Question

question 190
athero/sclerosis is a type of:
coronary ischemia
arteriosclerosis
lymphangitis
angina pectoris

question 191
the lower chambers of the heart are called the:
bicuspids
pericardia
ventricles
atria

question 192
a patient undergoing testing for emphysema has a \spirometry\ procedure. what is the literal meaning of this term?
breathe/compliance/process
breathe/measure/process
breathe/obstruction/process
lung/measure/process

Explanation:

• Question 190: Atherosclerosis is a form of arteriosclerosis. Arteriosclerosis is a general term for hardening of the arteries. Atherosclerosis specifically involves the buildup of plaque (atheroma) in the arterial walls. Coronary ischemia is a lack of blood flow to the heart muscle (usually due to coronary artery issues like atherosclerosis but is not the same as the condition itself). Lymphangitis is inflammation of lymphatic vessels. Angina pectoris is chest pain (usually due to myocardial ischemia).
• Question 191: The lower chambers of the heart are the ventricles. The right ventricle pumps de - oxygenated blood to the lungs, and the left ventricle pumps oxygenated blood to the rest of the body. Bicuspid is a valve (in the heart, the mitral valve is bicuspid). Pericardia refers to the pericardium (the sac around the heart). Atria are the upper chambers of the heart.
• Question 192: The root “spir -” means breath. The suffix “-metry” means measure. So, spirometry is the process of measuring breath. “Compliance” (in a medical context related to lungs) is about the ability of the lungs to expand, “obstruction” is a blockage, and “lung” would be related to a root like “pneumo -” or “pulmo -”.

Answer:

• Question 190: Arteriosclerosis
• Question 191: ventricles
• Question 192: breath/measure/process
