Cardiovascular Flashcards
Fluid filled sack that surrounds and protects the heart.
pericardium
Muscular layer of the heart
myocardium
Valve between the left atrium and left ventricle.
mitral valve
It drains the blood above the diaphragm
superior vena cava
It drains the blood below diaphragm
inferior vena cava
It drains the blood from the myocardium
coronary sinus
It carries blood away from the heart to lungs
pulmonary arteries
It carries blood from the heart to the rest of the body
systemic circuit
Depolarization of atria
P wave
Depolarization of ventricles
QRS wave
Repolarization of ventricles
T wave
Results from a streptococcal infection in young people; toxin produced by the bacteria can cause rheumatic fever several weeks after the infection that can result in rheumatic endocarditis
rheumatic heart disease
Inflammation of the endocardium; affects the valves more severely than other areas of the endocardium; may lead to scarring, causing stenosed or incompetent valves
Endocarditis
blood group that is a universal donor
O
blood group that is a universal recipient
AB
responsible for the red color of human blood
hemoglobin
It releases histamine, which promotes inflammation, and heparin, which prevents clot formation
basophil
Phagocytizes microorganisms and other substances
neutrophil
It participates in inflammatory response of allergic reactions and asthma; attacks certain worm parasites.
eosinophil
Produces antibodies and other chemicals responsible for destroying microorganisms; contributes to allergic reactions, graft rejection, tumor control, and regulation of immune system.
lymphocytes
Phagocytic cell in the blood; leaves the blood and become a macrophage, which phagocytizes bacteria, dead cells, cell fragments, and other debris within tissues.
