Chapter 5 Flashcards
Megaloblastic anemia
Combining form: Megal/o- large
Root: Blast - immature
Suffix: Ic - pertaining to
Definition: A blood disorder characterized by anemia in which the red blood cells are larger than normal
Usually a result of deficiency of folic acid or vitamin B12
Pernicious anemia
Definition: Caused by lack of the intrinsic factor protein (IF) that helps the body absorb vitamin B12 from the gastrointestinal tract, a necessary vitamin for the formation of red blood cells
Sickle cell anemia
Definition: A serious genetic disorder that causes abnormal hemoglobin, causing an abnormal sickle shape in some red blood cells,
This interferes with normal blood flow, resulting in damage to most of the body systems
Thalassemia
Definition: Inherited blood disorder that causes mild or severe anemia due to reduced hemoglobin and fewer red blood cells than normal
Hypertension (HTN)
Prefix: hyper - excessive, higher than normal
Root: tension - pressure
Definition: High blood pressure
The elevation of arterial blood pressure to a level that is likely to cause damage to the cardiovascular system
Primary/idiopathic/essential HTN is consistently elevated blood pressure of unknown cause,
Secondary is caused by another problem, malignant is very high, can be fatal
Hypotension
Prefix: hypo - lower than normal
Root: tension - pressure
Definition: Lower-than-normal arterial blood pressure
Symptoms - dizziness, light-headedness, fainting
Orthostatic/postural hypotension
Definition: Low blood pressure that occurs when standing up
Orthostatic- relating to an upright or standing position
Angiography
Definition: Radiographic (x-ray) study of the blood vessels after the injection of a contrast medium to make these blood vessels visible
Angiogram - the resulting film used to study blood flow in arteries, veins, and blood vessels of the heart
Cardiac catheterization
Definition: Diagnostic and treatment procedure in which a catheter is put into a vein or artery and then guided into the heart
Used to preform angiography and treatment of blocked arteries
Digital subtraction angiography (DSA)
Definition: Uses angiography with computer assistance to clarify the view of the area of interest in the cardiovascular system by “subtracting” the soft tissue and bones from the image
Duplex ultrasound
Definition: A diagnostic procedure to image the sutures of the blood vessels and the flow of blood through these vessels
Combination of diagnostic ultrasound of blood vessels and Doppler ultrasound so show the movement of red blood cells through them
Venography/phlebography
Root: pleb - vein
Combining form: Phleb/o - vein
Suffix: Graphy - process of recording
Definition: A radiographic test that provides an image of specific veins after a contrast dye is injected, producing a venogram
Very accurate test for detecting deep vein thrombosis
Electrocardiography
Root: elect - electric
Combining form: Electr/o - electric
Root: cardi - heart
Combining form: Cardi/o - heart
Suffix: Graphy - process of recording a picture
Definition: Noninvasive process of recording the electrical activity of the myocardium
(Does not require insertion of an instrument or device)
Electrocardiogram
Root: elect - electric
Combining form: Electr/o - electric
Root: cardi - heart
Combining form: Cardi/o - heart
Suffix: Gram - picture of record
Definition: A record of electrical activity of the myocardium
Transcatheter aortic valve replacement (TAVR)
Definition: a relatively new, minimally invasive procedure in which the existing valve is left in place and a fully collapsible replacement valve is delivered to the valve site through a catheter
After it is expanded within the defective valve, it takes over the function
Cardiopulmonary resuscitation (CPR)
Definition: an emergency procedure for life support consisting of artificial respiration and manual external cardiac compression
Compression-only resuscitation can be effective in keeping a patient suffering from cardiac arrest alive until professional responders arrive
Artificial resuscitation is recommended for children, drowning victims, and drug overdoses
Aneurysmectomy
Root: aneurysm -aneurysm
Suffix: ectomy - surgical removal of
Definition: the surgical removal of an aneurysm
Aneurysmorraphy / aneurysmoplasty
Root: aneurysm -aneurysm
Combing Form: aneurysm/o - aneurysm
Suffix: rraphy - surgical suturing
Definition: the surgical suturing of an aneurysm
Aneurysm clipping
Definition: surgical method to isolate an aneurysm from the rest of the circulatory system by placing a small titanium clip along its neck, which remains permanently to prevent blood from flowing into the aneurysm
Arteriectomy
Root: arteri - artery
Suffix: ectomy - surgical removal of
Definition: surgical removal of part of an artery
Hemostasis
Root: hem- blood
Combination form: hem/o - blood
Suffix: stasis - stopping or controlling
Definition: to stop or control bleeding
By the formation of a blood clot by the body, or external application of pressure
Plasmapheresis
Definition: plasma exchange
The removal whole blood from a body and the separation of blood’s cellular elements
Red blood cells and platelets suspended in saline or plasma substitute and returned to circulatory system, cleansing of antibodies
Pulmonary Circulation
Definition: The flow of blood only between the heart and lungs
Pulmonary Arteries
Carry deoxygenated blood out of the right ventricle and into the lungs. This is the only place in the body where deoxygenated blood is carried by arteries instead of veins.
