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
A ? IS A DIRECT CONNECTION BETWEEN AN ARTERIOLE AND A VENULE
ARTERIOVENOUS ANSASTOMOSES
FORCE THAT DRAWS WATER INTO A SOLUTION
OSMOTIC PRESSURE
FENESTRATED CAPILLARIES WOULD BE FOUND IN THE: *intestines, *brain, *skin
INTESTINES
THE ARTERIAL BLOOD PRESSURE REFLECTS WHAT?
HOW MUCH THE ELASTIC ARTERIES CAN BE STRETCHED AND THE BLOOD VOLUME FORCED INTO THEM
BLOOD PRESSURE EQUALS CARDIAC OUTPUT X WHAT?
PERIPHERAL RESISTANCE
COMPARED TO THE WALLS OF ARTERIES, VEINS ARE?
THINNER
LIST THE ORDER OF THE VESSELS THAT PASS THROUGH FROM THE HEART AND BACK
ELASTIC ARTERIES, MUSCULAR ARTERIES, ARTERIOLES, CAPILLARIES, VENULES, MEDIUM VEINS, LARGE VEINS
BLOOD FLOW THROUGH THE CAPILLARY IS REGULATED BY THE
PRECAPILLARY SPHINCTER
THE ACTUAL SITE WHERE EXCHANGE OF SUBSTANCES OCCUR BETWEEN THE BLOOD AND CELLS
TRUE CAPILLARIES
THE RHYTHMIC PRESSURE OSCILLATION THE ACCOMPANIES EACH HEARTBEAT
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
PERICYTES
