Blood vessels

Question 1

General Layers of an artery and vein

Answer 1

Tunica interna
tunica media
tunica externa

Question 2

Layers of the artery

Answer 2

Inside->outside
Lumen is where blood flows
Tunica interna:
1. endothelium
2. basement membrane
3. internal elastic lamina
Tunica Media:
1. smooth muscle
2. external elastic lamina
Tunica externa

Question 3

Layers of the vein

Answer 3

Internal->external
Lumen in the middle w/valve
Tunica interna:
1. endothelium
2. basement membrane
Tunica media:
smooth muscle
Tunica externa:

Question 4

Layers of capillaries

Answer 4

Lumen
endothelium
basement membrane

Question 5

how do lumens of veins and arteries differ

Answer 5

Artery lumen is round
Vein lumen isn’t as round like a long rubber band on a surface

Question 6

how are the arteries and vein joined?

Answer 6

the tunica externa becomes capillaries that join both sides together

Question 7

Does an artery or vein have a valve and where

Answer 7

Vein has a valve in the endothelium

Question 8

does an artery or vein have internal elastic lamina and where

Answer 8

Arteries do, in the tunica interna

Question 9

Does an artery or vein have and external elastic lamina and where

Answer 9

Arteries, last layer of the tunica media

Question 10

arteriole layers

Answer 10

Lumen
endothelium
basement membrane
smooth muscle cells

Question 11

capillary layers

Answer 11

lumen
endothelial cells

Question 12

What blood system is called the blood reservoir

Answer 12

Systemic veins and venules
64% of blood

Question 13

Input to the CV center for blood monitoring

Answer 13

all go to the CV (cardiovascular center of the brain)
Brain centers: cerebral cortex, limbic system, hypothalamus
proprioceptors: monitor joint movements
from baroreceptors: monitor blood pressure
chemoreceptors: monitors blood acidity H+, CO2, O2

Question 14

CV center output

Answer 14

Vagus nerves (parasympathetic): heart decrease rate
Cardiac accelerator nerves (sympathetic): heart: increase rate and contractility
Vasomotor nerves (sympathetic): blood vessels: vasoconstriction

Question 15

what is the right upper body side artery off of the aortic arch called

Answer 15

Brachiocephalic trunk

Question 16

where does the left common carotid branch from

Answer 16

aortic arch

Question 17

do the L and R common carotid arteries branch from similar arteries?

Answer 17

No: L off the aortic arch
R off of the right subclavian

Question 18

Main Arteries of the arm->digits

Answer 18

subclavian
Axillary
(small artery) humeral circumflex
deep brachial
brachial
ulnar collateral
radial+ulnar
Anterior crural interosseous artery is between radial and ulnar deep
Palmar
Digit capillary

Question 19

what arteries branch from brachiocephalic trunk

Answer 19

Right common carotid, right subclavian

Question 20

where is the celiac trunk artery

Answer 20

under the stomach above the pancreas, right of the spleen: feeds hepatic, splenic, gastric arteries

Question 21

What does the superior mesenteric artery feed

Answer 21

The large ascending colon and part of the small intestines through the: Middle colic, right colic, ileocolic, jejunals, ileals,

Question 22

what does inferior mesenteric artery feed?

Answer 22

descending colon and rectum through: left colic, sigmoids, superior rectal

Question 23

aorta ->leg

Answer 23

Aortic arch-> thoracic aorta->abdominal Aorta->R common iliac, Right external iliac (internal iliac goes to the butt), Right femoral, r popliteal, r anterior tibial, r fibular

Question 24

which brachiocephalic has a L and R

Answer 24

Vein

Question 25

how does blood from abdominal organs get to the heart

Answer 25

Splenic vein: Tributaries from stomach pancreas and large intestine
Superior mesenteric vein: tributaries from small intestine, some large intestine, stomach and pancreas
BOTH go to:
Hepatic portal vein->
Liver->
Hepatic veins->
inferior vena cava

Question 26

where does blood flow after right coronary artery

Answer 26

posterior interventricular branch
Marginal branch

Question 27

where does blood flow after the L coronary artery

Answer 27

Anterior interventricular branch
Circumflex branch

Answer 28

Upper right side including head
