Cardiovascular System
|
*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 |
|
Right Atrium
|
*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 |
|
Tricuspid valve
|
*An Atrioventricular valve
*Between right atrium and right ventricle |
|
Right ventricle
|
*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 |
|
Pulmonary Valve
|
*Between right ventricle and pulmonary trunk
*A "semilunar valve" |
|
Left Atrium
|
*Receives oxygen-rich blood from the lungs through the pulmonary veins
*Sends oxygen-rich blood to the left ventricle using the mitral valve |
|
Mitral Valve
|
*Between left atrium and left ventricle
*An Atrioventricular valve" |
|
Left Ventricle
|
*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) |
|
Aortic valve
|
*Between left ventricle and aorta
*A "semilunar valve" |
|
Interventricular septum
|
*Wall of muscle between the ventricles
*Divides heart into its right and left halves |
|
Chordae Tendineae
|
*"Heart Strings"
*Connect the cusps (edges) of the atrioventricular valves to the papillary muscles *Keeps the valves from inverting! |
|
Papillary muscle
|
*Lines the ventricles
*Attaches to the chordae tendineae |
|
Superior Vena Cava
|
*Carries low oxygen blood to the heart from the upper body
*Leads into the right atrium |
|
Inferior Vena Cava
|
*Carries low oxygen blood to the heart from the lower body
*Enters into the right atrium |
|
Pulmonary trunk
|
*Carries low oxygen blood from the right ventricle to the lungs
*Branches into the pulmonary arteries |
|
Pulmonary artery
|
*Carries low oxygen blood from the pulmonary trunk to the lungs
*One to the right lung, one to the left |
|
Pulmonary vein
|
*Carry high oxygen blood back to the heart from the lungs
|
|
Aorta
|
Carries high oxygen blood away from the heart to the body
*Has branches that go to different body regions |
|
Coronary artery
|
*Carries oxygen-rich blood TOWARD the muscle of the heart itself
*Red wires on model |
|
Cardiac Vein
|
*Carries low oxygen blood AWAY from the muscle of the heart itself
|
|
Veins
|
Carries blood TOWARDS the heart
|
|
Arteries
|
Carries blood AWAY the heart
|
|
SA Node
|
*Sinoatrial node
*"Pacemaker" *Sets the rhythm of the heartbeat *Ripples in pond |
|
AV Node
|
*Atrioventricular node
*Between atria and ventricles *Slows down electrical impulse *Sends impulse on the ventricles |
|
Bundle of His
|
Transmits electrical signal from AV node to bundle branch
|
|
Bundle Branch
|
*Splits the Bundle of His into right and left
*Splits electrical signal to right and left ventricles |
|
Purkinje Fiber
|
Right and left bundles split into fibers that spread the electrical signal throughout the myocardium of the ventricles
|
