40B - Lab - Exercise #27

Question 1

Arteries

Answer 1

Thick Walls
Carry and move blood AWAY from heart
Carry oxygenated blood

Question 2

What specific arteries carry deoxygenated blood?

Answer 2

Pulmonary Arteries

Question 3

Capillaries

Answer 3

Smallest blood vessels

Materials can leave blood and enter surrounding tissue

Question 4

Veins

Answer 4

Thin Walls
Carry and move blood INTO heart
Carry deoxygenated blood

Question 5

What specific veins carry oxygenated blood?

Answer 5

Pulmonary Veins

Question 6

Order of blood vessels

Answer 6

Artery -> Arteriole -> Capillaries -> Venules -> Vein

Question 7

Myocardium

Answer 7

Cardiac muscle

Question 8

Superior Vena Cava

Answer 8

Returns blood from head, neck, and arms

Question 9

Inferior Vena Cava

Answer 9

Returns blood from the body inferior to the heart

Question 10

Pulmonary Trunk

Answer 10

The only vessel that moves blood from the right ventricle

Question 11

Pulmonary Artery

Answer 11

Carries deoxygenated blood to lungs to get oxygen

Question 12

Pulmonary Veins

Answer 12

Carries oxygenated blood from lungs back to left atrium

Question 13

Auricle

Answer 13

Pouch like extensions. Pulmonary trunk is in between these structures

Question 14

Ligamentum Arteriosum

Answer 14

Blood vessel that is closed in adults

Question 15

Atrium (R/L)

Answer 15

Upper “receiving” chambers of heart

Question 16

Ventricle (R/L)

Answer 16

Lower “pumping” chambers of the heart

Question 17

Tricuspid Valve

Answer 17

Structure between RIGHT atrium and ventricle to prevent blood from flowing backwards

Question 18

Bicuspid Valve

Answer 18

Structure between LEFT atrium and ventricle to prevent blood from flowing backwards

Question 19

Pulmonary Valve

Answer 19

Structure in pulmonary trunk that prevents blood from flowing backwards

Question 20

Aortic Valve

Answer 20

Structure in aorta that prevents blood from flowing backwards

Question 21

Chordae Tendinae

Answer 21

Cords that attach to papillary muscle

Question 22

Interventricular Septum

Answer 22

Separates ventricles

Question 23

Interatrial Septum

Answer 23

Separates Atria

Question 24

Papillary Muscle

Answer 24

Attached heart wall to cordae tendinae

Question 25

Apex

Answer 25

The inferior tip of the heart

Question 26

Coronary Sinus Opening

Answer 26

Blood from the coronary sinus enters the right atrium via this opening

Question 27

Fossa Ovalis

Answer 27

Closed in adults; located within the interatrial septum

Question 28

Coronary Artery (R/L)

Answer 28

Vascularizes the myocardium

Question 29

Coronary Sinus

Answer 29

Collects venous blood from coronary veins and empires into the right atrium through the coronary sinus opening
