Q: Which equation correctly represents the calculation of tissue perfusion in the circulatory system?

$$\text{Tissue Perfusion} = \frac{\text{Cardiac Output} \times \text{Arterial Oxygen Content}}{\text{Tissue Demand}}$$

$$\text{Cardiac Output} = \text{Stroke Volume} \times \text{Heart Rate}$$

Q: Which equation best represents the relationship between ventilation and carbon dioxide transport?

$$\text{CO}_2 \text{ Elimination} = \text{Alveolar Ventilation} \times \text{CO}_2 \text{ Concentration}$$

Q: Which formula correctly represents the calculation of mean arterial pressure (MAP)?

$$\text{MAP} = \frac{1}{3} \times (\text{Systolic BP} - \text{Diastolic BP}) + \text{Diastolic BP}$$
