Tissue Quiz: Ultimate Knowledge! Trivia Test

1.

Epithelial tissue functions in protection, secretion, excretion, and absorption and is found covering body surfaces, internal organs, and compose glands.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Epithelial tissue is a type of tissue that covers body surfaces, lines internal organs, and forms glands. It plays a vital role in protecting the underlying tissues, organs, and body surfaces from mechanical injury, pathogens, and dehydration. Additionally, epithelial tissue is involved in the secretion of various substances, such as hormones and enzymes, excretion of waste products, and absorption of nutrients. Therefore, the statement that epithelial tissue functions in protection, secretion, excretion, and absorption is true.

Transitional epithelium is specialized to change in response to increased tension (distensibility, protection).
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Transitional epithelium is a type of tissue that lines the urinary bladder, ureters, and parts of the urethra. It is specialized to stretch and expand in response to increased tension, such as when the bladder fills with urine. This ability to change shape allows transitional epithelium to accommodate the varying volume of urine and protect the underlying tissues from damage. Therefore, the statement that transitional epithelium is specialized to change in response to increased tension is true.

Microvilli, which function to increase surface area, are more likely to be found in __________ epithelium.
- A.
  
  Simple cuboidal
- B.
  
  Simple squamous
- C.
  
  Simple columnar
- D.
  
  Transitional
Correct Answer
C. Simple columnar

Explanation
Microvilli are finger-like projections on the surface of cells that increase the surface area for absorption and secretion. They are commonly found in cells that are involved in absorption, such as the cells lining the intestines. Simple columnar epithelium is a type of tissue that consists of a single layer of column-shaped cells. This type of epithelium is often found in areas where absorption and secretion occur, such as the lining of the digestive tract. Therefore, it is more likely to have microvilli and increase surface area in simple columnar epithelium.

The outer layer of the skin is composed of ___________.
- A.
  
  Transitional epithelium
- B.
  
  Pseudostratified columnar epithelium
- C.
  
  Stratified squamous epithelium
- D.
  
  Stratified columnar epithelium
Correct Answer
C. Stratified squamous epithelium

Explanation
The outer layer of the skin is composed of stratified squamous epithelium. This type of epithelium is well-suited for protecting the underlying tissues from mechanical stress, abrasion, and pathogens. It is made up of multiple layers of flat, scale-like cells that provide a strong barrier against external factors. Additionally, stratified squamous epithelium is found in other areas of the body that require protection, such as the mouth, esophagus, and vagina.

The purpose of stratification in epithelial tissue is for extra ______________.
- A.
  
  Protection
- B.
  
  Secretion
- C.
  
  Excretion
- D.
  
  Absorption
Correct Answer
A. Protection

Explanation
Stratification in epithelial tissue is important for providing protection. The multiple layers of cells allow for increased strength and durability, making it more difficult for harmful substances or pathogens to penetrate the tissue. This stratification acts as a barrier, shielding the underlying tissues and organs from potential damage or infection.

What is the function of fibroblasts in connective tissue?
- A.
  
  Carry on phagocytosis
- B.
  
  Prevent blood clotting
- C.
  
  Secrete proteins that become fibers in the connective tissue matrix
- D.
  
  Release histamine to counteract allergies and inflammation
Correct Answer
C. Secrete proteins that become fibers in the connective tissue matrix

Explanation
Fibroblasts are responsible for secreting proteins that become fibers in the connective tissue matrix. These fibers, such as collagen and elastin, provide strength, support, and elasticity to the connective tissue. This function is crucial for maintaining the structural integrity and proper functioning of various organs and tissues in the body.
