Question 6

Which of the following cell shapes is best suited for absorption and secretion due to its increased cytoplasmic volume?

Accepted Answer

Cuboidal

Question 7

A researcher is examining a tissue under the microscope and observes a single layer of tall, rectangular cells. Which type of epithelial tissue is being observed?

Accepted Answer

Simple columnar epithelium

Question 8

Which of the following is a key distinguishing feature of stratified epithelial tissue compared to simple epithelial tissue?

Accepted Answer

Multiple layers of cells between the basal and apical surfaces

Question 9

If the rate of diffusion ($$D) $$across an epithelial layer is inversely proportional to the thickness ($$t) of $$the layer, which equation best describes this relationship?

Accepted Answer

$$D = \frac{k}{t}$$

Question 10

Which of the following real-life scenarios best illustrates the function of simple squamous epithelium?

Accepted Answer

The walls of capillaries allowing rapid exchange of oxygen and carbon dioxide

Question 11

Which tissue type is primarily responsible for covering body surfaces and lining internal cavities?

Accepted Answer

Epithelial tissue

Question 12

A pathologist identifies a tissue sample with cells that are wider than they are tall and arranged in a single layer. What is the most likely classification?

Accepted Answer

Simple squamous epithelium

Question 13

Which of the following statements about epithelial tissue is correct?

Accepted Answer

Epithelial tissue is avascular but innervated

Question 14

Which of the following is the correct sequence for identifying epithelial tissue based on the provided images?

Accepted Answer

Number of layers, then cell shape

Question 15

Which of the following best explains why simple squamous epithelium is found in areas of rapid exchange, such as alveoli and capillaries?

Accepted Answer

Its thin, flat cells minimize the distance for diffusion
