The answer is diffusion. The inhaled oxygen passes into the alveoli and then diffuses through the capillaries into the arterial blood. Meanwhile, the waste-rich blood from the veins releases its carbon dioxide into the alveoli. The carbon dioxide follows the same path out of the lungs when you exhale.
no. it gets it from the lungs
No ,it is purplish red .
Through the process of diffusion
it cant.
respiration
photosynthesis
u tell me
Oxidation
This process is Respiration.
Oxidation
Through a process called photosynthesis.
The gas you need to stay alive is Oxygen, you need oxygen to carry vital functions of body, when you inhale oxygen, its goes directly into the lungs and through alveolis, which are present in lungs oxygen get absorbed into blood which is then taken to heart and heart pumps the blood to each and every part and organ of the body, so like this your body works.
