Anatomy Chapter 5 Practice Quiz

The epithelial cells of the intestine absorb digested food molecules, vitamins, and ions

Absorbing substances

The plasma membranes of certain epithelial tissues contain carrier proteins that regulate the absorption of materials

Absorbing substances

The epithelium of the skin is a barrier to water and reduces water loss from the body

Acting as barriers

The epithelium of the skin prevents the entry of many toxic molecules and microorganisms into the body

Acting as barriers

Collagen fibers

Fibers that are flexible but resist stretching

Reticular fibers

Fibers that branch to form a supporting network

Elastic fibers

Fibers that can recoil to their original shape

Which of the following tissues has cells residing in lacunae?

Hyaline cartilage

Which statements characterize the ground substance of connective tissues?

It consists of proteins, carbohydrates, and water.; It can be fluid, semisolid, or solid.

Select all that apply to ground substance

It is nonliving; It may contain hyaluronic acid

What type of tissue supports epithelium?

Loose connective tissue

Simple squamous epithelium allows carbon dioxide to diffuse from the blood into the lungs

Permitting the passage of substances

The epithelium of the oral cavity protects the underlying structures from food as it is being chewed

Protecting underlying structures

The outermost layer of the skin (the epidermis) protects the underlying structures from the environment

Protecting underlying structures

Check all of the items that are possible functions of epithelial tissue

Protection; Absorption; sensation

Mucous glands and the enzyme-secreting portions of the pancreas secrete their products into ducts that subsequently deliver their products to other areas of the body

Secreting substances

Select all that are true of glands.

They may secrete substances to be eliminated from the body; They may be multicellular; They are composed predominantly of epithelial tissue; They may secrete substances for use elsewhere in the body

A gland may be composed of

a single cell

basement membrane

fluid connective tissue

blood

Osteocytes are residents of _________ tissue

bone

supporting connective tissue

bone and cartilage

All connective tissues contain three basic components:

cells, protein fibers, and ground substance

Tendons and ligaments are primarily made of

dense regular connective tissue

These glands have ducts and excrete their products onto the surface of the skin or into the lumen of hollow organs

exocrine

If a gland secretes its products through a duct to the surface of the small intestine epithelium, it must be an

exocrine gland

Cells that form fibers and ground substance in the extracellular matrix

fibroblasts

muscular tissue

heavily vascularized, which denotes high rates of energy consumption; excitable cells that are cylindrical, branching, or spindle shaped

Endocrine glands secrete products called ________

hormones

nervous tissue

includes excitable cells with numerous cellular extensions connecting adjacent cells to one another

connective tissue proper

loose and dense connective tissue

epithelial tissue

made up of glandular tissues; always maintaining a basement membrane and an apical surface; cells are sometimes well adapted for secretory and/or absorptive functions

connective tissue

most varied of the tissue types; serves as a transitional tissue between two different tissue types
