oxygenation is the answer i found somewhere else
blood
Deoxygenated blood is not collected anywhere. Blood is a constantly moving stream - it never stops, as the question implies. The oxygen poor blood goes to the lungs, where it turns oxygenated as it takes up oxygen.
Oxygen is absorbed in the blood stream primarily in the lungs through the process of diffusion. When we breathe in, oxygen from the air enters the lungs and diffuses across the alveoli into the capillaries, where it binds to hemoglobin in red blood cells and is transported throughout the body.
Oxygen moving from the bloodstream into a cell is a form of passive transport known as diffusion. This process occurs because oxygen moves from an area of higher concentration (in the blood) to an area of lower concentration (inside the cell) until equilibrium is reached. This mechanism is crucial for cellular respiration, allowing cells to obtain the oxygen needed for energy production.
Oxygen enters the blood stream through the air sacs in you lungs.
In air breathing animals, oxygen enters the blood stream through the alveoli, tiny sacs in the lungs. In water breathing animals oxygen enters the blood stream through the gills.
Oxygen is inhaled to the lungs were a cleaning process occurs. The oxygen is mixed into the blood stream and this is carried by the blood flow around the body. Designated blood returns to the lungs for the cycle to restart
dosent
Oxygen is brought into the blood stream by inhalation. Carbon dioxide moves out of the cells, into the blood, and taken to the lungs to be exhaled. Oxygen in, carbon dioxide out.
monkeys
Blood cells carry the oxygen through the blood stream to the other cells in the body.
