SYSTEM OF TINY BLOOD VESSELS THAT NOURISH THE MORE EXTERNAL SURFACES OF LARGER BLOOD VESSELS
|
VASA VASORUM
|
|
|
*LEFT SUBCLAVIAN ARTERY, * SUPERIOR VENA CAVA, *CAPILLARY: which of these has the most elastic fibers?
|
SUPERIOR VENA CAVA
|
|
|
CALLED RESISTANCE VESSELS BECAUSE THE CHANGESIN THEIR DIAMETER AFFECT THE AMOUNT OF FORCE REQUIRE TO PUSH BLOOD AROUND THE CARDIOVASCULAR SYSTEM
|
ARTERIOLES
|
|
|
BLOOD PRESSURE IS THE ?
|
FORCE EXERTED BY THE BLOOD ON THE WALLS OF THE BLOOD VESSELS
|
|
|
WHY ARE VEINS CALLED CAPACITANCE VESSELS?
|
THEY HOLD 65% OF THE BLOOD VOLUME THAT CAN BE DRAWN IN TIMES OF NEED
|
|
|
WHY DOES OUR BLOOD PRESSURE GO UP WITH AN INCREASE IN OUR SIZE?
|
BECAUSE THE BLOOD VESSELS BECOME LONGER, HENCE MORE RESISTANCE

|
|
|
THE ARTERIAL BLOOD PRESSURE REFLECTS WHAT?

PERIPHERAL RESISTANCE
|
|
|
COMPARED TO THE WALLS OF ARTERIES, VEINS ARE?
|
THINNER
|
|
|

PULSE
|
|
|
ROUTES IN CAPILLARY WALL INCLUDE:
|
CHANNELS, INTERCELLULAR CLEFTS, PORES, AND THROUGH THE ENDOTHELIAL MEMBRANE
|
|
|
OPPOSITION TO FLOW AND A MEASURE OF THE AMOUNT OF FRICTION BLOOD ENCOUNTERS AS IT PASSES THROUGH THE VESSELS
|
RESISTANCE
|
|
|
PROCESS THAT MOVES MATERIALS ACROSS A TYPICAL CAPILLARY WALL AS A RESULT OF OSMOSIS
|
REABSORPTION
|
|
|
SMOOTH MUSCLE LIKE CELLS THAT STABILIZE CAPILLARY WALLS
