How is epithelial tissue classified?
Epithelial tissue is classified by the number of cell layers (simple or stratified) and the shape of the cells (squamous, cuboidal, or columnar). What are two locations where stratified columnar epithelium can be found?
Stratified columnar epithelium can be found in the male urethra and the ducts of some glands. Which of the following is not a type of epithelial tissue? A) Simple squamous B) Stratified cuboidal C) Transitional D) Dense regular
D) Dense regular. Dense regular is a type of connective tissue, not epithelial tissue. Which tissue lines the oropharynx and laryngopharynx?
Stratified squamous epithelium lines the oropharynx and laryngopharynx, providing protection against abrasion. Which of the following has the thinner cell wall layer? A) Simple squamous B) Stratified squamous C) Transitional D) Simple columnar
A) Simple squamous. Simple squamous epithelium has the thinnest cell layer, facilitating diffusion. Which of the following does not contain ciliated cells? A) Trachea B) Fallopian tubes C) Alveoli D) Nasal cavity
C) Alveoli. Alveoli do not contain ciliated cells; they are lined with simple squamous epithelium. What do you think is the function of a villus?
The function of a villus is to increase the surface area for absorption, particularly in the small intestine. What body system contains pseudostratified columnar epithelium?
The respiratory system contains pseudostratified columnar epithelium, particularly in the trachea and bronchi. Which structures are fingerlike projections that greatly increase the absorbing surface of cells?
Villi are fingerlike projections that greatly increase the absorbing surface of cells, especially in the small intestine. The lining of the air sacs in the lungs (alveoli) is comprised of what epithelium?
The lining of the air sacs in the lungs (alveoli) is comprised of simple squamous epithelium. What type of epithelial tissue has the unique ability to stretch?
Transitional epithelium has the unique ability to stretch, accommodating changes in volume. Which of the following is not a function of epithelial tissues? A) Protection B) Secretion C) Contraction D) Absorption
C) Contraction. Contraction is a function of muscle tissue, not epithelial tissue. Which of the following is composed of multiple layers of cells? A) Simple squamous B) Stratified squamous C) Simple cuboidal D) Simple columnar
B) Stratified squamous. Stratified squamous epithelium is composed of multiple layers of cells. Which type of tissue covers internal and external body structures?
Epithelial tissue covers internal and external body structures, providing protection and selective permeability. Which type of epithelium is in the lining of the lung air sacs?
Simple squamous epithelium is in the lining of the lung air sacs, facilitating gas exchange. Which of the following is a function of epithelial tissue? A) Protection B) Contraction C) Support D) Storage
A) Protection. Epithelial tissue provides protection against mechanical damage and pathogens. Which of the following cells are spindle-shaped and have a single nucleus?
Smooth muscle cells are spindle-shaped and have a single nucleus. Which tissue forms the epiglottis?
Elastic cartilage forms the epiglottis, allowing it to bend and cover the trachea during swallowing. What is the main function of villi?
The main function of villi is to increase the surface area for absorption in the small intestine. Where is transitional epithelium found?
Transitional epithelium is found in the urinary bladder, ureters, and part of the urethra. What are the four primary tissue types in the human body, and which one is abbreviated as 'epithelia'?
The four primary tissue types are epithelial, connective, muscle, and nervous tissue. Epithelial tissue is commonly abbreviated as 'epithelia.' What is a key structural feature of epithelial tissue?
Epithelial tissue consists of tightly packed cells arranged in single or multiple sheets adjacent to open spaces. What is the primary function of covering and lining epithelium?
Covering and lining epithelium provides protection, regulates transport of substances, and allows sensations. What does it mean that epithelial tissue is selectively permeable?
It means the tissue regulates which substances can cross through it, allowing some to pass more easily than others. What is absorption in the context of epithelial tissue?
Absorption is the uptake of nutrients, such as glucose, from the environment into the body. What is filtration in the context of epithelial tissue?
Filtration is the separation of substances, a process especially important in the kidneys. What is glandular epithelium specialized for?
Glandular epithelium is specialized for forming glands that produce and release secretions. What is the relationship between epithelial tissue and glands?
Epithelial tissue forms the cellular structure of glands, enabling secretion of various substances. How does epithelial tissue in the airways function?
It lines the airways, providing protection and regulating the movement of substances in and out. How does epithelial tissue interact with nervous tissue to allow sensation?
Epithelial tissue detects external stimuli and activates nervous tissue, which processes the sensation. What is the main difference between covering and lining epithelium and glandular epithelium?
Covering and lining epithelium protects and regulates transport, while glandular epithelium specializes in secretion. Why is epithelial tissue important for temperature regulation?
It provides a protective barrier that helps shield underlying tissues from extreme temperatures. How does epithelial tissue contribute to the function of the digestive system?
It lines the digestive tract and absorbs nutrients from digested food. How does epithelial tissue regulate the movement of substances in the body?
By being selectively permeable, it controls which substances can pass through its layers. How does epithelial tissue participate in filtration in the kidneys?
It lines the kidney tubules, where it helps separate substances during urine formation. Why is epithelial tissue considered foundational to protection, secretion, and sensation?
Because its structure and functions enable it to serve as a barrier, produce secretions, and detect stimuli. How does glandular epithelium differ structurally from covering and lining epithelium?
Glandular epithelium forms specialized structures (glands) for secretion, while covering and lining epithelium forms protective sheets. How does epithelial tissue contribute to homeostasis?
By regulating transport, protecting against external factors, and producing secretions, it helps maintain internal balance. How does epithelial tissue help prevent dehydration?
By forming a barrier that limits water loss from body surfaces. How does epithelial tissue support immune defense?
By acting as a physical barrier to pathogens and sometimes producing antimicrobial secretions.
