When trying to stop arterial bleeding by applying pressure, why is it necessary to apply pressure between the bleeding part and the heart?
Selected Answer:
Correctc. Because blood flows from the heart through the arteries to the injured part, pressure placed between the heart and the bleeding point cuts off the source of blood flow to that point.
Answers:
a. Because arterial blood pressure changes by alternate contraction and relaxation of the atria, pressure placed between the heart and bleeding point cuts off the source of arterial blood flow to that point.
b. Because venous blood pressure changes by alternate contraction and relaxation of the atria, pressure placed between the heart and bleeding point cuts off the source of venous blood flow to that point.
Correctc. Because blood flows from the heart through the arteries to the injured part, pressure placed between the heart and the bleeding point cuts off the source of blood flow to that point.
d. Because blood pressure is greater in the arteries coming from the heart, pressure placed between the heart and bleeding point reduces pressure, thus cutting off the source of blood flow to that point.
