2) You go out for an evening run. Pretty soon you exceed the ability of your circulatory system to supply your leg muscles with sufficient oxygen. What processes are occurring in your muscles? Describe the metabolic pathways and cycles involved.
3) Discuss the reactions by which metabolic CO2 is removed from mammalian tissues by the blood and is given off in the lungs. You may use diagrams to illustrate your discussion.
4) Cary Catastrophe has just had a rather severe mishap with a meat cleaver, and by the time the rescue squad arrives, he has lost a half liter of blood. Describe the systemic regulatory mechanisms which will come into play as his circulatory system tries to compensate for the blood loss.
