BLOOD AND HEMATOLOGY (Questions 1–18)
1. Blood is classified as which type of tissue?
A) Epithelial tissue
B) Connective tissue
C) Muscle tissue
D) Nervous tissue
Correct Answer: B) Connective tissue – Blood consists of cells (formed
elements) suspended in a liquid extracellular matrix called plasma. Like other
connective tissues, blood develops from mesenchyme and connects body systems
together.
2. Which of the following is NOT a function of blood?
, A) Transport of oxygen and nutrients
B) Regulation of body temperature
C) Production of hormones
D) Protection against pathogens
Correct Answer: C) Production of hormones – Blood transports hormones
produced by endocrine glands but does not produce hormones itself. Blood
functions include transportation, regulation (pH, temperature, fluid balance), and
protection (immunity, clotting).
3. What is the normal pH range of human blood?
A) 7.0 – 7.2
B) 7.25 – 7.35
C) 7.35 – 7.45
D) 7.5 – 7.6
Correct Answer: C) 7.35 – 7.45 – The normal pH of arterial blood is tightly
regulated between 7.35 and 7.45, with an average of 7.4.
4. Which formed element is responsible for transporting oxygen and contains
the protein hemoglobin?
A) Leukocytes
B) Thrombocytes
C) Erythrocytes
D) Plasma proteins
Correct Answer: C) Erythrocytes – Red blood cells are the primary carriers of
oxygen because they contain hemoglobin, which binds to oxygen molecules in the
lungs.
5. The percentage of blood volume occupied by erythrocytes is called:
A) Hematocrit
B) Hemoglobin concentration
C) Blood viscosity
, D) Plasma volume
Correct Answer: A) Hematocrit
6. Which plasma protein is primarily responsible for maintaining the colloid
osmotic pressure of the blood?
A) Albumin
B) Globulin
C) Fibrinogen
D) Hemoglobin
Correct Answer: A) Albumin
7. A patient has a differential white blood cell count showing elevated levels of
neutrophils. Which physiological process is most likely occurring?
A) A parasitic infection
B) An acute bacterial infection
C) A viral infection
D) An allergic reaction
Correct Answer: B) An acute bacterial infection – Neutrophils are the first
responders to bacterial infections; their numbers typically rise sharply during the
acute phase of such an infection to phagocytose pathogens.
8. The formed elements of blood include all of the following EXCEPT:
A) Erythrocytes
B) Leukocytes
C) Thrombocytes
D) Lymphocytes
Correct Answer: D) Lymphocytes – Lymphocytes are a type of leukocyte (white
blood cell), not a separate category of formed elements. The three main formed
elements are erythrocytes (RBCs), leukocytes (WBCs), and thrombocytes
(platelets).
