Does the exchange of carbon dioxide depend on the concentration of oxygen in the alveoli and the blood?
No. It depends on the concentration of carbon dioxide in the alveoli and the blood. The concentration of carbon dioxide in the capillaries of the alveoli is higher than the concentration of carbon dioxide in the air, so carbon dioxide in the capillaries of the alveoli diffuses out of the capillaries into the alveoli of the lungs and is exhaled.
How can the oxygen you bring into your body get to your circulatory system?
your lungs have structures called alveoli. The alveoli are surrounded by capillary beds which carry blood. The oxygen enters the alveoli when you inhale. The oxygen then diffuses from high concentration in your alveoli to low concentration the blood in the capillaries surrounding the alveoli.

Oxygen diffuses into the capillaries of the lungs because there is?
It diffuses because the concentration of oxygen in the capillaries is lower than the concentration of oxygen in the air (law of diffusion).
How does oxygen move into the bloodstreem?
The oxygen diffuses through the thin lining of the alveoli into the blood. It moves from the area of high oxygen concentration (the alveoli) to the area of low oxygen concentration (the blood).
Where does the exchange of oxygen take place?
Oxygen exchange takes place in the alveoli or "sacs" located in the lungs. It occurs through diffusion, which just simply means moving a particle from an area of higher concentration to an area of lower concentration.
What is the Diffusion of gases between alveoli and blood?
The Diffusion is the exchange of oxygen (O2) and carbon dioxide (CO2) between the alveoli and the blood. So blood that is pumping through the capillaries in the lungs has a low concentration of O2 and a high concentration of CO2, in the alveoli it is high concentration O2 low concentration CO2. Therefore the 2 gases exchange across the alveoli membrane by diffusion trying to establish a concentration gradient.
What is it called when oxygen moves from the lungs to the bloodstream?
diffusion - the natural movement of particles from high to low density. oxygen dissolves in a film of liquid water lining the alveoli (tiny air sacs in the lungs) and the wall of the alveoli and wall of the capillary (each 1 cell thick) into the blood in the capillary. the oxygen is moving from the high concentration of oxygen in the lung to the low concentration of oxygen in the blood. this low concentration is maintained in the blood since it continuously flows away and is replaced by oxygen poor blood. the high concentration of oxygen in the lungs is of course maintained by breathing in fresh air.
Where is the lowest concentration of oxygen in the body?
You have low concentration of oxygen in the veins. It is low in right side of the heart. It is supposed to be the lowest before it enters the alveoli of the lungs.
What explains the fact that the net movement of oxygen is always into the cell?
The net movement of oxygen into the cell is primarily driven by concentration gradients. Oxygen concentration is typically higher in the extracellular environment than inside the cell, creating a concentration gradient that favors the movement of oxygen from higher to lower concentration. This allows oxygen to diffuse into the cell until equilibrium is reached, ensuring the cell has sufficient oxygen for its metabolic needs.
How is blood oxygenated in the lungs?
The operating principle is a process called diffusion, which causes a substance to move from a region of high concentration to a region of lower concentration. Think of a squirt of perfume diffusing from a corner in a room until you can smell it everywhere in the room. Blood returning from the body to the lungs has a higher percentage of carbon dioxide (CO2) than the air inhaled into the lungs does. Conversely the concentration of oxygen (O2) in the inhaled air is greater than the concentration of O2 in the returning blood. Haemoglobin, which can (loosely) bond to both O2 and CO2, facilitates the exchange of gasses from respective regions of high concentration to the regions of lower concentration. Specifically, CO2 moves from the returning blood (higher concentration) to the air in the lungs (lower concentration) and oxygen moves in the other direction, thus oxygenating the blood.
How can air pollution cause emphysema?
The dust particles comes from air pollution and the concentration of carbondioxide is higher in it...so,when they enter in human body it start the destruction of the walls of alveoli...and the low concentration of oxygen disturb the gaseous exchange between alveoli and the capillries... By this exhalation process can't be done..In sever cases it can cause death...
