Cardiovascular system

Postby victor » Sun May 15, 2005 12:32 pm

Hi, I just wanna ask a little bit about cardiovascular system in human body..Is it true that there's a difference when we're checking the hertbeat right in front of the heart and when we're checking the heartbeat in our legs?

The rate should be the same.
Living one day at a time;
Enjoying one moment at a time;
Accepting hardships as the pathway to peace;

Yes, there is a large difference in pressure, which is why nurses and doctors always take blood pressure from the upper arm. But the rate will be the same everywhere in the body.

Kyle is right. Blood presure is the presure blood exercites on the walls of your arteries. Naturally, along the blood circuit this presure is lost. The pulse is actually a shock wave produced when the blood "fired" from the heart hits the blood already in the aorta-therefor it is not lost along the circuit

Oh yes. I thought you were talking a difference about the rate and thats why I asked a difference like what...

you might be talking about the radial femoral pause.
Doctors use this to check if there are any blockages along the way which could help them diagnose a variety of conginital or other cardio vascular problems.

okay, well in that case, there will still be a slight difference, because of the energy lost from the elasticity of the arteries. :lol:

Do you mean a difference between pulse or blood presure?
