Question 11

3 Types of Arteries

Answer 11

1) Elastic 2) Muscular (smooth muscle) 3) Arterioles

Question 12

Elastic Arteries

Answer 12

Largest Lots of Elastic fibers( can hold lots of pressure)

Question 13

Muscular arteries

Answer 13

Elastic fibers - more in smooth muscle

Question 14

Arterioles

Answer 14

Smallest have smooth muscle LEAD into capillaries REGULATing blood flow

Question 15

Capillaries

Answer 15

ONE layer: Tunica intima(endothelium and basement membrane 2) Gas and nutrient exchange 3) Form capillary beds

Question 16

Recapillary sphincters

Answer 16

In capillaries can regulate blood

Question 17

Types of Capillaries

Answer 17

1) continuous 2) fenestrated 3) sinusoid

Question 18

Continuous Capillaries

Answer 18

Regular

Question 19

Fenestrated Capillaries

Answer 19

Have little holes and Are in the KIDNEYS

Question 20

Sinusoids Capillaries

Answer 20

Look like been torn apart (big holes) IN LIVER

Question 21

Venules

Answer 21

Small veins connect capillaries to veins 2) Diapedeses (out into tissues)

Question 22

Veins pumped by

Answer 22

Skeletal muscle pumps with the help of valves

Question 23

Blood Pressure

Answer 23

1) Pressure exerted on arterial walls 2) mmHg(measured) 3) Systolic vs diastolic(relax)

Question 24

Systolic

Answer 24

During contraction of heart

Question 25

Diastolic

Answer 25

During relaxing of heart( 2/3 of the time spent)

Question 26

Pulse pressure

Answer 26

Difference Between Systolic and diastolic

Question 27

Hypertension

Answer 27

140 /90 starts

Question 28

Prehypertension

Answer 28

120-140 / 80-90

Question 29

Mean arterial pressure

Answer 29

93 at rest (normal)

Question 30

Liver circulation

Answer 30

AKA hepatic portal circulation; when most nutrients are absorbed in the digestive track they are sent to the liver

Portal Triad

Answer 31

1) Hepatic portal vein 2) Hepatic artery 3) Bile Duck

Question 32

Part of liver circulation (4)

Answer 32

1) Portal triad 2) Central Vein 3) Sinusoid(leaky veins) 4) Kupffer cells

Question 33

Kupffer cells

Answer 33

With in sinusoids in liver; Phagocytic

Question 34

Central vein

Answer 34

Drains blood from liver

Question 35

Hepatic portal vein

Answer 35

Blood from GI -> Liver

Question 36

Hepatic artery

Answer 36

O2 blood to liver
