heart Rate (HR)} \]

2. **Identify the Given Values**:
- Stroke Volume (SV) = 50 mL
- Heart Rate (HR) = 72 beats per minute

3. **Substitute the Values into the Formula**:
Plug the values into the cardiac output formula:
\[ \text{CO} = 50 \, \text{mL} \times 72 \, \text{beats/min} \]

4. **Perform the Calculation**:
Multiply the stroke volume by the heart rate:
\[ \text{CO} = 50 \times 72 = 3600 \, \text{mL/min} \]

5. **State the Final Answer**:
The cardiac output of the person is 3600 mL/min.

### Conclusion:
The correct answer is 3600 mL/min.
