Question 1

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

Accepted Answer

The structure of a body part enables and limits its function, and disruptions in structure usually result in adverse changes in function.

Question 2

A patient presents with a stab wound to the left lumbar region. Which organ is most likely to be affected?

Accepted Answer

Descending colon

Question 3

Which of the following best describes the anatomical position?

Accepted Answer

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

Question 4

Which directional term describes the relationship of the sternum to the heart?

Accepted Answer

Question 5

A coronal (frontal) plane divides the body into which sections?

Accepted Answer

Anterior and posterior

Question 6

Which feedback mechanism is most likely to maintain homeostasis when blood glucose levels rise after a meal?

Accepted Answer

Negative feedback, stimulating insulin release to lower glucose

Question 7

Which organelle is primarily responsible for ATP production in eukaryotic cells?

Accepted Answer

Mitochondrion

Question 8

A cell placed in a hypertonic solution will:

Accepted Answer

Lose water and shrink

Question 9

Which equation best represents the net movement of water during osmosis across a semipermeable membrane?

Accepted Answer

$$J = -P (C_1$ - C_2$)$$

Question 10

Which of the following is a function of the plasma membrane's glycoproteins?

Accepted Answer

Cell recognition and signaling

Question 11

Which type of epithelial tissue lines the alveoli of the lungs, allowing for rapid gas exchange?

Accepted Answer

Simple squamous

Question 12

Which connective tissue type contains a large amount of collagen fibers and is found in tendons?

Accepted Answer

Dense regular connective tissue

Question 13

Which cell junction prevents substances from passing between adjacent cells in epithelial tissue?

Accepted Answer

Tight junction

Question 14

A red blood cell is placed in a solution with an osmolarity of 400 mOsm/L. What will happen to the cell?

Accepted Answer

It will shrink due to water efflux.

Question 15

Which of the following best describes the function of microvilli on epithelial cells?

Accepted Answer

Increase surface area for absorption

Question 16

Which process requires energy input from ATP to move substances against their concentration gradient?

Accepted Answer

Primary active transport

Question 17

Which equation represents the rate of diffusion according to Fick's Law?

Accepted Answer

$$J = -D \frac{dC}{dx}$$

Question 18

Which organelle is responsible for packaging and modifying proteins for secretion?

Accepted Answer

Golgi apparatus

Question 19

Which tissue type is characterized by cells that transmit electrical impulses?

Accepted Answer

Nervous tissue

Question 20

A patient with severe burns loses the integrity of their skin's epithelial barrier. Which consequence is most likely?

Accepted Answer

Increased water loss and susceptibility to pathogens
