Charles is an engineer who is evaluating a prototype of an artificial heart. The prototype beats in a
synchronized fashion, is hollow, and has tubes attached to it. It can be powered by electrical signals
from the brain when it is interfaced with the appropriate nerves.
What important feature should Charles notice the prototype is missing?
A. blood vessels to transport blood
B. a structure that would divide the hollow heart into chambers to separate oxygenated blood from
deoxygenated blood
C. a blood filtering mechanism to separate oxygenated blood from deoxygenated blood
D. a structure to pump blood through the valves - ANSWER: a structure that would divide the hollow
heart into chambers to separate oxygenated blood from deoxygenated blood
The diagram shows three steps in the clotting process.
Which lists the clotting process in the proper order?
A. A, C, B
B. B, A, C
C. C, A, B
D. B, C, A - ANSWER: B, C, A
Taking into consideration the function of the types of tissue and their integrated role in the how the
body works, which types of tissue play a role in protecting the body from internal and external
hazards?
I. epithelial
II. muscle
III. connective
IV. nervous - ANSWER: I, II, III, and IV
A student makes the analogy that the cardiovascular system is like a highway.
Why is this a good analogy? - ANSWER: A. Blood transports materials to and from different parts of
the body.
Jesse is studying a blood sample that has only antigen B on the red blood cells and antibody A in the
plasma.
What is the type of the blood sample? - ANSWER: B-
, When calcium levels in the blood are too low, the body releases a hormone that removes calcium
from the bones.
A person who suffers from a certain type of thyroid disease will often have low blood calcium and
brittle bones because the body is taking the calcium from the bones.
The afflicted person will typically see an endocrinologist, who studies hormones, and an orthopedist,
who studies bones.
What do these two doctors have in common? - ANSWER: They both focus on calcium levels.
The iris in the human eye contracts and expands, controlling the amount of light that reaches the
retina.
What types of muscle control this? - ANSWER: smooth and involuntary
Categorize the following into voluntary and involuntary muscles:
intestinal muscles, heart muscles, hand muscles, and neck muscles. - ANSWER: Intestinal and heart
muscles are involuntary muscles; hand and neck muscles are voluntary muscles.
A teacher makes the analogy that stem cell research did for medicine what the Internet did for
communication.
What is meant by this analogy? - ANSWER: Stem cell research led to a huge leap in medical science.
A sample of tissue has been observed to be tightly packed and regenerative. What type of tissue is the
sample? - ANSWER: epithelial
Which of the following actions involves voluntary muscle movement?
A. movement of food through the digestive tract
B. movement of blood through the blood vessels
C. beating of the heart
D. making of faces - ANSWER: making of faces
Which best compares and contrasts red blood cells and white blood cells?
A. Both are produced in the red bone marrow. Red blood cells transport oxygen, and white blood cells
protect the body against disease.
B. Both are produced in the red bone marrow. Red blood cells carry all blood components, and white
blood cells help the body heal cuts.
C. Both are made of hemoglobin. Red blood cells transport oxygen, and white blood cells protect the
body against disease.
D. Both are made of hemoglobin. Red blood cells carry all blood components, and white blood cells
help the body heal cuts. - ANSWER: Both are produced in the red bone marrow. Red blood cells
transport oxygen, and white blood cells protect the body against disease.
How does the cardiovascular system help the body maintain homeostasis? - ANSWER:
thermoregulation and hormone transport
How do hinge joints move? - ANSWER: They allow for simple angular movement
Which blood type can be transfused into a patient who has blood type A-? - ANSWER: O-
