Flashcards in cardiovascular system Deck (29):
1

aorta, arch

receives blood pumped from left ventricle

2

pulmonary trunk

receives blood pumped from right ventricle

3

aortic semilunar valve

allows/ direct blood flow from LV into aorta

4

pulmonary semilunar valve

allows/directs blood to flow into pulmonary trunk

5

tricuspid valve

allows/ directs blood to flow from right atrium to right ventricle

6

bicuspid (mitral) valve

allows/ directs blood to flow form left atrium to left ventricle

7

auricles (right and left)

expand to allow increased atrial blood volume

8

ligamentum arteriosum

remnant of fetal ductus arteriosus

9

chord tendineae

hold atrioventricular valves in place

10

papillary muscles

anchor chordae tendineae

11

superior vena cava

returns systemic blood to right atrium

12

inferior vena cava

returns systemic blood to right atrium

13

coronary arteries

serves heart muscle itself

14

cardiac veins

serves heart muscle itself

15

pulmonary veins left and right

carries blood from lungs to LA

16

pulmonary arteries left and right

carries blood form pulmonary trunk to lungs

17

septa. atrial and ventricular

divides heart longitudinally

18

pericardium

surrounds and protects heart

19

fossa ovalis
fetus: foramen ovale

fetal opening between atria

20

sinoatrial node

pacemaker; determines heart rate

21

atrioventricular node

conducts contraction impulses

22

bundle of His, left and right branches

conducts contraction impulses

23

Purkinje fibers

conducts contraction impulses

24

esophagus

food passageway to stomach

25

trachea

air passageway

26

left and right primary bronchi

air passageways to left and right lungs

27

all arteries

carry blood away from the heart

28

all veins

carry blood toward the heart

29

all chambers
RA,RV, LA,LV

pump blood
