Lab Practical #1

Simple Squamous Epithelium

Allows materials to pass by diffusion and filtration; located in air sacs of lungs and lines the heart.

Simple Cuboidal Epithelium

Function is secretion and absorption; found in kidney tubules and ovary surfaces.

Simple Columnar Epithelium

Involved in absorption and secretion of mucus, enzymes, and other substances; lines the digestive tract.

Pseudostratified Columnar Epithelium

Secretes substances, particularly mucus; ciliated variety lines the trachea.

Stratified Squamous Epithelium

Protects underlying tissues that are subjected to abrasion; nonkeratinized type forms lines of the esophagus and mouth.

Stratified Cuboidal Epithelium

Provides protection; found in large ducts like sweat, mammary, and salivary glands.

Stratified Columnar Epithelium

Functions in protection and secretion; rare; found in the male urethra and large ducts of some glands.

Transitional Epithelium

Stretches and permits distension; lines ureters, urinary bladder, and part of the urethra.

Embyronic CT (Mesenchyme)

Gives rise to other connective tissue types; located in the embryo.

CTP, Loose CT (Areolar)

Wraps and cushions organs; located under epithelia.

CTP, Loose CT (Adipose)

Insulates against heat loss; supports and protects organs; found under skin, around kidneys, and eyeballs.

CTP, Loose CT (Reticular)

Supports other cells like white blood, mast, and macrophages; located in lymphoid organs.

CTP, Loose CT (Dense Regular)

Attaches muscle to bones or bones to bones; found in tendons and ligaments.

CTP, Loose CT (Elastic)

Allows recoil of tissue after stretching; found in walls of large arteries and ligaments in the vertebral column.

CTP, Loose CT (Dense Irregular)

Able to withstand tension in many directions; located in fibrous capsules of organs and joints, dermis.

Cartilage: Hyaline

Supports and reinforces; found in cartilage of nose, trachea, and larynx.

Cartilage: Elastic

Maintains shape while allowing flexibility; supports external ear (epiglottis).

Cartilage: Fibrocartilage

Provides tensile strength with the ability to absorb compressive shock; found in intervertebral discs and knee discs.

Bones

Function as levers for muscles; stores calcium and minerals; comprises bones.

Blood

Transports respiratory gases, wastes, and nutrients; located within blood vessels.
