It is due to Diffusion Pressure Deficit, DPD for short.
When in the blood as oxyhemoglobin its DPD is almost twice that of cells, thus it passively diffuses into the cells from the blood.
A simpler way to look at is that products usually move from high density to low density areas via diffusion.
When attempting to answer this question to my students, I always refer back to this simple analogy: Think of the alveoli in the lungs like a bubbler in a fish tank. The alveoli release the oxygen into the blood much like the bubbler releases the oxygen into the water.
The blood in the capillaries comes in close contract with the thin membranes of the alveoli that simple diffusion allows oxygen to enter the body.
Diffusion means that something moves from a place of high concentration to a place of lower concentration. In this case oxygen is higher in the alveoli than in the capillaries.
Oxygen will diffuse faster as oxygen is a gas and bromine is a liquid
Plant releases oxygen. Oxygen molecules diffuse. Bear inhales.
leaves have pores on there underside that allow carbon dioxide in and let oxygen out
The blood gets oxygen from the air around us which is made of oxygen. When we breath in, the oxygen is taken into our lungs and then into our blood.
17.6 - 17.7 secconds
At the aveoli, the blood transfers CO2 and the hemoglobin on red blood cells picks up 02.
the lungs causes oxygen from the water to diffuse into the blood
Both oxygen and carbon dioxide diffuse from body tissues into the blood.
Carbon dioxide does.
Both oxygen and carbon dioxide diffuse from body tissues into the blood.
Gases are exchanged in the aveoli where oxygen goes in the blood stream while carbon dioxide goes in the aveoli.
the aveoli in the Lungs
Diffusion. In the lungs, oxygen will diffuse into de-oxygenated blood (oxygen was removed from the blood in the body) and carbon dioxide will diffuse out of the blood into the lungs and expelled from your body when you breathe out.
The alveoli are the site of carbon dioxide and oxygen exchange between the air and the blood.
There are two cells that oxygen must diffuse from. Once the oxygen enters the lungs, it is pushed to the aveoli, which is one cell thick and where the gas exchange occurs. Surrounding it are capillaries, which is also one cell thick. Here, oxygen moves across the two cells while the CO2 exits the red blood cell to exit the lungs.
The brochiole's function is to allow oxygen to pass into the aveoli (air sacks covered in capillaries) where the oxygen can then enter your blood stream.
