Q: Which of the following is the correct formula for calculating body temperature in degrees Celsius if you know the temperature in degrees Fahrenheit?

$$C = (F - 32) \times \frac{5}{9}$$

Question 1

Which of the following best describes the Principle of Complementarity in anatomy and physiology?

Accepted Answer

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

Question 2

A patient is experiencing difficulty maintaining a stable internal body temperature after exposure to cold weather. Which necessary life function is most directly compromised?

Accepted Answer

Homeostasis

Question 3

Which of the following correctly lists the levels of structural organization in the human body from simplest to most complex?

Accepted Answer

Atom, molecule, organelle, cell, tissue, organ, organ system, organism

Question 4

A person is running a marathon and begins to sweat profusely. Which type of homeostatic feedback mechanism is primarily responsible for regulating their body temperature?

Accepted Answer

Negative feedback

Question 5

Which of the following is an example of positive feedback in the human body?

Accepted Answer

Enhancement of labor contractions by oxytocin

Question 6

A patient has a blood pH of 7.0 (normal is 7.35–7.45). Which homeostatic concept does this situation best illustrate?

Accepted Answer

Homeostatic imbalance

Question 7

Which of the following best defines 'anatomical position'?

Accepted Answer

Standing upright, facing forward, arms at sides, palms facing forward

Question 8

A surgeon makes a cut that divides the body into anterior and posterior parts. Which plane is this cut made along?

Accepted Answer

Frontal (coronal) plane

Question 9

Which of the following is NOT a necessary life function for humans?

Accepted Answer

Photosynthesis

Question 10

A patient is unable to maintain normal blood glucose levels after eating a meal. Which organ system is most likely malfunctioning?

Accepted Answer

Endocrine system

Question 11

If a person is lying on their back with their face upward, what is the anatomical term for this position?

Accepted Answer

Supine

Question 12

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

Accepted Answer

Receives input from receptors, processes the information, and determines the appropriate response

Question 13

A patient is diagnosed with a disease that causes the failure of negative feedback mechanisms. Which of the following is a likely consequence?

Accepted Answer

The risk of disease and homeostatic imbalance will increase.

Question 14

Which of the following is the correct formula for calculating body temperature in degrees Celsius if you know the temperature in degrees Fahrenheit?

Accepted Answer

$$C = (F - 32) 	imes \frac{5}{9}$$

Question 15

Which of the following best illustrates the concept of homeostasis?

Accepted Answer

The body increases heart rate during exercise and returns to resting rate after exercise ends.

Question 16

A patient is found to have a puncture wound in the thoracic cavity. Which major organ could be directly affected?

Accepted Answer

Heart

Question 17

Which directional term best describes the relationship of the nose to the ears?

Accepted Answer

Medial

Question 18

A cross-section through the abdomen that separates the body into superior and inferior parts is made along which plane?

Accepted Answer

Transverse (horizontal) plane

Question 19

Which of the following is a real-life example of negative feedback in the human body?

Accepted Answer

Release of insulin to lower blood glucose after eating

Question 20
