Edition Test Bank | Tortora and Derrickson
Questions
Chapter 1: An Introduction to the Human Body
1. This is the study of the functions of body structures.
a. Anatomy
b. Physiology
c. Dissection
d. Histology
e. Immunology
Answer: B
Rationale: Physiology is the study of the function of the body's structural
machinery.
2. This is defined as a group of cells with similar structure and function.
a. Tissue
b. Organ
c. Molecules
d. Compounds
e. Organism
Answer: A
Rationale: A tissue is a group of similar cells that work together to perform a
specific function.
3. Using your fingers to find your pulse on your wrist is an example of:
a. Auscultation
b. Palpation
c. Responsiveness
d. Gross anatomy
e. Physiologist
Answer: B
,Rationale: Palpation is the technique of examining the body by touch, often used
to feel a pulse.
4. Percussion techniques can be used to determine:
a. Heart beats
b. Pulse rate
c. Amplify sounds
d. Fluid in the lungs
e. Enlarged organs
Answer: D
Rationale: Percussion involves tapping on the body surface to listen to the
resulting sounds, which can help detect the presence of fluid or air in a body
cavity like the lungs.
5. This is the sum of all cellular processes that occur in the body.
a. Metabolism
b. Anabolism
c. Catabolism
d. Auscultation
e. Palpation
Answer: A
Rationale: Metabolism is the broad term for all chemical reactions and physical
processes that occur within the body.
6. This is the regulation of body conditions within normal limits.
a. Palpation
b. Percussion
c. Homeostasis
d. Autopsy
e. Histology
Answer: C
Rationale: Homeostasis is the maintenance of a relatively stable internal
environment despite external changes.
,7. The systems that provide homeostasis are:
a. Cardiovascular and Integumentary
b. Nervous system and Endocrine
c. Cardiovascular and respiratory systems
d. Respiratory and muscular systems
e. Urinary and integumentary systems
Answer: B
Rationale: The nervous system and endocrine system are the primary regulatory
systems that work together to control and coordinate other body systems to
maintain homeostasis.
8. This body fluid directly affects the proper functioning of cells.
a. Lymph
b. Blood
c. Interstitial fluid
d. Aqueous humor
e. Vitreous body
Answer: C
Rationale: Interstitial fluid is the fluid that surrounds the cells of the body. It is the
medium through which nutrients and wastes are exchanged between the blood
and the cells.
9. This is the structure of a feedback system that provides input to the control
center.
a. Receptor
b. Muscle
c. Brain
d. Effector
e. Efferent
Answer: A
Rationale: A receptor is a body structure that monitors changes in a controlled
condition and sends that information (input) to the control center.
, 10. A condition NOT regulated by a negative feedback loop would be:
a. Childbirth
b. Body temperature
c. Blood pressure
d. Heart rate
e. Blood sugar
Answer: A
Rationale: Childbirth is a classic example of a positive feedback loop, which
reinforces the initial stimulus, rather than reversing it like a negative feedback
loop.
11. This is a change in body function that can be measured objectively.
a. Symptom
b. Disorder
c. Disturbance
d. Disease
e. Sign
Answer: E
Rationale: A sign is an objective, measurable change in body function that can be
detected by a physician, such as a fever.
12. This is the structure of a feedback system that receives output from the
control center.
a. Receptor
b. Body fluids
c. Brain
d. Effector
e. Afferent
Answer: D
Rationale: An effector is a body structure that receives output from the control
center and produces a response to change the controlled condition.
13. In which cavity is the brain located?
a. Cranial cavity
