oxygen is carried in red blood cells
OXYGEN
Oxygen is primarily carried to the cells by hemoglobin in red blood cells, which binds oxygen in the lungs and transports it through the bloodstream. Once it reaches the cells, oxygen is released and utilized for cellular respiration to produce energy. Afterward, carbon dioxide, a waste product of this process, is carried away from the cells back to the lungs for exhalation.
cells use the oxygen to release chemical energy.

Nutrients and oxygen are carried to the cells of the body by the bloodstream. Nutrients are mostly transported by the circulatory system after being absorbed from the digestive system, while oxygen is carried by red blood cells through the process of respiration.
Cellular respiration
Oxygen is carried by the red blood cells. The hemoglobin in the blood mixes with oxygen, and this is transported to other parts of the body.
oxygen is used in respiration which is carried out in all cells .
Oxygen is inhaled into the lungs Oxygen diffuses from the alveoli into the bloodstream Oxygen is carried by red blood cells to body tissues Oxygen is used in the mitochondria for cellular respiration to produce energy
Hemoglobin is a protein that is carried by red blood cells. Homoglobin needs oxygen to be carried by the cells. Without it, the body does not receive enough protein.
