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.
The cornea in the eye does not receive oxygen from blood. Instead, it gets its oxygen directly from the air.
blood gets a fresh dose of oxygen from the lungs and a fresh ration of food from the liver
Oxygen is inhaled through the lungs where it diffuses across the lung membrane into tiny blood vessels called capillaries. From there, oxygen binds to hemoglobin in red blood cells and is transported throughout the body to be used by cells for energy production.
Oxygen is inhaled through the lungs and enters the bloodstream where it binds to hemoglobin in red blood cells. The oxygen-rich blood is then pumped by the heart to deliver oxygen to tissues throughout the body. Carbon dioxide produced by cells is carried in the blood back to the lungs, where it is exhaled. This cycle of gas exchange between the lungs and bloodstream maintains the balance of oxygen and carbon dioxide in the body.
Smokers have lower concentrations of oxygen in their blood because smoking can damage the lungs and reduce their ability to take in oxygen from the air. This can lead to a decrease in the amount of oxygen that gets into the bloodstream, resulting in lower oxygen levels overall.
Oxygen is not the problem, the issue is body
Blood gets oxygen in the cells. This is part of the body system.
They absorb the oxygen from the cell which gets its oxygen from the blood
the blood is given oxygen as it passes next to the alveoli in the lungs. The process by which the blood gets oxygen is called diffusion
Oxygen is carried in the body by the blood which gets the oxygen in the lungs and this blood is called oxygenated blood
Blood gets oxygen from the lungs. Every time you breath, the oxygen you've inhaled goes into sacs in your lungs called alveoli. The oxygen is diffused into the blood and the blood diffuses carbon dioxide into the alveoli. The carbon dioxide is then exhaled
It gets oxygen to it.

RBC(Red Blood Cell)
Breathing, would supply the blood with oxygen.
Answer:Blood flowing to your lungs is full of carbon dioxide, which gets exchanged in your lungs and the blood flowing out of your lungs is clean/purified with oxygen in it.
The blood gets oxygen from the lungs during the process of respiration. Oxygen is inhaled into the lungs, where it diffuses into the bloodstream via tiny air sacs called alveoli. This oxygenated blood is then pumped by the heart to the rest of the body.
