Document Summary

How the heart works anatomy and function. Right atrium collects blood from vena cava. Blue vessels pulmonary arteries (right) are essentially associated with high co2 mix and low o2 [] Red vessels pulmonary veins (left) have low co2 and high o2 [] Once the blood goes back into the pulmonary veins to the left atrium/left ventricle and then being pumped out through the aorta to the rest of the system. When talking about cardiovascular system, it is stated as the ability of uptake and utilization of oxygen which is important part of the system. 2 ways to look at o2 consumption (vo2) Internal respiration: measure vo2 (oxygen consumption) across capillary beds or particular organ/muscle. Electrocardiogram (ecg) is used to evaluate the normal function in heart. * possible factors that cause cvd external respiration, electrocardiogram, blood pressure. Vo2max and vo2 peak assess external respiration.
