Endocardium
inner lining of he heart; lines chambers & valves within the heart
Myocardium
muscle layer of the heart
Pericardium
membrane surrounding the heart; made of visceral pericardium & parietal pericardium
Aorta
largest artery in the body
Aortic valve
valve between the left ventricle and aorta
Apex
pointed end of the heart
Artery
largest vessel in the body; carries blood away from the heart
Atrioventricular bundle
specialized muscle fibers in the interventricular septum; carry electrical impulses to ventricles (bundle of His)
Atrioventricular node (AV node)
specialized tissue in the interatrial septum; carries impulses from the SA node to AV node
Atrioventricular valves (AV valves)
valves between atria and ventricles
Atrium (plural: atria)
two upper heart chambers
Base
cranial portion of the heart
Bicuspid valve
valve between left atrium and left ventricle; mitral valve or left AV valve
Capillaries
smallest blood vessels
Carbon dioxide
gas released by tissue cells and transported to the heart and lungs for exhalation
Coronary arteries
supply blood and oxygen to the myocardium
Deoxygenated blood
oxygen poor blood
Diastole
relaxation phase of the heartbeat
Endothelium
epithelial cells lining the heart cavities and vessls
Oxygen
gas that enters the blood through the lungs and travels to the heart to be pumped to the rest of the body
Oxygenated blood
oxygen rich blood
Pulmonary artery
artery that carries deoxygenated 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
valve between the right ventricle and pulmonary artery
Pulmonary veins
veins that carry oxygenated blood from the lungs to the heart
Pulse
heartbeat felt through the walls of the arteries
Semilunar valves
valves between the entrances of the aorta and pulmonary artery (shaped like half moon)
Septum
partition
Sinoatrial node
pacemaker of the heart
Sinus rhythm
normal heart rhythm
Systemic circulation
flow of blood from the body cells to the heart and back out to the body cells
Systole
contraction phase of the heart
Valves
structures in veins and in the heart that temporarily close an opening so that blood can flow in one direction
Vein
thin walled vessel that carries blood towards the heart
Vena cavae (singular: vena cava)
larges vein in the body
Ventricles
two lower chambers of the heart
Aneurysm
sac (dilation) formed by weakening of a blood vessel
can lead to hemorrhage and stroke
Arrhythmia
abnormal heart rhythm
Asystole
without contraction; lack of heart activity
Atherosclerosis
hardening of arteries due to plaque buildup
Ausculatation
listening w/ a stethoscope to sounds within the body
Cardiac hypertrophy
enlargement of the heart due to increased cell size
Cardiac tamponade
compression of heart due to fluid or blood in the pericardial sac
Congenital heart disease (CHD)
abnormalities of the heart at birth
Congestive heart failure (CHF)
heart is unable to pump its required amount of blood
Capillary refill time (CRT)
time it takes for the mucous membranes to return to a normal pink color after applying finger pressure
Defibrillation
use of electrical shock to restore normal heart rhythm
Echocardiogram (ECHO)
high-frequency sound waves and echoes that produce and image of the heart
Embolism
blockage of a vessel by a clot or foreign material
Embolus (plural: emboli)
detached, moving clot
Fibrillation
rapid, random, and irregular contractions of the heart
Flutter
rapid but regular contractions of the atria and ventricles
Heartworm
infestation of the parasite Dirofilaria immitis in the right ventricle and pulmonary arteries
transmitted after a blood meal from a mosquito
Hypertension
increased blood pressure
Hypotension
decreased blood pressure
Hypoxia
decreased oxygen to tissues
Infarction
area of dead tissue
Ischemia
lack of blood flow to tissues
Mitral valve prolapse (MVP)
displacement of the bicuspid valve leading to incomplete closure of the valve during ventricular contraction
Murmur
extra heart sound
Occlusion
blockage; obstruction or closure of body passage
Patent
open; unobstructed (used for vessels and catheters)
Patent ductus arteriosus (PDA)
condition in which the small duct between the aorta and pulmonary artery, which normally closes after birth, remains open
Perfusion (tissue perfusion)
passage of fluid through the blood vessels of a specific organ; blood flow through the tissue
Pericardial effusion
escape of fluid into the pericardial sac leading to cardiac tamponade
Premature ventricular contraction (PVC or VPC)
ventricles are triggered to contract by the Purkinje fibers rather that the SA node
Shock
inadequate tissue perfusion; blood pools in the capillaries to increase the blood volume of the pt, which decreases its flow to vital organs
Sphygmomanometer
instrument that measures arterial blood pressure
Stent
small expander inserted into tubular structures such as vessels to provide support and prevent collapse
Tetralogy of Fallot
congenital malformation of the heart that combines four structural defects; pulmonary artery stenosis, ventricular septal defect, aortic right shift, and right ventricular hypertrophy
Thrill
vibration felt on palpation of the chest; usually caused by turbulence in the heart
Thrombus (plural: thrombi)
stationary clot attached to the wall of a vessel
Ventricular septal defect (VSD)
small hole(s) in the interventricular septum; causes shunting of the blood and therefore deoxygenated blood is pumped to the rest of the body
Vasoconstriction
narrowing of a vessel
Vasodilation
expansion of a vessel
