VESSELS Flashcards
WHAT IS THE BULKIEST LAYER OF ARTERIES
TUNICA MEDIA
WHAT ARE THE 4 TYPES OF ARTERIES
ELASTIC
MUSCULAR
ARTERIOLES
CAPILLARIES
WHICH ARTERIES ARE ELASTIC ARTERIES
MAJOR BRANCHES OF TEH AORTA MOVING TO THE MEDIUM SIZED ARTERIES
WHAT ARE ELASTIC ARTERIES AKA
CONDUCTING ARTERIES
TRUE OR FALSE - ELASIC ARTERIES CONTAIN LARGE AMOUNTS OF ELASTIN
TRUE
WHICH ARTERIES ACT AS PRESSURE RESEVIOURS THAT DAMPEN THE PULSATILE PRESSURE OF THE HEART
ELASTIC ARTERIES
WHAT IS THE ROLE OF MUSCULAR ARTERIES
DELIVER BLOOD TO SPECIFIC BODY ORGANS
WHAT TYPE OF ARTERY HAS THE THICKEST TUNICA MEDIA RELATIVE TO THEIR LUMEN SIZE
MUSCULAR ARTERIES
WHICH ARTERIES ARE MORE ACTIVE IN VASOCONSTRICTION
MUSCULAR ARTERIES
WHICH ARTERIES ARE LESS CAPABLE OF STRETCHING DUE TO LOWER LEVELS OF ELASTIN
MM ARTERIES
WHICH TYPE OF ARTERIES CONSTRICT OR DILATE IN RESPONSE TO NEURAL, HORMONAL AND CHEMICAL STIMULATION
ARTERIOLES
WHICH TYPE OF ARTERIES ARE REFERRED TO AS RESISTANCE VESSELS
ARTERIOLES
WHAT DO ARTERIOLES CONSTRICT AND DILATE IN RESPONSE TO
THE DEMAND OF THE TISSUES
CAPILLARIES ARE WIDE ENOUGH FOR?
ONE RBC TO PASS THROUGH
WHAT DO CAPILARIES CONSIST OF
A THIN TUNICA INTIMA
WHICH VESSELS SUPPLY O2 AND NUTRIENTS TO TISSUES
CAPILLARIES
WHICH TISSUES DONT HAVE RICH CAPILLARY SUPPLY
CORNEA, CARTILAGE, ACL AND PCL
WHAT DOES MICROCIRCULATION REFER TO
FLOW OF BLOOD FROM AN ARTERIOLE TO A VENULE THROUGH THE CAPILLARY BED
WHAT IS THE ROLE OF CAPILLARY SPHINCTERS
TO ACT AS VALVES AND CONTROL THE FLOW OF BLOOD THROUGH A CAPILLARY BED
WHAT HAPPENS WHEN CAPILLARY SPHINCTERS ARE OPEN
BLOOD THROWS THROUGH CAPILLARIES
WHAT HAPPENS WHEN THE CAPILLARY SPHINCTERS ARE CLOSED
BLOOD FLOWS THROUGH THE VASCULAR SHUNT
CAPILLARIES UNITE TO FORM?
VENULES
WHICH VESSELS ARE EXTREMELY POROUS
POSTCAPILLARY VENULES
WHAT IS THE ROLE OF POST CAPILLARY VENULES IN ACUTE INFLAMMATION
IF YOU TEAR A MM YOU GET AN ACUTE INFLAMMATORY RESPONSE, THE WBC AND PROSTAGLANDINS AND HISTAMINES GO THOUGH THE POROUS VENULES TO GET TO THE TISSUES
