Chapter-9 The Cardiovascular System- Cardiology Flashcards
valvul/o
roots
Def: valve
Ex: valvulotomy, valvulitis
Notes: The heart has four valves: two atrioventricular valves and two valves between the ventricles and arteries. The purpose of heart valves is to prevent blood from flowing backward.
atri/o
roots
Def: atrium (upper chamber)
Ex: atrium, atrial fibrillation
Notes: The atrium is the upper portion of each side of the heart. The term comes from Roman architecture, where it referred to the large open area that was characteristic of most Roman houses; typically, all the other rooms of the house would branch off from this center space. Even today, a large central area in a building is often called its atrium.
sept/o
roots
Def: septum (plural: septa)
Ex: atrial septal defect, septoplasty
Notes: Septum comes from a Latin word meaning “partition” or “dividing structure” and can refer to any wall dividing two cavities. There are numerous septa throughout the body, including between the two sides of the heart. The easiest to find is the nasal septum. If you place an index finger in each nostril and try to make them touch, what you are feeling is the nasal septum. If you find that your nasal septum leans to one side, you have a deviated septum.
ventricul/o
roots
Def: ventricle (lower chamber)
Ex: ventriculotomy
Notes: The ventricle is the lower portion of each side of the heart. The word is a combination of venter (stomach) plus the diminutive suffix -icle, and means “little stomach.”
cardi/o
roots
Def: heart
Ex: cardiology, cardiac arrest, myocarditis
Notes: The root cardio can be tricky because it ends in the double vowel io. You expect the o to go away sometimes, but when a suffix beginning with an i is added to this root, not just the o, but also an i disappears as well. For example: myo (muscle) + cardio (heart) + itis (inflammation) = myocard-I-itis.
coron/o
roots
Def: heart
Ex: coronary artery, coronary thrombosis
Notes: the term corona literally means “crown” and refers to the way the blood vessels that supply the heart descend and support the heart like a crown. The term coronary is used in medical language to refer specifically to the heart’s blood supply.
angi/o
roots
Def: vessel
Ex angioplasty angiogram
Notes: All these roots come form words meaning “jar” or “pitcher.” Angio comes from Greek, and vaso and vasculo come from Latin. Although blood vessels don’t look like jars, they do hold a lot of liquid- almost 6 quarts in the average man and almost 4 quarts in the average woman.
vas/o
roots
Def: vessel
Ex: vasodilator
vascul/o
roots
Def: vessel
Ex: vasculitis
aort/o
roots
Def: aorta
Ex: aortitis, aortolith
Notes: The aorta is the main artery leaving the heart and distributing oxygenated blood throughout the body. Its name means “to rise up” and refers to the fact that as the aorta leaves the heart, it rises up briefly and branches off into the arteries that supply the upper body before making what is called the arch of the aorta and descending into the lower body.
arteri/o
roots
Def: artery
Ex: arteriosclerosis, endarterectomy
Notes: Arteries are the large blood vessels that carry oxygenated blood from heart to body tissue. It’s funny that the word artery is actually a Greek word for “trachea” or “windpipe,” a reference to the fact that some of the body’s arteries are so large that early students of anatomy thought they carried air.
ather/o
roots
Def: fatty plaque
Ex: atherosclerosis
Notes: This root comes from Greek, for “gruel” or “porridge.” Be careful: This root is easily confused with arterio, especially in the words arteriosclerosis and atherosclerosis. There’s a reason for the confusion: atherosclerosis is actually a form of arterosclerosis. Arterioclerosis means “hardening of an artery” and atherosclerosis means “hardening of an artery due specifically to buildup of fatty plaque.”
phleb/o
roots
Def: vein
Ex: phlebotomy
ven/o
roots
Def: ven/o
Ex: venospasm
