Lab exam 2 - vessels

Question 1

*look at blood vessel slide and label tunica externa, tunica media, tunica intima and lumen

Answer 1

do it now

Question 2

why is it good that arteries have thickened vessel walls

Answer 2

it can withstand high pressure, control blood flow and maintain blood pressure

Question 3

why is it good that veins have thin vessel walls

Answer 3

ensure blood only flows one way

Question 4

does blood pressure increase or decrease in cold temp. why?

Answer 4

increases
cold temp causes blood vessels to narrow. More pressure is needed to push blood through the blood vessels

Question 5

does your blood pressure increase or decrease after exercise, why

Answer 5

immediately after= high bp cause body has not been able to ‘rest’ from the exercise
decreases after 5/10 minutes after exercise=force on the blood vessels is decreased

Question 6

risks of having high bp

Answer 6

stroke, heart attack, anurysm, blocked arteries, kidney problems

Question 7

risk of low bp

Answer 7

fatigue, dizziness, dehydration, bradycardia, heart failure

Question 8

what artery(s) are felt when taking HR on the neck and wrist

Answer 8

neck: corotid
wrist: radial

Question 9

do you expect BP to be higher or lower when taking it on the tibial artery (ankle) as opposed to the brachial artery (arm)

Answer 9

tibial BP will be higher cause it is further from the heart=needs extra resistance to travel

Question 10

Answer 10

ascending aorta
aortic arch
decsending aorta

superior vena cava
right atria

Question 12

Circulatory pathway: Right jugular to left carotid

Answer 12

external/internal jugular vien
brachiocephalic vein
superior vena cava, right atrium right ventricle
pulmonary trunk
pulmonary artery
lungs
pulmonary veins
left atrium
left ventricle
ascending aorta
aortic arch
brachiocephalic trunk
left common carotid

Question 13

name the superficial veins of the arm (6) and locate them on yourself

Answer 13

digital
palmar venous arches
median antebrachial vein
basilic vein
median cubital vein
cephalic vein

Question 14

location of digital veins

Answer 14

drain the fingers and leads to the palmar arches of the hand

Question 15

location of palmar venous arches

Answer 15

drain the hands and fingers and lead to the radial vein, unlar vein, and the median antebrachial vein

Question 16

location of median antebrachial

Answer 16

vein that intertwines with the palmar venous arched and leads to basilic vein

Question 17

location of basilic vein

Answer 17

arises from the median antebrachial vein, intersects with the median cubital vein and continues into the upper arm to the axillary vein

Question 18

location of median cubital vein

Answer 18

located in antecubital region, a frequent site from which to draw blood

Question 19

location of cephalic vein

Answer 19

superficial vessel in the upper arm, leads to axillary vein

Question 20

whats an artery/vien pair that do not share a common name

Answer 20

carotid artery and jugular vein

Question 21

whats an example of an artery that carries deoxygenated blood

Answer 21

pulmonary artery

Question 22

Case study:
a) excessive bleeding, lower leg and foot are pale and cold, no tibial pulse. what arterial injury is this?
b) if the fracture was to the humerus instead what artery would be involved/symptoms would be expected

Answer 22

a) embolus- deep vein thrombosis
b) anterior humeral circumflex artery

Question 23

Case study: post surgery there is a blood clot that blocks the mesentaric artery, what region would become ischemic

Answer 23

blocks small intestine

Question 24

why is an emboli most commonly cause an ishemic event in extremities

Answer 24

they break free and travel

Question 25

what medical condition results from blocked arteries

Answer 25

ischemic stroke

Question 26

what medical condition results from the coronary arteries supplying the heart

Answer 26

heart attack- Athersclerosis

Question 27

Pathway of blood thru vena cava

Answer 27

Both the superior vena cava and inferior vena cava empty blood into the right atrium. Blood flows through the tricuspid valve into the right ventricle. It then flows through the pulmonic valve into the pulmonary artery before being delivered to the lungs

Question 28

Pathway of blood through the four pulmonary veins

Answer 28

pulmonary veins, left atrium, left ventricle, aorta, arteries, arteriorles, capillaries, venules, veins, vena cavae.

Question 29

Orbicularis oris blood supply from heart vessels involved

Answer 29

The arterial blood supply of the orbicularis oris is mostly derived from the superior and inferior labial branches of facial artery, mental and infraorbital branches of maxillary artery and the transverse facial branch of superficial temporal artery.

Question 30

Pathway of blood from heart to diagphragm

Answer 30

The blood supply to the diaphragm is from the superior phrenic, musculophrenic, inferior phrenic, pericardiacophrenic, and lower internal intercostal arteries. The superior phrenic arteries arise from the thoracic aorta

Question 31

Pathway of blood to right bicep brachii

Answer 31

Brachiocephalic trunk
Right subclavian
Right axillary
Right brachial

Question 32

The common carotid artery (3 types) function + where does it go hoe

Answer 32

common carotid artery divides into internal and external carotid arteries. The right common carotid artery arises from the brachiocephalic artery and the left common carotid artery arises directly from the aortic arch.

external carotid artery supplies blood to numerous structures within the face, lower jaw, neck, esophagus, and larynx. These branches include the lingual, facial, occipital, maxillary, and superficial temporal arteries.

internal carotid artery initially forms an expansion known as the carotid sinus, containing the carotid baroreceptors and chemoreceptors. Like their counterparts in the aortic sinuses, the information provided by these receptors is critical to maintaining cardiovascular homeostasis
