In your lungs.
may seem surprising that half of the body's cellsare confined to 7 hemoglobin gets out to the tissues of the body, it begins to drop off its oxygen load. The first oxygen molecule is given up reluctantly, but each subsequent one As the hemoglobin picks up oxygen from the lungs and gets more saturated,
The lungs are responsible for picking up oxygen from the air we breathe. Oxygen diffuses across the thin walls of the lung's air sacs (alveoli) into the surrounding blood vessels, where it binds to hemoglobin in red blood cells for transport to tissues throughout the body.
When the blood is flowing back to the heart, the blood has already given off its oxygen to the rest of the body which means it contain less oxygen concentration in the blood. and when blood is flowing from the heart to the rest of the body, the blood contains high level of oxygen because they were being given oxygen by the lungs which passes along the heart and the heart pumps it to the rest of the body.
The circulatory system works with the respiratory systemto get oxygen to the cells of the body. These two systems also work together to get carbon dioxide out of the cells and out of the body.
If by that you mean where they get their own oxygen, then from nowhere because red blood cells do not need oxygen, they perform all reactions anaerobically.If you mean where they get it to give off for the rest of your body, then its from the lungs.
Oxygen is picked up by the blood when it is at the lungs.

Oxygen in the lungs attaches to red blood cells and is carried through the bloodstream to all parts of the body. The oxygen is released from the red blood cells and picked up by tissues that need it for energy production. Carbon dioxide, a waste product, is picked up by the blood and transported back to the lungs to be exhaled.
Your body needs oxygen, which is picked up by the blood from the air in your lungs and then pumped around your body by the heart. If you need more oxygen (by working harder) then your heart has to pump faster.
Hemoglobin, a protein in red blood cells, dissociates from oxygen to release oxygen to tissues in the body. This process occurs in the lungs where oxygen is picked up and then released in areas where it is needed.
alveoli
It circulates the body distributing the oxygen picked up in the gills and collecting carbon di-oxide to exchange in the gills for more oxygen.
The circulatory system transports oxygen from the lungs to the body's cells. Oxygen is picked up by red blood cells in the lungs and carried through blood vessels to tissues and organs where it is exchanged for carbon dioxide. This process is essential for cellular respiration and producing energy in the body.
When you breathe in, your lungs take in oxygen from the air and deliver it to your bloodstream. The oxygen is then carried by red blood cells to your body's tissues, where it is used for energy production. At the same time, carbon dioxide, a waste product of the energy production process, is picked up by the bloodstream and transported back to the lungs to be exhaled out of the body.
The small intestine.
Blood flows through the walls of the lungs to release carbon dioxide and to absorb oxygen for distribution throughout the body.
Yes, blood transports nutrients and oxygen to organs and tissues throughout the body. Nutrients from the food we eat are absorbed into the blood and carried to cells for energy and growth, while oxygen is picked up in the lungs and delivered to tissues to support their function.
