Chapter 41 Blood Cells
1) Blood is a type of connective tissue.
2) Which of the following cells and fragments in the blood lack a nucleus, and therefore, cannot reproduce?
A) Platelets only
B) Red blood cells and platelets
C) All types of white blood cells
D) Red blood cells only
E) Lymphocytes and monocytes
3) In a blood smear, the vast majority of formed elements are
A) white blood cells
B) neutrophils
C) platelets
D) leukocytes
E) red blood cells
4) Formed elements make up about 55% of the volume of the blood, and plasma makes up 45%.
5) Which of the following is not true of monocytes?
A) They make up 3–9% of the white blood cells.
B) They are the largest blood cells in the circulating blood.
C) They are phagocytes, which engulf and destroy microorganisms and dead cells.
D) They are classified as granulocytes.
E) All of these are true of monocytes.
6) Which of the following is not true of eosinophils?
A) They destroy parasites.
B) They are classified as granulocytes.
C) They produce antibodies.
D) They make up 1–3% of the white blood cells.
E) All of these are true of eosinophils.
7) Which of the following types of white blood cells is likely to increase in number in a person with cancer, chicken pox, or hypothyroidism?
A) Monocytes
B) Basophils
C) Neutrophils
D) Lymphocytes
E) Eosinophils
8) What is the main function of thrombocytes?
A) Hemostasis
B) Oxygen transport
C) Phagocytosis of bacteria
D) Control of inflammation
E) Dilation of blood vessels
9) The smallest type of white blood cell (only slightly larger than a red blood cell) is a
A) basophil.
B) monocyte.
C) eosinophil.
D) lymphocyte.
E) neutrophil.
10) Which of the following is not true of red blood cells?
A) The biconcave disc shape makes them look hollow in their centers.
B) They are also called erythrocytes.
C) They transport oxygen through the blood, but not carbon dioxide.
D) They contain hemoglobin for gas transport.
E) All of these are true of red blood cells.
11) Most, but not all, of the formed elements are produced in the red bone marrow.
12) If your differential white blood cell count contained 60% neutrophils, what could you conclude?
A) That you have an excess of neutrophils
B) That you might have a fungal infection
C) That you have a deficiency of neutrophils
D) That you might have an autoimmune disease
E) That you have a normal percentage of neutrophils
13) If your differential white blood cell count showed that you had 10% lymphocytes, what could you conclude?
A) That you have a deficiency of lymphocytes, or that another type of white blood cell is elevated
B) That you most likely have a parasitic worm infection
C) That your lymphocytes are in the normal range
D) That you have an excess of lymphocytes
E) That you most likely have tuberculosis
14) Besides bacterial infections, stress can be a cause of elevated neutrophils in the blood.
15) Sometimes the granules in the cytoplasm of neutrophils are so large, that the nucleus is almost hidden from view.
