Carbon dioxide and oxygen diffuse between the air in the alveoli and the blood in the capillaries of the lung. Which partial pressures of these gases would make gaseous exchange possible?
- A$\text{CO}_2$ in alveolar air: $5.3\ \text{kPa}$; $\text{CO}_2$ in blood: $6.0\ \text{kPa}$; $\text{O}_2$ in alveolar air: $13.3\ \text{kPa}$; $\text{O}_2$ in blood: $13.9\ \text{kPa}$
- B$\text{CO}_2$ in alveolar air: $5.3\ \text{kPa}$; $\text{CO}_2$ in blood: $6.0\ \text{kPa}$; $\text{O}_2$ in alveolar air: $13.9\ \text{kPa}$; $\text{O}_2$ in blood: $5.3\ \text{kPa}$
- C$\text{CO}_2$ in alveolar air: $6.0\ \text{kPa}$; $\text{CO}_2$ in blood: $5.3\ \text{kPa}$; $\text{O}_2$ in alveolar air: $13.9\ \text{kPa}$; $\text{O}_2$ in blood: $5.3\ \text{kPa}$
- D$\text{CO}_2$ in alveolar air: $6.0\ \text{kPa}$; $\text{CO}_2$ in blood: $5.3\ \text{kPa}$; $\text{O}_2$ in alveolar air: $13.3\ \text{kPa}$; $\text{O}_2$ in blood: $13.9\ \text{kPa}$
