2

Blood vessel walls

Tunica externa

tunica media

tunica interna

 

 

3


large/medium

Artery wall features

internal elastic lamina between interna and media

external elastic layer between media and externa

 

4


artery classes


Conducting ateries

distributing arteries

resistance arteries

5


conducting artery


largest

aorta, subclavian, etc...

6


distributing artery


transport blood to organ

renal, hepatic, etc...

7


resistance artery


smaller arteries

arterioles

metarterioles

8


capillaries


continuous

fenestrated

sinusoids

9


continuous capillaries


occur in most tissues

endothelial cells joined by tight junction

intercellular clefts between cells allow for exchange

10


fenestrated capillaires


kidneys, small intestines

endothelial cells contain pores called filtration pores

allow for high rate of exchange

11


sinusoid capillaries


liver, bone and spleen

endothelial cells separated by large gap no basil lamina

allows for formd elemants to enter and exit capillary

12


vein types


postcapillary

muscular veins

medium veins

venous sinuses

large veins

13


Artery function


transfer blood away from heart

14


capillary function


exchange vessels

 

15


vein function


route blood back to heart

16


arterial sense organs

 

monitor blood pressure and chemistry

carotid sinuses

carotid bodies

aortic bodies

17


carotid sinuses

baroreceptors

18


carotid bodies


chemoreceptors

19


aortic bodies


chemoreceptors

20


circulatory system route


heart

ateries

capillaries

veins

heart
