|---|---|---|---|---|---|
| Major structures of the Cardiovascular System | Heart, Blood, Blood Vessels
🗑
|
||||
| Pericardium | Double walled sac that surrounds the heart.
🗑
|
||||
| Epicardium | Outermost layer of the heart wall.
🗑
|
||||
| Myocardium | Middle and thickest layer of the heart wall, contains heart muscle.
🗑
|
||||
| Endocardium | Innermost layer of the heart wall
🗑
|
||||
| Pericardial fluid between heart layers.. | Prevents friction during heart beat.
🗑
|
||||
| Coronary arteries and veins | Provide oxygen rich blood to the myocardium.
🗑
|
||||
| Atria | The two upper chambers of the heart, where blood enters the heart.
🗑
|
||||
| Ventricles | The two lower chambers of the heart, all blood vessels leaving the heart begin here.
🗑
|
||||
| Interatrial Septum | Seperates the two atria from eachother.
🗑
|
||||
| Interventrical Septum | Sperates the two ventricles from eachother.
🗑
|
||||
| Apex | Lower tip of the heart
🗑
|
||||
| Heart Valves | Control flow of blood from one chamber to another.
🗑
|
||||
| Tricuspid Valve | Opening between Right Atria and Right Ventricle
🗑
|
||||
| Pulmonary Semilunar Valves | Opening between right ventricle and pulmonary artery
🗑
|
||||
| Mitral Valve (Bicuspid) | Opening between Left Atrium and Left Ventricle
🗑
|
||||
| Aortic Semilunar Valve | Located between Left Ventricle and Aorta.
🗑
|
||||
| Artery | Carries deoxygenated blood
🗑
|
||||
| Vein | Carries oxygenated blood
🗑

||||
| pic | pic
🗑
|
||||
| The heart follows a sequence to.. | pump blood throughout the body, the contraction and relaxation of the heart has to follow a sequence
🗑
|
||||
| Heart beat | Electrical activity of the heart
🗑
|
||||
| Sinoatrial (SA) Node | *Located in the right atrium *Electrical impulses start a wave of muscle contraction in the heart. *Wave spreads over muscles in bothe atria causing them to contract simutaneously *Contraction forces blood into the ventricles
🗑
|
||||
| Atrioventrucular (AV) Node | Located on the floor of right atrium near the interatrial septum. Transmits electrical impulses to the Bundle of His
🗑
|
||||
| Bundle of His | Located within the interventricular septum Right and left branches of the Bundle of His carry the electrical impulse to the ventricles and the purkinje fibers.
🗑
|
||||
| Purkinje Fibers | Cause the ventricles to contract at the same time forcing blood into the aorta and the pulmonary arteries
🗑
|
||||
| Electrical Waves | activities of the elctrical conduction system can be seen on a cardiac monitor of electrocardiogram
🗑
|
||||
| P Wave | Contraction (electrical simulation) of both atria
🗑
|
||||
| QRS Complex | Contraction of bothe ventricles; atria relax when ventricles contract
🗑
|
||||
| T wave | Relaxation (recovery) of the ventricles
🗑
|
||||
| Lubb sound | caused by tricuspid and mitral valves closing between atria and ventricles
🗑
|
||||
| Dupp sound | Caused by closing of aortic and pulmonary semilunar valves
🗑
