Definition: volume of oxygen utilized by body tissues in order to produce energy per unit time (l/min or ml/kg/min) Determinants of oxygen consumption (vo2: oxygen delivery cardiac output or hr x sv bringing the oxygen, oxygen utilization cellular capabilities of muscle for metabolism how much oxygen the body uses.

Oxidative pathway: ability to make atp to be used in metabolism to create energy, aerobic pathways. During exercise, oxygen demand by muscles is many times greater than at rest. Similar response to heart rate how the oxygen consumption increases. Increased cardiac hemodynamics oxygen with hb in blood interact differently: shunting of blood to skeletal muscles this is why exercise and eating do(cid:374)"t (cid:449)ork together do(cid:374)"t ha(cid:448)e e(cid:374)ough (cid:271)lood to (cid:272)ir(cid:272)ulate for (cid:271)oth of them. Increase oxygen extraction by skeletal muscles they need it for oxidative metabolism.
