Epithelial Tissue Quiz - Anatomy

Ava is learning about the different roles of tissues in the human body. She wants to know which of the following is NOT a function of epithelial tissue. Can you help her?

• Protection

• Absorption

• Contraction

• Secretion

Abigail is examining tissue samples under a microscope. She notices that some tissues have only one layer of cells, while others have multiple layers. What is the main structural feature distinguishing these two types of epithelium?

• Shape of cells

• Number of cell layers

• Presence of cilia

• Presence of microvilli

While examining a tissue sample under the microscope, Daniel notices that the cells form a continuous sheet and each cell has one side exposed to the environment or an internal space, while the opposite side is attached to underlying tissue. Which characteristic is true of all epithelial tissues regarding their surfaces?

• They have multiple nuclei in each cell

• They are avascular and lack nerve endings

• They possess both a free (apical) surface and a basal surface

• They contain abundant collagen fibers throughout

Kai is studying how different tissues in the body receive nutrients. He notices that some tissues, like the skin's outer layer, do not have visible blood vessels. Which of the following statements best describes why these tissues are considered "avascular"?

• Epithelial tissues have a rich supply of blood vessels.

• Epithelial tissues receive nutrients directly from blood flowing through their cells.

• Epithelial tissues lack blood vessels and rely on diffusion from underlying tissues for nutrients.

• Epithelial tissues generate their own blood supply through specialized cells.

Which of the following shapes is characteristic of squamous epithelial cells?

• Column-like

• Flat and scale-like

• Cube-shaped

• Star-shaped

Ava is studying how oxygen moves from the air sacs in the lungs into the blood. Which type of epithelial tissue is best suited for this process of diffusion and filtration?

• Simple squamous

• Stratified cuboidal

• Pseudostratified columnar

• Transitional

During a biology class, Mason observes a sample of epithelial tissue under the microscope and notices cells that are specialized for a particular function. Which of the following is the main function of goblet cells in epithelial tissue?

• Secretion of digestive enzymes

• Production of keratin

• Secretion of mucus

• Absorption of water

Sophia is studying the tissues found in different organs. She observes a tissue with tall, closely packed cells and wonders where she would most likely find simple columnar epithelium. Where is this tissue most likely located?

• Lining of the stomach

• Lining of the urinary bladder

• Outer layer of skin

• Lining of alveoli

While studying for her biology exam, Luna wonders which part of her body is lined with stratified squamous epithelium. Which of the following is a primary location where this type of tissue can be found?

• Lining of the small intestine

• Outer layer of the skin

• Lining of the trachea

• Lining of the urinary bladder

Charlotte is studying the structure of human skin in her biology class. She learns that the outermost layer of skin is described as a "keratinized" membrane. What does this mean?

• It is a membrane that produces mucus.

• It is a membrane composed of living cells only.

• It is a membrane that contains layers of dead cells filled with keratin for protection.

• It is a membrane specialized for absorption of nutrients.
