What happens after oxygen diffuses into the blood capillary from the alveolus? (more than 1 answer)
Combine with haemoglobin
Dissolves in blood plasma
Diffuses into red blood cell
Form oxyhaemoglobin
Oxyhaemoglobin is an unstable compound. What happens when it reaches the body cells?
Absorb CO2
Release O2 into the cell
Absorb more O2
Release CO2 into the cell
What is the function of oxygen for the cell?
Forms glucose
Breathing
Cellular respiration
Excretion
To allow respiratory gases dissolves and diffuse into blood capillary. What is the adaptation of alveolar structure?
One-cell thick
High surface area
Large network of blood capillary
Moist surface
Which of the following is NOT the adaptation of the alveolus to increase the efficiency of gaseous exchange?
Moist surface
Thick wall
Large network of blood capillary
Large surface area
Aiman has reached at the top of mount Kinabalu. What happens to the efficiency of gases exchange in his alveolus at that time?
Increases
Decreases
No change
