Cardiac output how much blood is transported through the system in a minute; how much the heart is beating: heart rate (hr) x stroke volume (sv) Oxygen content: partial pressure oxygen and hemoglobin (changes, oxygen content is different in calgary, and in the top of mt. Everest: if not enough hemoglobin, not enough oxygen carrying capacity. Since 97. 7% are in the hemoglobin, 3. 3% are floating around in the blood stream because hemoglobin has a special on/offload system to be able to deliver that oxygen into the tissues.
