,BIOS 251 Exam 2 Anatomy & Physiology I Questions And Answers
2026/2027 Chamberlain
1.** Which of the following is a characteristic of epithelial tissue?
A) It is highly vascularized
B) It has a basement membrane
C) It has abundant extracellular matrix
D) It is innervated only by sensory nerves
**Correct Answer:** B) It has a basement membrane
**Rationale:** Epithelial tissue has a basement membrane that attaches it to
underlying connective tissue. It is avascular (A), has minimal extracellular
matrix (C), and is innervated by both sensory and motor nerves (D).
**2.** Which type of epithelial tissue is adapted for diffusion and filtration?
A) Simple squamous
B) Simple cuboidal
C) Simple columnar
D) Stratified squamous
**Correct Answer:** A) Simple squamous
**Rationale:** Simple squamous epithelium consists of thin, flat cells that
allow rapid exchange of gases and fluids. It is found in the alveoli of the
lungs and the lining of blood vessels (endothelium).
,**3.** Which epithelial tissue is found in the kidney tubules and glands?
A) Simple squamous
B) Simple cuboidal
C) Simple columnar
D) Stratified squamous
**Correct Answer:** B) Simple cuboidal
**Rationale:** Simple cuboidal epithelium consists of cube-shaped cells and
is found in kidney tubules and glands, where it facilitates secretion and
absorption.
**4.** Which epithelial tissue lines the digestive tract and has microvilli?
A) Simple squamous
B) Simple cuboidal
C) Simple columnar
D) Pseudostratified columnar
**Correct Answer:** C) Simple columnar
**Rationale:** Simple columnar epithelium lines the digestive tract and has
microvilli to increase surface area for absorption. It may also contain goblet
cells for mucus secretion.
**5.** Which type of epithelial tissue is found in areas subject to abrasion,
such as the skin?
, A) Simple squamous
B) Simple cuboidal
C) Simple columnar
D) Stratified squamous
**Correct Answer:** D) Stratified squamous
**Rationale:** Stratified squamous epithelium consists of multiple layers of
cells, providing protection against abrasion. It is found in the epidermis of the
skin, mouth, and esophagus.
**6.** Which epithelial tissue appears to be stratified but is actually a single
layer with nuclei at different levels?
A) Simple cuboidal
B) Simple columnar
C) Stratified squamous
D) Pseudostratified columnar
**Correct Answer:** D) Pseudostratified columnar
**Rationale:** Pseudostratified columnar epithelium appears stratified
because nuclei are at different levels, but all cells are attached to the
basement membrane. It is found in the respiratory tract and contains cilia
and goblet cells.
**7.** Which epithelial tissue is found in the urinary bladder and allows for
stretching?
