Heart Anatomy/Cell Types
The heart has two ______ that PUMP blood
ventricles
Blood vessels: carry blood AWAY from the heart
artery
Most common type of anemia; not enough hemoglobin
Iron deficiency anemia
The voice box
larynx
A condition in which a person's airways become inflamed, narrow and swell, and produce extra mucus, which makes it difficult to breathe
asthma
Type of cells that carry oxygen- medical term
erythrocyte (RBC)
Smallest blood vessels- deliver oxygen and nutrients to tissues
capillaries
Disease: Heart can’t pump enough blood to meet body’s needs
congestive heart failure
The windpipe
trachea
inflammation of the pleural membrane
pleurisy
Type of cells that assist in clotting- medical term
thrombocyte (platelet)
Pacemaker of the heart- where electrical activity starts
SA Node
Necrosis (death) of heart muscle due to blockage in a coronary artery resulting in formation of a thrombus (clot)
myocardial infarction (heart attack)
the throat
pharynx
Destruction of the alveoli caused by smoking
emphysema
Valve between the right atrium and right ventricle
Tricuspid valve
This wave of the EKG represents depolarization of the ventricle (contraction)
QRS complex
Dilation or saclike formation in a weakened blood vessel; usually caused by atherosclerosis
aneurysm
exchange of oxygen and carbon dioxide occurs here
alveoli
caused by the bacteria Mycobacterium
tuberculosis
The valve between the left atrium and left ventricle
mitral (bicuspid) valve
ST elevation on an EKG indicates
myocardial infarction (heart attack)
Sudden death of brain cells due to a problem with blood supply
stroke
The muscle that separates the thorax from the abdomen and is essential for breathing:
diaphragm
A collapsed or airless state of the lung that results in hypoxia
atalectasis
