The answer is two cells. Alveolus is having single flat cell wall and the capillary having the single flat cell wall.

How does oxygen circulate in the body?
Oxygen circulates through the body in blood. A molecule of oxygen (O2) from the lungs binds loosely to a molecule of hemoglobin in a red blood cell. The red blood cell travels through the capillaries and the oxygen molecule is released from the hemoglobin and is delivered to the cells.
How many times does an oxygen molecule cross a plasma membrane when moving from inside an alveolus to the hemoglobin of a red blood cell and what are the plasma membranes?
1. Into the cell of the alveolus 2.+3. Out of the alvealus into cell of the capillary wall 4. Out of the cell of the capillary wall and into blood plasma 5. Into the red blood cell. So 5.
Where does oxygen into the blood and carbon dioxide pass out of the blood?
alveoli
How is oxygen carried through the bloodstream?
Oxygen can travel dissolved in the plasma, but mostly it binds to a specific molecule - hemoglobin - found in red blood cells.
What is the name of the air sacs that oxygen from the air to pass into your blood?
alveolus (alveoli)plural. it's purpose is to exchange gases between the air and the body.
How many oxygen molecules does have to pass through from the alveolus to get into the blood?
3 or 4
The life cycle of an oxygen molecule?
an oxygen molecule is inhaled and then goes through the blood
Will O2 diffuse from air to blood or from blood to the alveolar air?
It will be absorbed from the air into your lungs. Then when it reachs the alveolus it will diffuse from the alveolus into the blood capillaries down an oxygen concentration through diffusion where it will combine with the heamoglobin in the Red Blood Cells.
Because there is more oxygen in an alveolus than in the blood around it oxygen diffuses?
When there is more oxygen in an alveolus than in the blood around it oxygen diffuses from the capillaries to the veins. This is due to the high concentration of oxygen in the alveoli.

What makes the concentration of oxygen low in the alveolus?
Oxygen diffuses into the blood capillary

What is the of Alveolus?
The alveolus is a air sac that holds the oxygen. It squashes the oxygen molecules so they diffuse from the alveolus into the capillary. From there, they attach themselves to deoxygenated Red Blood Cells. The oxygen in the blood plasma are also squashed and are diffused. They go from the capillary to the alveoli to get breathed out. The alveoli transfers the oxygen to the lung capillaries and oxygenates the blood, then it is breathed out as Carbon Dioxide.
What is the site where oxygen enters the pulmonary blood?
Oxygen enters the blood in the alveoli of the lungs

What artery or veins carry oxygen-poor blood to the lungs?
Pulmonary alveolus!
Place where oxygen and carbon dioxide exchanged between air and blood?
alveolus
