Q: If the sum of all catabolic and anabolic reactions in the body is represented as $$M$$, which of the following best describes metabolism?

$$M = \text{catabolism} + \text{anabolism}$$

Question 1

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

Accepted Answer

What a structure can do depends on its specific form.

Question 2

A patient is unable to maintain a stable internal body temperature after exposure to cold. Which requirement for life is most directly compromised?

Accepted Answer

Homeostasis

Question 3

Which of the following is an example of a negative feedback mechanism in the human body?

Accepted Answer

Regulation of body temperature

Question 4

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

Accepted Answer

Tissue level

Question 5

A scientist is studying the microscopic structure of kidney tissue. Which subdivision of anatomy is she using?

Accepted Answer

Histology

Question 6

Which of the following best describes the function of the effector in a homeostatic control system?

Accepted Answer

Provides the means for the control center's response to the stimulus

Question 7

Which of the following is NOT one of the four basic tissue types in the human body?

Accepted Answer

Skeletal

Question 8

A person is experiencing rapid breathing and increased heart rate after running. Which life function is primarily responsible for adjusting these rates in response to activity?

Accepted Answer

Responsiveness

Question 9

Which of the following best explains why water is essential for life?

Accepted Answer

It provides the watery environment necessary for chemical reactions.

Question 10

If the sum of all catabolic and anabolic reactions in the body is represented as $$M$$, which of the following best describes metabolism?

Accepted Answer

$$M = 	ext{catabolism} + 	ext{anabolism}$$

Question 11

Which of the following scenarios best illustrates a homeostatic imbalance?

Accepted Answer

A person develops heart failure due to overwhelmed negative feedback mechanisms.

Question 12

Which organ system is primarily responsible for removing metabolic wastes from the body?

Accepted Answer

Urinary system

Question 13

A patient has a deficiency in vitamins and minerals. Which of the following is a likely consequence?

Accepted Answer

Impaired chemical reactions and structural problems

Question 14

Which of the following best describes the role of the receptor in a homeostatic control system?

Accepted Answer

It monitors the environment and responds to stimuli.

Question 15

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

Accepted Answer

Release of oxytocin to intensify contractions during childbirth

Question 16

Which of the following best explains why oxygen is a survival need for humans?

Accepted Answer

It is required for the release of energy from foods.

Question 17

A researcher is studying the electrical impulses that control muscle contraction. Which subdivision of physiology is most relevant to her research?

Accepted Answer

Neurophysiology

Question 18

Which of the following best describes the difference between afferent and efferent pathways in homeostatic control?

Accepted Answer

Afferent pathways carry information from the receptor to the control center; efferent pathways carry information from the control center to the effector.

Question 19

Which of the following is NOT a necessary life function?

Accepted Answer

Photosynthesis

Question 20

A patient is unable to break down ingested food into absorbable molecules. Which life function is most directly impaired?

Accepted Answer

Digestion
