Cardiovascular System

Front 1

Cardiovascular System

Back 1

*Cardiovascular system + lymphatic systems

*Transports nutrients, blood cells, O2, Co2, hormones etc. to the cells of your body

*Composed of a pump (heart) tubes (blood vessels) and fluid blood

Front 2

Right Atrium

Back 2

*Receives low oxygen blood from the body through the superior and inferior vena cava

*Send low oxygen blood to the right ventricle via the tricuspid valve

Front 3

Tricuspid valve

Back 3

*An Atrioventricular valve

*Between right atrium and right ventricle

Front 4

Right ventricle

Back 4

*Receives low oxygen blood from the right atrium

*Sends low oxygen blood to the lungs through the (lungs) pulmonary valve, the pulmonary trunk, and the pulmonary arteries

Front 5

Pulmonary Valve

Back 5

*Between right ventricle and pulmonary trunk

*A "semilunar valve"

Front 6

Left Atrium

Back 6

*Receives oxygen-rich blood from the lungs through the pulmonary veins

*Sends oxygen-rich blood to the left ventricle using the mitral valve

Front 7

Mitral Valve

Back 7

*Between left atrium and left ventricle

*An Atrioventricular valve"

Front 8

Left Ventricle

Back 8

*Receives oxygen-rich blood from the left atrium

*Sends oxygen-rich blood to the body through the aortic valve

*Has the thickest myocardium (heart muscle)

Front 9

Aortic valve

Back 9

*Between left ventricle and aorta

*A "semilunar valve"

Front 10

Interventricular septum

Back 10

*Wall of muscle between the ventricles

*Divides heart into its right and left halves

Front 11

Chordae Tendineae

Back 11

*"Heart Strings"

*Connect the cusps (edges) of the atrioventricular valves to the papillary muscles

*Keeps the valves from inverting!

Front 12

Papillary muscle

Back 12

*Lines the ventricles

*Attaches to the chordae tendineae

Front 13

Superior Vena Cava

Back 13

*Carries low oxygen blood to the heart from the upper body

*Leads into the right atrium

Front 14

Inferior Vena Cava

Back 14

*Carries low oxygen blood to the heart from the lower body

*Enters into the right atrium

Front 15

Pulmonary trunk

Back 15

*Carries low oxygen blood from the right ventricle to the lungs

*Branches into the pulmonary arteries

Front 16

Pulmonary artery

Back 16

*Carries low oxygen blood from the pulmonary trunk to the lungs

*One to the right lung, one to the left

Front 17

Pulmonary vein

Back 17

*Carry high oxygen blood back to the heart from the lungs

Front 18

Aorta

Back 18

Carries high oxygen blood away from the heart to the body

*Has branches that go to different body regions

Front 19

Coronary artery

Back 19

*Carries oxygen-rich blood TOWARD the muscle of the heart itself

*Red wires on model

Front 20

Cardiac Vein

Back 20

*Carries low oxygen blood AWAY from the muscle of the heart itself

Front 21

Veins

Back 21

Carries blood TOWARDS the heart

Front 22

Arteries

Back 22

Carries blood AWAY the heart

Front 23

SA Node

Back 23

*Sinoatrial node

*"Pacemaker"

*Sets the rhythm of the heartbeat

*Ripples in pond

Front 24

AV Node

Back 24

*Atrioventricular node

*Between atria and ventricles

*Slows down electrical impulse

*Sends impulse on the ventricles

Front 25

Bundle of His

Back 25

Transmits electrical signal from AV node to bundle branch

Front 26

Bundle Branch

Back 26

*Splits the Bundle of His into right and left

*Splits electrical signal to right and left ventricles

Front 27

Purkinje Fiber

Back 27

Right and left bundles split into fibers that spread the electrical signal throughout the myocardium of the ventricles
