Question 1

Which of the following best describes the principle of complementarity of structure and function in anatomy and physiology?

Accepted Answer

Function always reflects structure; what a structure can do depends on its specific form.

Question 2

A scientist is studying the way the heart pumps blood by measuring electrical currents and pressure changes. Which subdivision of physiology is she most likely practicing?

Accepted Answer

Cardiovascular physiology

Question 3

Which of the following is the correct sequence of levels of structural organization in the human body, from simplest to most complex?

Accepted Answer

Chemical, cellular, tissue, organ, organ system, organismal

Question 4

Which process is illustrated by the second image, where platelets are attracted to a site of injury and amplify their own recruitment until a clot forms?

Accepted Answer

Positive feedback

Question 5

A patient has a blood glucose level that rises after a meal. Which of the following best describes the homeostatic response?

Accepted Answer

The pancreas releases insulin, causing cells to absorb glucose and lower blood glucose levels.

Question 6

Which of the following is NOT a component of a typical homeostatic control mechanism?

Accepted Answer

Amplifier

Question 7

Which subdivision of anatomy would focus on the microscopic structure of tissues?

Accepted Answer

Histology

Question 8

In the context of homeostasis, what is the primary role of the effector?

Accepted Answer

To provide the means for the control center's response to the stimulus

Question 9

Which of the following best explains why homeostatic imbalance increases the risk of disease as we age?

Accepted Answer

Negative feedback mechanisms become overwhelmed, and destructive positive feedback may take over.

Question 10

A researcher is using palpation and auscultation to study the human body. Which field is she most likely working in?

Accepted Answer

Anatomy

Question 11

Which of the following scenarios best illustrates the concept of negative feedback?

Accepted Answer

An increase in body temperature triggers sweating, which cools the body and lowers the temperature.

Question 12

Which of the following best describes the role of the control center in a homeostatic mechanism?

Accepted Answer

It determines the set point and analyzes input to coordinate an appropriate response.

Question 13

Which of the following is an example of a real-life positive feedback mechanism?

Accepted Answer

Enhancement of labor contractions by oxytocin

Question 14

Which level of structural organization is directly above the tissue level?

Accepted Answer

Organ

Question 15

A tennis player (as shown in the first image) is able to move his arm to hit the ball. Which levels of structural organization are involved in this action? (Select the most complete answer.)

Accepted Answer

Chemical, cellular, tissue, organ, organ system, and organismal levels

Question 16

Which of the following best describes the afferent pathway in a homeostatic control system?

Accepted Answer

It carries information from the receptor to the control center.

Question 17

Which of the following is a correct statement about the maintenance of homeostasis?

Accepted Answer

Homeostasis is a dynamic state of equilibrium maintained by all organ systems.

Question 18

Which of the following best explains why the study of basic chemical principles is important in physiology?

Accepted Answer

Because the body's abilities depend on chemical reactions in individual cells.

Question 19

Which of the following is an example of a homeostatic imbalance?

Accepted Answer

Heart failure due to destructive positive feedback

Question 20

Which of the following best describes the process of auscultation?

Accepted Answer

Listening to body sounds, such as the heartbeat, with a stethoscope
