For example, the partial pressure of O2 in the alveoli is 104 mmHg and the partial pressure of O2 in the blood in the pulmonary capillaries is 40 mmHg. Will O2 continue to diffuse from the alveoli into the blood until the partial pressure of O2 in the alveoli is 0 mmHg?arrow_forward

Which of these is always negative in a healthy individual during normal breathing?

In other words, how is a lower pressure gradient in the pulmonary circuit advantageous for physiological functioning?arrow_forward
