Q. Regarding haemodynamic principles, which statement is FALSE? (Solved)
1. viscosity of blood with haematocrit of 40 is three times that of water
2. ‘arterial’ blood volume is 10-15% total volume
3. ‘elastance’ measures a vessel’s stiffness or recoil
4. aging causes increased elastance and therefore decrease in resting (unstressed) arterial volume
5. an increase in total peripheral resistance leads to increased arterial volume and BP
- d. aging causes increased elastance and therefore decrease in resting (unstressed) arterial volume
