Back 3

increases significantly

Front 4

4. Which of the following is true regarding the distribution of blood flow and venous return? (30% of the total blood volume is in the venous system, blood is shunted to vital organs during cardiac failure, circ funct & press can be maintained with a loss of 40% of the blood vol, all of the above)
