During a period of exercise the oxygen demand increased. it was necessary for the blood to deliver 10cm³ of oxygen per minute per 100g of respiring skeletal muscle.
-oxygenated blood carries 20cm³of oxygen per 100cm³ of blood
-80% of the Cardiac output is directed at skeletal muscles when exercising
-skeletal muscles account for 50%of lean body mass
a.Calculate the volume of blood required to deliver sufficient oxygen to the muscles of a person weighing 108kg during exercise?
b.What is the required cardiac output to supply oxygen at this rate?
c.If the person had a heart rate of 193 bpm during exercise what would their stroke volume have been?

Many thanks

In oxygen dissociation curve , the partial pressure of O2 in tissues which is 40mmHg corresponds to the pO2 in tissue capillaries, similarly the pO2 in alveoli is 100mmHg which corresponds to the pO2 in pulmonary capillaries. Why is it so?

I was studying the functions of Smooth endoplasmic reticulum and encountered a function which says 'In the liver the SER contains large amount of Cyrochrome P450 family enzymes that catalyse detoxification of metabolic waste products,drugs and alcohol.'. My question is why does the body need to detoxify drugs when they are taken for medical purposes?
