Q

WHY DOES BLOOD VISCOSITY EFFECT PERIPHERAL RESISTANCE?

A

THE THICKER THE BLOOD THE GREATER THE RESISTANCE AND LESS BLOOD FLOW.
THE THINNER THE BLOOD THE LOWER THE RESISTANCE AND MORE BLOOD FLOW

Q

WHY DOES VESSEL LENGTH EFFECT PERIPHERAL RESISTANCE

A

PRESSURE AND LOW INCREASE WITH DISTANCE - THE LONGER THE VESSEL THE MORE RESISTANCE AND FRICTION AS THE BLOOD IS IN CONTACT WITH VESSELL WALL FOR A LONGER DURATION

Q

WHY DOES VESSEL RADIUS AFFECT PERIPHERAL RESISTANCE

A

WHEN VESSELLS DIALATE THE BLOOD PRESSURE BECOMES WEAKER - WHEN VESSELS CONSTRICT THE PRESSURE BECOMES GREATER
