Question 13

blood vessel function

Answer 13

regulate blood flow to tissue
secrete chemicals
control BP

Question 14

Answer 14

feed capillary bed ( give capillary blood)

Question 15

baroreceptor

Answer 15

monitor pressure in AORTA LCC

Question 16

chemical receptor

Answer 16

determine chemical pressure

Question 17

VEIN

Answer 17

outnumber arteries
Less smc
blood reveivoir 70% of total blood in vein / systemic vein
fewer elastic fiber
LARGER LEUMENS

thinner wall

blood highest

Answer 18

highest in systemic arteries
lowest systemic vein

blood flow determined by

Answer 19

magnitude-bp gradient

resistance

velocity - fastest in aorta , slow in capillaries

Answer 22

15 mmHg

Question 23

BP influenced by 3 main factor

Answer 23

peripheral resistance

blood volume

CO =sV xHR

Question 24

hormones control PR

Answer 24

medulla andrella >EPI NEPI >VC ^
ATRIA >ANP VD lower BP
ANGIOTENSINS || > VC ^

Question 25

circulatory shock

Answer 25

severe hypotension due to hypovolemia - loosing blood no oxygen to tissue secrete chemicals

Question 26

CROSS SECTION EXPLAIN

Answer 26

when cross section big it moves slow -capillaries when cross section small it moves fast - arteries
