150 Questions — Review Set
Question 1
Blood is classified as which type of tissue?
□ A. Epithelial
✓ B. Connective
□ C. Muscle
□ D. Nervous
Correct Answer: B. Connective
Feedback: Blood is a specialized connective tissue composed of cells suspended in a liquid extracellular
matrix called plasma.
Question 2
What is the normal pH range of human blood?
□ A. 7.00-7.25
✓ B. 7.35-7.45
□ C. 7.50-7.65
□ D. 6.80-7.00
Correct Answer: B. 7.35-7.45
Feedback: Human blood is slightly alkaline with a normal pH range of 7.35 to 7.45, maintained by buffer
systems.
Question 3
Which of the following is NOT a function of blood?
□ A. Transportation of oxygen
□ B. Regulation of body temperature
□ C. Production of antibodies
✓ D. Synthesis of vitamin D
Correct Answer: D. Synthesis of vitamin D
Feedback: While blood transports many substances, vitamin D synthesis occurs primarily in the skin via
sunlight exposure.
Question 4
,What is the average blood volume in an adult male?
□ A. 3-4 liters
□ B. 4-5 liters
✓ C. 5-6 liters
□ D. 6-7 liters
Correct Answer: C. 5-6 liters
Feedback: The average adult male has approximately 5-6 liters of blood, while females average 4-5 liters.
Question 5
The liquid matrix of blood is called:
□ A. Serum
✓ B. Plasma
□ C. Interstitial fluid
□ D. Lymph
Correct Answer: B. Plasma
Feedback: Plasma is the liquid portion of blood, making up about 55% of total blood volume.
Question 6
Which plasma protein is most abundant?
□ A. Globulins
□ B. Fibrinogen
✓ C. Albumin
□ D. Prothrombin
Correct Answer: C. Albumin
Feedback: Albumin constitutes about 60% of plasma proteins and is crucial for maintaining osmotic pressure.
Question 7
Serum differs from plasma in that serum lacks:
□ A. Water
□ B. Electrolytes
✓ C. Clotting factors
□ D. Glucose
Correct Answer: C. Clotting factors
Feedback: Serum is plasma from which fibrinogen and other clotting factors have been removed.
,Question 8
Which formed element is the most numerous in blood?
□ A. Leukocytes
□ B. Thrombocytes
✓ C. Erythrocytes
□ D. Neutrophils
Correct Answer: C. Erythrocytes
Feedback: Red blood cells (erythrocytes) are the most abundant formed elements, numbering about 4.5-5.5
million per microliter.
Question 9
What is the primary function of erythrocytes?
□ A. Phagocytosis
□ B. Blood clotting
✓ C. Oxygen transport
□ D. Antibody production
Correct Answer: C. Oxygen transport
Feedback: Erythrocytes contain hemoglobin, which binds and transports oxygen from the lungs to tissues.
Question 10
Hemoglobin is composed of which protein chains?
✓ A. Two alpha and two beta
□ B. Four alpha
□ C. Two gamma and two delta
□ D. One alpha and three beta
Correct Answer: A. Two alpha and two beta
Feedback: Hemoglobin is a tetramer consisting of two alpha and two beta globin chains, each with a heme
group.
Question 11
The lifespan of a typical erythrocyte is approximately:
□ A. 30 days
□ B. 60 days
✓ C. 120 days
□ D. 180 days
, Correct Answer: C. 120 days
Feedback: Red blood cells circulate for about 120 days before being removed by macrophages in the spleen
and liver.
Question 12
Erythropoiesis is stimulated by which hormone?
□ A. Thyroxine
✓ B. Erythropoietin
□ C. Cortisol
□ D. Insulin
Correct Answer: B. Erythropoietin
Feedback: Erythropoietin (EPO), produced mainly by the kidneys, stimulates red blood cell production in bone
marrow.
Question 13
Which organ is primarily responsible for erythropoietin production?
□ A. Liver
□ B. Spleen
✓ C. Kidney
□ D. Bone marrow
Correct Answer: C. Kidney
Feedback: The kidneys detect low oxygen levels and release erythropoietin to stimulate erythropoiesis.
Question 14
Low oxygen levels in the blood stimulate the release of:
□ A. Heparin
✓ B. Erythropoietin
□ C. Thrombopoietin
□ D. Histamine
Correct Answer: B. Erythropoietin
Feedback: Hypoxia triggers the kidneys to increase erythropoietin secretion, boosting red blood cell
production.
Question 15
What is the oxygen-carrying capacity of blood directly dependent upon?
□ A. Leukocyte count
