Post by: aloe on Oct 23, 2011
Help please :)

1.  Why do you think body position has an affect on blood pressure & heart rate?  Is this direct or via neutral control?
2.  What causes the sound of the heartbeat?
3.  What are the 3 main waves in an EKG & what do they represent?
4.  How are veins different from arteries in structure & function?
5.  What is the purpose of plotting EKG amplitudes in Einthovens triangle?


Thanx!!
