Muscular (Distributing) Arteries and Arterioles

3

Another name of elastic arteries

Conducting Arteries

4

Another name for muscular arteries

Distributing arteries

5

3 types of Capillaries

Continuous Capillaries
Fenestrated Capillaries
Sinusoidal Capillaries

6

5 hormones that play a role in short term regulation of blood pressure

Epinephrine and norepinephrine
Angiotensin II
Atrial natriurectic peptide (ANP)
Antidiuretic Hormone (ADH)

7

main factors influencing blood pressure

cardiac output
peripheral resistance
blood volume

8

vital signs

pulse blood
blood pressure
Respiratory rate
body temperature

9

what does hypertension cause?

heart failure
vascular disease
renal failure
stroke

10

where are chemoreceptors located?

carotid sinus
aortic arch
large arteries of the neck

11

structure of elastic or conducting arteries

thick walls and elastic fibers in all 3 layers

12

structure of muscular or distributing arteries

few elastic fibbers but a thick tunica media with a high percentage of smooth muscle

13

which type of capillary has tight junctions?

continuous capillaries

14

which type of capillary allows large molecules and blood cells to pass through?

sinusoidal capillaries

15

which capillaries contain pores?

fenestrated capillaries

16

which capillaries are only found the liver, bone marrow, and spleen?

sinosoidal capillaries

17

where is blood pressure the highest?

in the aorta

18

the highest pressure found during ventricular systole/contraction

systolic pressure

19

the lower pressure during the phase of ventricular relaxation/diastole

diastolic pressure

20

how to find pulse pressure

subtract diastolic pressure from systolic pressure

21

what is the unit used to measure blood pressure?

mm Hg

22

the pressure that pushes the blood along through the system

mean arterial pressure (MAP)

23

blood vessel that distributes blood to organs

arteries

24

Which artery wall is responsible for vasoconstruction?

tunica media

25

layer of the artery that is composed mainly of elastic and collagen fibers.

tunica externa

26

When an artery or arteriole is damaged, its smooth muscle contracts producing

a vascular spasm

27

which type of artery functions as a pressure reservoir?

Elastic arteries

28

After birth when the umbilical cord is cut what do the umbilical arteries fill with?

Connective tissue

29

the muscular layer of blood vessels

tunica media

30

what do venules unite to form?

veins
