Question 1

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

Accepted Answer

Question 2

A patient is experiencing a fever of 102°F. Which homeostatic mechanism is most likely to be activated to restore normal body temperature, and what is the sequence of events?

Accepted Answer

Negative feedback; receptor detects change, control center processes information, effector initiates cooling response

Question 3

Which organ system is primarily responsible for producing heat in the body, acting as the 'furnace'?

Accepted Answer

Muscular system

Question 4

If a person has a cut that is healing, which type of feedback mechanism is involved in the process of blood clotting?

Accepted Answer

Positive feedback

Question 5

Which directional term best describes the relationship between the carpal (wrist) and the antecubital (front of elbow) regions?

Accepted Answer

The carpal is distal to the antecubital

Question 6

Which organ system houses the cells that produce blood?

Accepted Answer

Skeletal system

Question 7

A patient is unable to maintain a constant internal pH. Which property of enzymes explains why this is dangerous?

Accepted Answer

Enzymes are proteins that lose their shape and function at extreme pH levels

Question 8

Which of the following is NOT a function of the lymphatic system?

Accepted Answer

Producing heat for the body

Question 9

Which abdominopelvic region would you expect to find the stomach?

Accepted Answer

Epigastric region

Question 10

Afferent pathways in homeostatic mechanisms are responsible for:

Accepted Answer

Sending input from the receptor to the control center

Question 11

Which of the following best describes metabolism?

Accepted Answer

All the chemical reactions that occur in the body

Question 12

If a cell undergoes differentiation, what is happening?

Accepted Answer

The cell is acquiring new structures and functions, becoming more complex and mature

Question 13

Which body plane divides the body into right and left halves?

Accepted Answer

Sagittal plane

Question 14

Which of the following is an example of movement as defined in physiology?

Accepted Answer

Movement of materials into, within, and out of the body

Question 15

Which directional term describes the position of the crural region relative to the sural region?

Accepted Answer

The crural is anterior or ventral to the sural

Question 16

Which of the following is a reason why living things require constant environmental conditions?

Accepted Answer

To ensure enzymes maintain their shape and function for metabolic reactions

Question 17

Which of the following is NOT a function of living things?

Accepted Answer

Decrease complexity of cells

Question 18

A patient is experiencing rapid labor contractions that increase in intensity and frequency. Which feedback mechanism is responsible for this process?

Accepted Answer

Positive feedback

Question 19

Which body cavity houses the brain and spinal cord?

Accepted Answer

Dorsal cavity

Question 20

If the set point for body temperature is $$98.6\ ^\circ \mathrm{F}$$, and the current temperature is $$100\ ^\circ \mathrm{F}$$, which equation best represents the change needed to restore homeostasis?

Accepted Answer

$$\Delta T = 100 - 98.6$$
