HCB TEST 5 EXAM QUESTIONS AND CORRECT ANSWERS
VERIFIED UPDATED
angina pectoris
pain in the chest when blood supply to the heart is reduced and a portion of the heart is
not receiving enough oxygen
asystole
a condition when the heart ceased generating electrical impulses (FLAT LINE)
cardiac arrest
normal heartbeat and circulation have completely stopped
cardiology
study of the heart
cardiopulmonary resuscitation
actions taken to revive a person by keeping the person's heart and lungs working
coronary arteries
vessels that supply the myocardium
coronary artery disease
diseases that affect the arteries of the heart
deep vein thrombosis
blood clot in a vein, usually a deep vein of the lower limbs
dehydration
fluid output exceeds fluid intake causing a decrease in the amount of fluid in body
tissues
diaphoresis
cool, pale, and moist/sweaty skin; sweating
dysrhythmias
irregular, or absent heart rhythm
edema
swelling from a build up of fluid in the body tissues
,hemorrhage
loss of large amount of blood from the vessels, internal or external
hypo-perfusion
inability of the body to adequately circulate blood to the body's cells to supply them with
oxygen and nutrients (SHOCK)
hypotension
abnormally low pressure of the blood
hypovolemia
Low fluid/blood volume
myocardial infarction
death of the heart muscle due to blockage in an artery (HEART ATTACK)
occlusion
blockage from fatty deposits
palpitations
irregular or rapid heartbeats that feel as a fluttering sensation in the chest
perfusion
supply of oxygen and nutrients to and removal of wastes from the cells and tissues of
the Body as a result of the flow of blood through the capillaries
valve
structure that opens and closes to permit the flow of fluid in only one direction
ventricular fibrillation
condition where the heart's electrical impulses are disorganized, preventing from
contracting normally
what is the blood volume in an average sized adult?
male: 5 to 6 L
female: 4 to 5 L
what are the three functions of blood?
transportation, regulation, protection
What does blood transport?
1. oxygen from the lungs to the cells of the body
2. carbon dioxide from the body cells to the lungs
, 3. nutrients from the GI tract to body cells
4. hormones from endocrine glands to body cells
what does blood regulate?
body temp, pH, fluid volume
which blood cells protects?
white blood cells
what functions do the specific components of blood have?
1. control of bleeding by clotting
2. delivery of oxygen to the cells
3. removal of carbon dioxide from cells
4. removal and delivery of other waste to organs that provide filtration and removal
plasma
contains dissolved nutrients and carries certain crucial proteins such as clotting factors
red blood cells
contain specialized molecules called hemoglobin that bind to oxygen and are
responsible for oxygen delivery to the cells
white blood cells
fight infection by destroying microorganisms and produce antibodies to resist infection
and protect the body from disease
platelets
forms clots, fragments of larger cells that are crucial to the formation of clots; clumping
of platelets is the most rapid and initial response to bleeding
arteries
any blood vessel carrying blood away from the heart
coronary
blood vessel that supply the muscle of the heart
carotid
the large neck arteries, one on each side of the neck, that carry blood from the heart to
the head
aorta
