Unit 2 Lab Tissue Identification, Locations, and Functions

Flashcards covering tissue visual identification, body locations, and specific functions for Unit 2 Lab Exam preparation.

Simple Squamous Epithelium

A single layer of flattened cells that acts as a selective barrier allowing for the diffusion and filtration of secretions.

Simple Squamous Epithelium (Locations)

Air sacs in the lungs, lining of blood vessels, and lining of lymph vessels.

Simple Cuboidal Epithelium

Epithelial tissue composed of cube-shaped cells that functions in absorption and secretion.

Simple Cuboidal Epithelium (Locations)

Lining of the kidney tubules, surface of the ovaries, and ducts of endocrine glands.

Simple Columnar Epithelium

Tissue with single layer column-shaped cells that functions in absorption and secretion, secreting mostly mucus and assisting in oocyte movement through the uterine tube.

Simple Columnar Epithelium (Locations)

Lining of most of the gastrointestinal (digestive) tract (stomach, small intestine, large intestine), lining of the air passageways of the lung, and lining of the uterine tubes.

Pseudostratified Columnar Epithelium

Epithelial tissue that provides protection and promotes the movement of mucus along the lining of the respiratory tract.

Pseudostratified Columnar Epithelium (Locations)

Lining of the larger airways of the respiratory tract (nasal cavity, part of pharynx, parts of larynx, trachea, and bronchi), as well as lining part of the male urethra and epididymis.

Stratified Squamous Epithelium

Epithelium consisting of many layers of cells with a flat top layer, functioning to protect underlying tissue from abrasion.

Stratified Squamous Epithelium (Locations)

Lining of the oral cavity (mouth), part of the pharynx, part of the larynx, esophagus, lining of the vagina, and anus.

Transitional Epithelium

Flexible, elastic epithelium whose cells can look cuboidal or flat; accommodates urine volume changes by distending or relaxing.

Transitional Epithelium (Locations)

Lining of the urinary bladder, ureters, and part of the urethra.

Adipose Tissue

Anatomical term for fat tissue; functions to store energy, insulate, cushion, and protect.

Adipose Tissue (Locations)

Subcutaneous layer of the skin, as well as surrounding and covering some organs in the body.

Dense Irregular Connective Tissue

Durable tissue that withstands stresses applied in all directions.

Dense Irregular Connective Tissue (Locations)

Reticular layer of the skin, covers skeletal muscle, nerves, bone, cartilage, and some organ capsules.

Hyaline Cartilage

Cartilage tissue that provides support and forms most of the fetal skeleton.

Hyaline Cartilage (Locations)

Tip of the nose, trachea, bronchi, most of the larynx, costal cartilage of the ribs, ends of long bones, and most of the fetal skeleton.

Elastic Cartilage

Cartilage containing more fibers than hyaline cartilage; possesses the ability to stretch and recoil to maintain shape while permitting extensive flexibility.

Elastic Cartilage (Locations)

External ear and epiglottis of larynx.

Fibrocartilage

Least flexible cartilage with parallel collagen fibers; acts as a weight-bearing cartilage that resists compression and acts as a shock absorber.

Fibrocartilage (Locations)

Intervertebral discs, pubic symphysis, and menisci of knee joints.

Blood

The only liquid connective tissue; functions as transport for respiratory gases and movement of immune cells and various nutrients through the body.

Blood (Locations)

Found primarily within blood vessels and in the heart.

Skeletal Muscle

Muscle tissue primarily responsible for moving the skeleton and for thermoregulation.

Skeletal Muscle (Locations)

Attaches to bones or sometimes to skin.

Osseous Tissue

Tissue generally known as bone tissue; provides levers for body movement, supports soft body structures, protects organs, and stores calcium and phosphorus.

Osseous Tissue (Locations)

Bones of the body.

Nervous Tissue

Tissue containing neurons that receive, process, and transmit nerve impulses.

Nervous Tissue (Locations)

Brain, spinal cord, and nerves.
