BZ 101 EXAM 2 QUESTIONS AND ANSWERS
Simple squamous epithelium has
A) a single layer of cube-shaped cells.
B) a single layer of column-shaped cells.
C) a single layer of flattened cells.
D) many layers of flattened cells.
E) many layers of cube-shaped cells. - CORRECT ANSWER✅✅C) a single layer of flattened cells.
(Simple means that there is a single layer. Squamous means that the cells are flat.)
The outer sac that encloses the heart and provides lubrication is the:
A) myocardium.
B) endocardium.
C) ectocardium.
D) pericardium.
E) coronary capsule. - CORRECT ANSWER✅✅D) pericardium.
(The membrane that surrounds the heart is called the pericardium. The myocardium is the muscle tissue
of the heart.)
Blood richest in oxygen is found in the
A) inferior vena cava.
B) superior vena cava.
C) pulmonary arteries.
D) pulmonary veins.
E) systemic capillaries. - CORRECT ANSWER✅✅D) pulmonary veins.
(The pulmonary veins have just picked up oxygen from the lungs so they contain the highest
concentration of oxygen.)
Which antibody class is most responsible for the allergic reaction?
A) IgA

B) glucose.
C) urea.
D) oxygen.
E) glycogen. - CORRECT ANSWER✅✅E) glycogen.
(All of these are components of the blood, except for glycogen. Glycogen is the storage form of glucose
found within animal cells.)
Blood rich in oxygen enters the heart at the
A) left atrium.
B) left ventricle.
C) right atrium.
D) right ventricle.
E) pulmonary arteries. - CORRECT ANSWER✅✅E) pulmonary arteries.
(The pulmonary vein brings oxygenated blood from the lungs to the left atrium.)
In order to decrease the effects of inflammation, you would take what type of medication?
A) antihistamine
B) vaccine
C) interferon
D) immunoglobulin
E) thromboplastin activator - CORRECT ANSWER✅✅A) antihistamine
