Which of the following correctly describes the pressure of oxygen and carbon dioxide in the lungs? A. Oxygen: Higher in the capillaries Carbon Dioxide: Higher in the alveoli

B. Oxygen: Lower in the capillaries Carbon Dioxide: Higher in the alveoli

C. Oxygen: Higher in the capillaries Carbon Dioxide: Lower in the alveoli

D. Oxygen: Lower in the capillaries Carbon Dioxide: Lower in the alveoli

option a is correct i.e.

explanation:

in context to the membrane of nerve impulse, the outer membrane of neuron is semi permeable that is only sodium ions can pass through the membrane i.e. smaller ions can pass through the membrane while larger ions cannot pass through it.
