Chapter 18 - Blood
1) Which type of tissue is blood?
a) muscle tissue
b) epithelial tissue
c) connective tissue
d) nervous tissue
e) nutrient tissue
Blood is a connective tissue
2) What does a hematocrit test measure?
a) percentage of white blood cells
b) percentage of red blood cells
c) percentage of buffy coat
d) percentage of platelets
e) blood plasma levels
A hematocrit test measures the percentage
of red blood cells in a blood sample
3) What is the average temperature and pH of
a) 38 °C and 7.0
b) 36 °C and 7.0
c) 36°C and 7.4
d) 38 °C and 7.4
e) 37°C and 7.4
The average temperature of blood is 38°C.
The average pH of blood is 7.4
4) In blood plasma the major group of plasma
protein is
a) Albumin
b) Globulins
c) Immunoglobulins
d) Fibrinogen
e) Hormones and proteins
Albumin- is the most abundant; it is about
54% of total plasma protein; Globulin is the
2nd most common, immunoglobulins are
gamma globulins that are subunits of
globulin, and fibrinogen are the least
common plasma protein.
5) Which of the following is not a function of
a) Regulating pH
b) Produces hormones
c) Transports nutrients, waste, and gases
d) Maintain homeostasis
e) Distribution of heat
Blood does not generate hormones, it
transports hormones.
6) Aplastic anemia is:
a) Deficiency of vitamin B12 and/or folate.
b) Poor absorption of vitamin B12.
c) Condition where there are deficient
numbers of RBC stem cells.
d) Production of an abnormal type of
e) Maturation of the RBCs does not proceed
Deficiency of vitamin B12 is megaloblastic
anemia, poor absorption of vitamin B12 is
pernicious anemia, production of abnormal
type of hemoglobin is sickle cell anemia,
and when maturation of the RBCs does not
proceed normally it is called thalassemia.
7) Elevated levels of hemocrit percentage in the
blood is define as
a) anemia
b) sickle cell anemia
c) polycythemia
d) hemophilia
e) thrombosis
polycythemia is the abnormal condition of
having too many red blood cells
8) Myeloid stem cells can develop into all of the
following cells except
a) Megakaryoblast
b) Proerythroblast
c) Myeloblast
d) Monoblast
e) Lymphoblast
Lmphoblasts for from lymphoid stem cells.

9) Hemolysis is
a) The process of blot clotting
b) when there isn't enough erythrocytes
present in the blood
c) The rupturing of red blood cells
d) filtration of hemoglobin through the
e) the creation of new blood cells from
multipotent hematopoietic stem cells in
bone marrow
hemolysis is the breaking down of red blood
10) What antibody is present in a person with blood
type O?
a) Anti B
b) Anti A
c) Anti O
d) Both anti A and Anti B
e) no antibodies present
Type O erythrocytes do not display A or B
antigens. Thus, anti-A or anti-B antibodies
that might be circulating in the patient’s
blood plasma will not encounter any
erythrocyte surface antigens on the
donated blood and therefore will not be
provoked into a response.
11) How many globin proteins make up a
hemoglobin molecule?
a) 1
b) 2
c) 3
d) 4
e) 0
A molecule of hemoglobin contains four
globin proteins, each of which is bound to
one molecule of the iron-containing
pigment heme
12) What is the first step when a blood vessel is
a) vascular spasm
b) thrombosis
c) platelet plug formation
d) hemopoiesis
e) coagulation
13) Which of the following is not a function of
a) Defense
b) Distribution of Heat
c) Produce Oxygen
d) Maintenance of Homeostasis
e) Transportation
The specific functions of blood include
defense, distribution of heat, and
maintenance of homeostasis.
14) The least abundant plasma protein is:
a) Albumin
b) Fibrinogen
c) Globulins
d) Immunoglobulins
e) Amino Acids
fibrinogen accounts for about 7 percent of
the total plasma protein volume.
15) Which Hemopoietic growth factor triggers the
development of megakaryocytes into platelets?
a) Thrombopoietin
b) Cytokines
c) Erythropoietin
d) Interleukins
e) Fibroblasts
Thrombopoietin, another glycoprotein
hormone, is produced by the liver and
kidneys. It triggers the development of
megakaryocytes into platelets.
16) What is Thalassemia?
a) sickling of red blood cell
b) inability to produce adequate amounts of
c) inability of blood clotting
d) a circulatory blockage
e) absence of albumins in blood
Thalassemia is a condition when adequate
amount of alpha and beta chains of
hemoglobin is not produced.

17) What is the condition called when mother's
antibodies attack and kill fetal RBCs?
a) Sickle cell anemia
b) Natural RBC killing disease
c) Fetal chemolysis
d) Hemolytic disease of Newborn
e) Erythroblastosis
When mother's antibodies pass through
placenta, attacks and kill fetal RBC, the
condition is called hemolytic disease of
Newborn (HDN)
18) Which Blood group is universal donor?
a) A+
b) B+
c) O-
d) AB+
e) A-
O+ blood group is universal donor as it has
neither antigen A nor antigen B
Chapter 19 - The Heart
19) Which structure separates the heart from other
mediastinal structures?
a) diaphragm
b) pericardium
c) right lung
d) thymus
e) trachea
Pericardium, refers to the tough membrane
which sits in the pericardial cavity and
separates the heart from other structures
within the mediastinum.
20) Number the steps of blood circulation in the
heart in order:
1). Blood enters left ventricle, which pumps it
into the systemic circuit.
2).Gas exchange occurs in pulmonary capillaries
3).Blood flows from right atrium to the right
ventricle, where it's pumped into pulmonary
4). Blood in pulmonary artery is low in oxygen
but relatively high in carbon dioxide.
5).Blood high in oxygen and low in carbon
dioxide returns to left atrium.
6). Carbon dioxide and oxygen exchange occurs
in the systemic capillaries & blood returns to
right atrium."
a) 3,1,2,4,5,6
b) 3,6,5,2,1,4
c) 1,6,2,5,4,3
d) 1,6,4,3,2,5
e) 3,4,2,5,1,6
Circulation of blood as described in
21) The right ventricle receive blood from the right
atrium via:
a) mitral valve
b) aortic valve
c) pulmonary valve
d) tricuspid valve
e) circumflex artery
left ventricle receives blood from left atrium
via mitral, B: aortic valve prevents backflow
from aorta & allows blood to leave heart, C:
pulmonary valve opens to allow blood to be
pumped from the heart to the lungs; D:
tricuspid valve allow blood to flow from
right atrium to right ventricle; E: supplies
blood to the left atrium, side and back of
the left ventricle
