|
Aorta |
Largest artery in the body |
|
|
Apex of the heart |
Lower tip of the heart |
|
|
Arteriole |
Small artery |
|
|
Artery |
Largest type of blood vessel carries blood away from the heart to all parts of the body. Notice that artery and Away begin with an "A" |
|
|
Atrioventricular bundle ( bundle of HIS) |
Specialized muscle fibers connecting the atria with verticals and transmitting electrical impulses between them. His is pronounced "hiss" |
|
|
Atrium |
One of two upper chambers of the heart |
|
|
Atrioventricular node (AV node) |
Specialized tissue in the wall between the atria. Electrical impulses pass from the pacemaker through the AV node and atrioventricular bundle or bundle of His toward the verticals |
|
|
Capillary |
Smallest blood vessel. Material passed to and from the bloodstream through the thin capillary walls |
|
|
Carbon dioxide |
Gas (waste) for lease by body cells transported via veins to the heart and then to the lungs for exhalation |
|
|
Coronary arteries |
Blood vessels that Branch from the aorta and carry oxygen-rich blood to the heart muscle |
|
|
Deoxygenated blood |
Blood that is oxygen poor |
|
|
Electrocardiogram |
Record of electricity flowing through the heart. The electricity is represented by waves or deflections called P, QRS, or T |
|
|
Distole |
Relaxation phase of the heartbeat |
|
|
Endocardium |
Inner lining of the heart |
|
|
Endothelium |
Innermost lining of blood vessels |
|
|
Mitral valve |
Valve between the left atrium and the left ventricle; bicuspid valve |
|
|
Murmur |
Abnormal swishing sound caused by improper closure of the heart valves |
|
|
Myocardium |
Muscular middle layer of the heart |
|
|
Normal sinus rhythm |
Heart rhythm originating in the sinoatrial node with a rate and patients at rest of 60 to 100 beats per minute |
|
|
Oxygen |
Gas that enters the blood through the lungs and travels to the heart to be pumped via arteries to all body cells |
|
|
Pacemaker |
Specialized nervous tissue in the right atrium that begins the heartbeat. An artificial cardiac pacemaker is an electronic apparatus implanted in the chest to stimulate heart muscle that is weak and not functioning. |
|
|
Pericardium |
Double-layered membrane surrounding the heart |
|
|
Pulmonary artery |
Artery carrying oxygen-poor blood from the heart to the lungs |
|
|
Pulmonary circulation |
Flow of blood from the heart to the lungs and back to the heart |
|
|
Pulmonary valve |
Well positioned between the right vertical in the pulmonary artery |
|
|
Pulmonary vein |
One of two pairs of vessels carrying oxygenated blood from the lungs to the left atrium of the heart |
|
|
Pulse |
Beat of the heart as felt through the walls of the arteries |
|
|
Septum |
Partition or wall dividing a cavity such as the right and left atria and right and left ventricles |
|
|
Sinoatrial node (SA node) |
Pacemaker of the heart |
|
|
Sphygmomanometer |
Instrument to measure blood pressure |
|
|
Systemic circulation |
Flow of blood from body tissue to the heart and then from the heart back to the body tissues |
|
|
Systole |
Contraction phase of the heart |
|
|
Tricuspid valve |
Located between the right atrium and the the right ventricle it has three leaflets, or cusps. |
|
|
Valve |
Structure and veins are in the heart that temporarily closes an opening so blood flows in Only One Direction |
|
|
Vein |
Thin-walled vessels that carries blood from the body tissues and lungs back to the heart. veins contain valves to prevent backflow of blood |
|
|
Vena cava |
Largest vein in the body. The superior and inferior venae cavae return blood to the right atrium of the heart. |
|
|
Ventricle |
One of two lower chambers of the heart |
|
|
Venule |
Small vein. |
