Which term means low oxygen in tissues?

Explanation:
Low oxygen in tissues is called hypoxia. It means tissues aren’t getting enough oxygen to meet their metabolic needs, which can happen if oxygen content in the blood is low, blood flow is reduced, or cells can’t use oxygen effectively. Hypoxemia refers to low oxygen in the blood, which can contribute to hypoxia but isn’t the same thing. Hypercapnia means high carbon dioxide, not low oxygen, and the right atrium and the aorta are heart/blood vessel structures, not terms describing tissue oxygen status.
