The diagram below tells you with mitochondria oxygenation pathway in the correlation with tissue hypoxia.
This pathway diagram emphasizes the interconnectedness of the components of tissue oxygenation in the pathway for oxygen from outside air to ultimate consumption within the mitochondria of cells.
Oxygen tension are showed in the diagram with Pi(inspired), PA(alveolar), Pa(arterial), and Pv(venosus). ADP = adenosine diphosphate, ATP =adenosine triphosphate.
