Document Summary

Heart rate= 70 bpm; [stroke volume]q = 5 l/min; cao2 cvo2 = 5: 0. 25 l/min, 1. 75 l/min, 2. 5 l/min, 17. 5 l/min, 25 l/min. Vo2 = hr x sv x (cao2 cvo2) In people with lot of areas that lack oxygen get lot of vasal constrictionso much restricted that it becomes hard to pump the blood thru small blood vessels. Pulmonary hyptertension works like a pump n makes your heart pump the blood a lot harder which leads to right ventricular heart failure. ] d)rigid lung pressing on the heart e)all of the above. Emphysema: destroying of alveolar walls (small alveoli walls are destroyed losing surface area making larger alveoli walls) Hence don"t get much surface area for gas exchange to occur. Normally, hypoxia (low oxygen) in the muscle causes vasodialation (vasal dialation of blood vessels) Vasal dialation allows more blood flow and restore oxygen supply (low areas of oxygen open up and lets blood in)
