Why are red blood cells different in shape-slightly-in the alveolus of a human lung?

The bonding of oxygen to hemoglobin within it causes it to change shape slightly.

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.
How many cells does an oxygen molecule have to pass through to get from an alveolus into the blood?
The answer is two cells. Alveolus is having single flat cell wall and the capillary having the single flat cell wall.
Why is the distance between the air in an alveolus and the blood in an alveolar capillary is less than 11000th of a millimetre?
Around the lungs,the blood is separated from the air inside each alveolus by only two cell layers; the cells making up the wall of the alveolus and the capillary wall itself. This is a distance of less than a thousandth of a millimetre. Because the air in the alveolus has a higer concentration of oxygen than the blood entering the capillary network, oxygen diffuses from the air across the wall of the alveolus and into the blood. That is why the distance is important.
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.
How can the blockage of the alveolus be removed?
Alveolar macrophage cells work to clear particles from the alveolus by phagocytosis. If this process is overcome by continued build up of particles then the alveolus becomes damaged. Once an alveolus is blocked there isn't much you can do.
Why are there a large number of blood vessels around each alveolus?
because the oxygen needs to pass through alveoli and there is alot of cells around to be transported!!
What are the 3 different blood cells?
Red Blood Cells, White Blood Cells, and Platelets.
Are alveoli cells?
Yes. Alveolus is composed of many cells that work for a common function, to take out carbon dioxide and oxygenate the blood.
How does CO2 travel from tissue to alveolus apart from dissolving in plasma?
Apart from dissolving in plasma, CO2 travels from tissue to alveolus in hemoglobin. Much of the carbon dioxide go into the red blood cells. Then the carbon dioxide binds with water, forming carbonic acid.
What are the two different types of blood?
white blood cells and red blood cells
What is the function of the moisture layer inside an 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.
Why doesn't different cells have different DNA?
Different cells have different parts, depending on their job in the body. That's why red blood cells differ from white blood cells; a red blood cell has mitochondria and vacuoles. The white one does not.
