Chapter 26: Cardiovascular System
Salvo: Massage Therapy
MULTIPLE CHOICE
1. Which function does the cardiovascular system perform?
a. Digests, absorbs, and eliminates ingested substances
b. Produces heat, maintains posture, and produces movement
c. Combats hemorrhage and blood loss
d. Regulates reproduction and helps stress responses
ANS: C
The cardiovascular system transports substances, protects against pathogens, and combats
hemorrhage and blood loss.
2. Which characteristic describes blood?
a. Slightly cooler than normal body temperature
b. Thinner and less adhesive than water
c. Bright scarlet red to dull maroon in color
d. Slightly acidic pH
ANS: C
The red color of blood varies from bright scarlet to dull maroon, depending on its oxygen
content; the brighter the red, the more oxygen.
3. What determines whether blood is bright red or dull brick red in color?
a. Iron content
b. Platelet count
c. Oxygen content
d. Platelet count
ANS: C
The red color of blood varies from bright scarlet to dull maroon, depending on its oxygen
content.
4. Where are blood cells formed?
a. Liver and spleen
b. Red bone marrow
c. Hepatic portal system
d. Aorta and coronary sinus
ANS: B
Blood cell production, called hematopoiesis, occurs in red bone marrow. These cells include
erythrocytes, leukocytes, and thrombocytes.
5. Which term means blood cell production?
a. Hyperemia
b. Hematopoiesis
c. Remodeling
d. Ossification
, ANS: B
Blood cell production, called hematopoiesis, occurs in red bone marrow. These cells include
erythrocytes, leukocytes, and thrombocytes.
6. Which liquid are blood cells suspended in?
a. Lymph
b. Plasma
c. Interstitial fluid
d. Synovial fluid
ANS: B
Blood plasma is a straw-colored liquid in which blood cells are suspended. Blood plasma is
mostly water (between 90-95 percent), with substances including glucose, hormones,
dissolved proteins such as albumins and clotting factors such as fibrinogen.
7. What percentage of blood is plasma?
a. 10%
b. 25%
c. 55%
d. 90%
ANS: C
Blood plasma is a straw-colored liquid in which blood cells are suspended. Blood plasma is
mostly water (between 90-95 percent), with substances including glucose, hormones,
dissolved proteins such as albumins and clotting factors such as fibrinogen.
8. Which type of cells transports oxygen and carbon dioxide to and from body cells?
a. Platelets
b. Fibroblasts
c. Leukocytes
d. Erythrocytes
ANS: D
Erythrocytes, or red blood cells (RBCs), are the most numerous blood cell type. RBCs contain
a molecule called hemoglobin, giving blood its characteristic red color. Hemoglobin is an
iron-based protein that binds with oxygen and carbon dioxide so they can be transported in
blood.
9. Which type of cells contain hemoglobin?
a. Platelets
b. Fibroblasts
c. Leukocytes
d. Erythrocytes
ANS: D
RBCs contain a molecule called hemoglobin, giving blood its characteristic red color.
10. Proteins that are used to classify blood types are on the surfaces of which type of cells?
a. Platelets
b. Fibroblasts
c. Leukocytes
d. Erythrocytes
