Document Summary

Aerobic metabolism (with o2) - the breakdown of nutrients to co2 and water in the presence of o2, large amounts of atp produced. Free fatty acids, glucose + o2 co2 + h2o + energy (heat and work) O2 transported to muscles through the circulatory system. Takes 1-3 minutes to circulatory system to respond to increase metabolic demands, oxygen deficit . Anaerobic metabolism (without o2) - the breakdown of starch or sugar (glucose) molecules to lactic and pyruvic acids in absence of o2, small amounts of atp and lactic acid. Removal of lactic acid requires oxygen (as used called oxygen debt" as muscles will require o2 even after activity ceases) Circulatory system: transport oxygen and nutrients to tissues, remove co2 and waste from tissues, blood/cardiovascular system/blood distribution. Respiratory system: exchange o2 and co2 with external environment. Pulmonary circulation: blood rich in co2 flows from right ventricle via pulmonary artery, lungs, arterioles, capillaries, venules, veins, pulmonary vein, to left atrium.
