ANATOMY AND PHYSIOLOGY III WITH LAB
AT CHAMBERLAIN COLLEGE OF NURSING
______________________________________________________________________________
_______________
1. Name the heart structure and indicate whether it contains
oxygenated or deoxygenated blood.
A. Right atrium – deoxygenated
B. Left atrium – oxygenated
C. Right ventricle – oxygenated
D. Left ventricle – deoxygenated
Answer: A. Right atrium – deoxygenated
Rationale: The right atrium receives blood from the systemic veins
(superior and inferior vena cava) which is low in oxygen. Its main function is t
o collect deoxygenated blood and direct it into the right ventricle.
,2. Identify the heart structure shown in the diagram.
A. Tricuspid valve
B. Aortic semilunar valve
C. Pulmonary valve
D. Mitral valve
Answer: B. Aortic semilunar valve
Rationale: The aortic semilunar valve is located between the left ventricle a
nd the aorta. It prevents backflow of blood into the ventricle during diastole.
3. Oxygen is carried by _______ cells and binds to proteins call
ed ______ that contain iron.
A. Leukocytes; fibrin
B. Erythrocytes; hemoglobin
C. Platelets; albumin
D. Plasma cells; myoglobin
Answer: B. Erythrocytes; hemoglobin
Rationale: Red blood cells
, (erythrocytes) transport oxygen throughout the body. Hemoglobin, an iron-
containing protein, binds oxygen efficiently and releases it in tissues.
4. Of the formed elements, which cells are responsible for im
mune function, clotting, and gas transport, in that order?
A. Platelets, leukocytes, erythrocytes
B. Erythrocytes, platelets, leukocytes
C. Leukocytes, platelets, erythrocytes
D. Erythrocytes, leukocytes, platelets
Answer: C. Leukocytes, platelets, erythrocytes
Rationale: White blood cells
(leukocytes) defend against infection, platelets are essential for clotting, and
red blood cells
(erythrocytes) transport gases. Each element has a specialized function in th
e blood.
5. What are three major functions of blood?
A. Gas transport, muscle contraction, hormone storage
B. Immune function, temperature regulation, pH regulation
C. Bone formation, nutrient storage, waste removal
D. Digestion, secretion, absorption
Answer: B. Immune function, temperature regulation, pH regulation
Rationale: Blood transports gases, nutrients, and wastes; regulates body te
mperature and pH; supports immune responses; and maintains fluid balance.
These are essential homeostatic roles.
6. A patient has a stroke volume of 70 mL/beat, a heart rate
of 70 beats/min, and other vitals. Calculate cardiac output.
A. 3.5 L/min
B. 4.9 L/min
C. 5.5 L/min
D. 6.0 L/min
