12 of 65
coagulation
the process of blood turning from liquid into a jelly-like substance used for clotting
13 of 65
fibrinogen
formed in the liver, to help transport blood. during tissue injuries, a fibrin based clot is formed
14 of 65
fibrin
involved in blood clotting, it acts with platelets to form clots.
15 of 65
systemic
a specific location
16 of 65
pulmonary
anything relating to the lungs
17 of 65
myogenic
a specific neutron stimuli rather than a nerve response
18 of 65
pacemaker
an electrical device which is used to generate impulses to control heart rhythm
19 of 65
atria
the two upper chambers of the heart which contract forcing blood through the heart
20 of 65
ventricles
large chambers of the lower heart which receives blood from the atria.
21 of 65
tricuspid valve
located on the right side of the heart, prevents backflow from the right ventricles
22 of 65
bicuspid valve
located on the left side of the heart, it prevents backflow of blood from the left ventricles
23 of 65
superior vena cava
a vein leading into the right atrium containing deoxygenated blood
24 of 65
inferior vena cava
a large vein containing deoxygenated blood from the body into the right atrium
25 of 65
pulmonary artery
artery containing oxygenated blood from the right ventricle to the lungs
26 of 65
semi lunar valve
allows blood to leave the heart through the arteries so no blood flows back
27 of 65
aorta
largest artery leading from the left ventricle to the rest of the body
28 of 65
coronary arteries
arteries which transports oxygenated blood to the heart
29 of 65
cardiac cycle
the heartbeat cycle, consisting of the heart contracting and relaxing
30 of 65
systole
when the heart contracts, pumping blood into the chambers
31 of 65
diastole
when the heart relaxes releasing blood from the chambers and sending it around the body
32 of 65
Sino atrial node
cells located in the right atrium of the heart, producing electrical impulses
33 of 65
atrial ventricular node
connected to the atria and ventricles electrically, opens the coronary sinus
34 of 65
purkyne fibres
located in the ventricle walls
35 of 65
arteries
responsible for the movement of oxygenated blood away from the heart
36 of 65
veins
responsible for movement of deoxygenated blood to the heart
37 of 65
arterioles
small vessels used to increase blood flow through vessels
38 of 65
venules
small blood vessels used to help drain blood from larger vessels
39 of 65
capillaries
a single layer of cells used to supply tissues with oxygen and take waste away
40 of 65
tissue fluid
a liquid used to transport materials from blood cells
41 of 65
lymph
the fluid of the lymphatic system
42 of 65
hydrostatic pressure
pressure of fluid due to the hearts contractions, fluid made to balance equilibrium
43 of 65
osmosis
the movement of fluid through a partially permeable membrane
44 of 65
lymph nodes
carries the lymph fluid and important is important for the immune system
45 of 65
sphygmomanometer
a blood pressure monitor used to measure blood pressure around the body
46 of 65
endothelium
a single layer of cells lining the organs
47 of 65
atheroma
deterioration of the arterial wall due to fatty deposit and scaring
48 of 65
angina
a condition caused by reduction of blood flow to the heart, commonly caused by cholesterol deposits
49 of 65
myocardial infraction
a heart attack caused by part of the heart being starved of oxygen
50 of 65
ventricular fibrillation
when the heart beats too fast and out of rhythm
51 of 65
cardiac arrest
the sudden stop of the heart
52 of 65
angiogram
medical imaging using dye to see the flow of blood through the heart.
53 of 65
angioplasty
repairing the heart surgically by unblocking the blood vessels and placing a stent
54 of 65
coronary bypass
a new heathy vein is grafted to divert blood flow around the blockage
55 of 65
electrocardiogram
ECG, measuring the electrical activity of the heart.
56 of 65
echocardiogram
ECHO, an ultrasound imaging used to monitor the way the heart is beating
57 of 65
hypertension
prolonged high blood pressure
58 of 65
aspirin
a drug used to reduce inflammation, often given during a heart attack

restriction of blood causing parts of the heart to become starved of oxygen
64 of 65
atherosclerosis
a condition where the arteries become hard and narrowed
