method used to divert blood away from the heart and lungs temporarily when surgery of the heart and major vessels are performed. A heart-lung pump collects the blood, replenishes it with oxygen, and returns it to the body.
sinoatrial node (SA)
natural pacemaker of the heart
cardio version
restoring the heart's normal rhythm using electrical shock, may be used when drug therapy is ineffective in treating a cardiac dysrhythmia.
cardiopulmonary resuscitation (CPR)
recommended as an emergency first-aid procedure to reestablish heart and lung action if breathing or heart action has stopped
thrombolytic agent
dissolve the clot
heparin or coumandin
anticoagulant
angioplasty
surgical repair of blood vessels that have become damaged by disease or injury
aortoplasty
surgical repair of the aorta
phleb ectomy
surgical excision of a vein or a segment of it
hemorrhoid ectomy
surgical excision of a hemorrhoid
antiarrhythmic drugs
prevent, alleviate, or correct an abnormal heart rhythm
Digoxin
well-known drug prescribed in the treatment of congestive heart failure and certain arrhythmias
vasodilators
medications that cause dilation of blood vessels
nitroglycerin
a coronary vasodilator
antihypertensives
agents that are used to reduce high blood pressure
diuretics
used and act to reduce the blood volume through greater excretion of water by the kidneys
antilipidemic drugs
anti- = against
-emic = pertaining to blood
prescribed to lower cholesterol levels in the blood, which is generally considered to coincide with a lower incidence of coronary heart disease
primary function of the lymphatic system
collect fluid that escapes from the blood capillaries and return it to circulation
lymph/o
either to the lymphatics or to the fluid lymph, which is the fluid transported by the lymphatic vessels
6 components of the lymphatic system
1. lymph vessels
2. lymph nodes - small knots of tissue at intervals
3. tonsils - masses of lymphatic tissue in the depressions of the mucous membranes of the pharynx (palatine tonsils is tonsill/o vs pharyngeal tonsils are adenoids)
4. thymus
5. spleen
information on lymphatic system
right lymphatic duct receives fluid from the upper right quadrant of the body and empties into the right subclavian vein. thoracic duct, begins with cisterna chyli, collects fluid from the rest of the body and empties it into the left subclavian vein.
lymphatic carcinoma
cancer occurring within the lymphatic system
usually cancer spreads to the lymphatics from another site rather than originating there
lymph oma
lymph/o = lymphatic
-oma = tumor
general term for cancer originating within the lymphatic system
lymph ang itis
angi/o = vessel
-itis = inflammation
an acute or chronic inflammation of lymphatic vessels and can be caused by various microorganisms
lymphangiography
radiography of the lymphatic vessels and nodes after injection of a radiopaque substance has made them visible on x-ray
lymphedema
accumulation of lymph in tissue and the resultant swelling is called lymphedema
lymphangiograms
useful for checking the integrity of the lymphatic system in lymphedema and for investigating the spread of malignant tumors
T/F
lymphatic system were once considered to be glands
FALSE. it was lymph nodes!!!
so the word part aden/o often appears in terms related to lymph nodes.
