Q: Which formula correctly represents the exchange of gases in the respiratory system?

$$\mathrm{O_2$} + \mathrm{CO_2$} \rightarrow \text{exchange with external environment}$$

Question 1

Which of the following best describes the difference between anatomy and physiology?

Accepted Answer

Anatomy focuses on the structure of organisms and their parts, while physiology focuses on the function of those parts.

Question 2

A patient suffers damage to the epithelial tissue lining their trachea. Which property of this tissue explains why it needs to be replaced frequently?

Accepted Answer

It is exposed to friction and mechanical stress, leading to frequent cell loss.

Question 3

Which organ system is responsible for the transport of nutrients, gases, wastes, cells, and other molecules throughout the body?

Accepted Answer

Cardiovascular system

Question 4

Which tissue type is characterized by cells embedded in an extracellular matrix that can be liquid, jelly-like, or solid?

Accepted Answer

Connective tissue

Question 5

A sample of tissue is found to be avascular and consists of multiple layers of flat cells. Which tissue is this most likely to be?

Accepted Answer

Stratified squamous epithelium

Question 6

Which of the following is a function of ciliated epithelial cells?

Accepted Answer

Increase surface area for membrane transport and sweep fluid or mucus

Question 7

Which connective tissue type is avascular and provides flexible support and cushioning in joints?

Accepted Answer

Cartilage (hyaline)

Question 8

A tissue sample contains oval cells arranged in concentric rings around a central canal, with a solid matrix of calcium salts and collagen fibers. What type of tissue is this?

Accepted Answer

Bone

Question 9

Which organ system is primarily responsible for the regulation of fluid balance and body defenses (immunity)?

Accepted Answer

Lymphatic system

Question 10

Which of the following best explains why poorly vascularized tissues heal more slowly than well-vascularized tissues?

Accepted Answer

Nutrients and oxygen must enter the tissue by diffusion, which may not be enough to reach the entire depth.

Question 11

Which formula correctly represents the exchange of gases in the respiratory system?

Accepted Answer

$$\mathrm{O_2$} + \mathrm{CO_2$} ightarrow 	ext{exchange with external environment}$$

Question 12

Which of the following is NOT a function of connective tissue?

Accepted Answer

Contract to produce voluntary movement

Question 13

A patient has a disorder affecting their endocrine system. Which of the following symptoms would most likely be observed?

Accepted Answer

Impaired hormone regulation affecting body functions

Question 14

Which of the following tissues is most likely to be found lining the alveoli of the lungs, where rapid gas exchange occurs?

Accepted Answer

Simple squamous epithelium

Question 15

Which organ system includes the skin, hair, and nails, and is responsible for temperature regulation and vitamin D synthesis?

Accepted Answer

Integumentary system

Question 16

Which of the following best describes the structure and function of loose areolar connective tissue?

Accepted Answer

Sparse cells in a loose collagen and elastin matrix; provides flexible support and absorbs fluid during swelling

Question 17

Which of the following is a function of the muscular system?

Accepted Answer

Contract to produce voluntary movement of skeleton and skin

Question 18

A tissue sample is found to have finger-like folds of cell membrane that increase surface area for membrane transport. What are these structures called?

Accepted Answer

Cilia

Question 19

Which of the following best describes the function of simple columnar epithelial tissue?

Accepted Answer

Secretion and absorption, especially in the digestive tract; may be ciliated to increase surface area

Question 20

Which of the following correctly matches the tissue type with its main components?

Accepted Answer

Connective tissue: cells and extracellular matrix
