The process used to move oxygen into the capillaries of the lungs is called diffusion. Oxygen in the alveoli of the lungs moves across the thin walls of the alveoli and the capillaries by diffusion, from an area of high concentration to an area of low concentration, facilitated by the pressure difference between the alveoli and the blood in the capillaries.
Oxygen moves from the lungs to the blood through a process called diffusion. This occurs at the alveoli in the lungs, where oxygen in the air sacs diffuses across the alveolar membrane into the capillaries surrounding the alveoli. From there, the oxygen binds to hemoglobin in red blood cells for transport to the body's tissues.
Oxygen enters the lungs and diffuses across the thin walls of the alveoli (air sacs) into the surrounding capillaries. Here, oxygen binds to hemoglobin in the red blood cells, forming oxyhemoglobin. This oxygenated blood is then pumped by the heart to the rest of the body.
We should first start at the beginning. As you know, you breathe oxygen in when you contract your diaphragm and air fills your lungs. The walls of your lungs are filled with capillaries (tiny blood vessels) that look kind of like feathers. If you were to stretch out the entire surface area of the capillaries in your lungs, it would be about equal to the size of a tennis court! So, in the capillaries flows your de-oxygenated blood. It has been on a complete cycle through your body, and is now low on O2. When the erythrocytes (red blood cells) enter the capillaries, the oxygen gets chemically stuck to them. It attaches to a large protein called hemoglobin, a 4 piece protein with a single iron atom at the center. (this explains why an iron deficiency can lead to anemia, or a low red blood cell count) Each red blood cell contains as many, many hemoglobin molecules. The oxygen is at a HIGH concentration in your lungs, and so flows into the LOW concentration in the blood. As the laws of nature would predict, as the red blood cells move into areas of lower oxygen concentration, the oxygen leaves the hemoglobin and enters its new tissue.
Oxygen moves into the blood by diffusing across the respiratory membrane in the lungs. This process occurs in the alveoli, tiny air sacs where oxygen enters the bloodstream from the surrounding air. From there, oxygen binds to hemoglobin in red blood cells for transportation to tissues throughout the body.
During respiration, oxygen enters the body through the respiratory system (nose, trachea, lungs) and reaches the alveoli where it diffuses into the bloodstream. The oxygen is then transported by red blood cells to tissues and cells where it is used to produce energy through cellular respiration. Carbon dioxide, a waste product of this process, is carried back to the lungs to be exhaled.
Oxygen moves from the lungs to the blood through a process called diffusion. This occurs at the alveoli in the lungs, where oxygen in the air sacs diffuses across the alveolar membrane into the capillaries surrounding the alveoli. From there, the oxygen binds to hemoglobin in red blood cells for transport to the body's tissues.
Through diffusion. There is less oxygen in the cells as opposed to the capillaries, so through simple diffusion, the oxygen goes from an area of high concentration to lower concentration.

No, the movement of oxygen from the lungs to the bloodstream is not by osmosis. Instead, it occurs through a process called diffusion, where oxygen molecules move from an area of high concentration (in the lungs) to an area of lower concentration (in the bloodstream) to reach equilibrium.
Red blood cells do not "move files." Instead, they circulate throughout the body to transport oxygen from the lungs to tissues and remove carbon dioxide for excretion. This process occurs in the bloodstream as the cells travel through the arteries, capillaries, and veins.
The alveoli are the hollow spheres of cells within the lungs where oxygen and carbon dioxide are exchanged. They are thin-walled, and closely associated with the thin-walled capillaries that surround them. Oxygen and carbon dioxide diffuse across these thin walls to move from the blood to the lungs.
There are many capillaries in your lungs, digestive system and muscles because each of these locations require blood to be transfered to individual cells snd capillaries are the smallest vessels that can do this.In your lungs capillaries connect to the alveoli and enable gas exchange within the body.In your digestive system capillaries enables food to be passed through the walls of the intestines.In your muscles capillaries deliver a fresh supply of oxygen to each cell and remove any bi-products enabling you to move sufficiently.
the answer to apex is passive.

Oxygen enters cells through diffusion, where it moves from areas of high concentration in the bloodstream to low concentration in cells. Carbon dioxide exits cells through the same process, diffusing from high concentration in cells to low concentration in the bloodstream for removal by the lungs.
They are the alveoli.
