Epithelial Tissues

  • Epithelia comes in 2 forms:
  • Glandular epithelia
  • Membranous epithelia
  • Functions:
    • Protection
    • Absorption
    • Filtration
    • Excretion
    • Secretion
    • Sensory reception
slide3

Glandular Epithelia

Exocrine Gland

ducted glands

slide4

Glandular Epithelia

Exocrine Gland

ducted glands

Merocrine gland

Holocrine gland

slide5

Exocrine Gland

Goblet cells

slide6

Exocrine vs Endocrine Gland

Secretes product directly directly in blood

Secretes product through duct

slide8

Epithelial Tissues

  • Simple Squamous Epithelium
  • Simple Cuboidal Epithelium
  • Simple Columnar Epithelium
  • Stratified Epithelium
  • Pseudostratified Columnar Epithelium
  • Transitional Epithelium
simple squamous epithelium
Simple Squamous Epithelium

Function: gas exchange in lungs

Location: lines blood vessels, lymph vessels and various membranes within the thorax and abdomen

simple cuboidal epithelium
Simple Cuboidal Epithelium

Function: secretion and absorption

Location: kidney tubules

simple columnar epithelium
Simple Columnar Epithelium

Function: protection, secretion and absorption (associated

w/goblet cells-exocrine)

Location: lines uterus and digestive tract

simple columnar epithelium1
Simple Columnar Epithelium

1. Smooth muscle (long. layer)

2. Smooth muscle (circ. layer)

3. Simple columnar epithelium

4. Goblet cell

5. Lumen of the intestine

Cross section of small intestine

stratified squamous epithelium
Stratified Squamous Epithelium

Function: protects underlying cells from harmful env. effects

Location: covers skin, lines mouth and throat, vagina, and anal canal

stratified squamous epithelium1
Stratified Squamous Epithelium

1. Stratified squamous epithelium

2. Lumen of the esophagus

3. Connective tissue

Cross section of esophagus

pseudostratified columnar epithelium

goblet cell

Pseudostratified Columnar Epithelium

Function: secretion and propulsion of mucus

Location: lines respiratory and reproductive system

slide20

Stratified columnar

Function: protection and secretion

Location: rare in body, small amount in male urethra and in large ducts of some glands

slide21

Transitional

Function: stretches

Location: lines ureters, bladder and part of urethra

slide22

Cell Junctions

Contact points between the plasma membrane of tissue cells.

  • Tight Junction
    • fluid tight seal
    • prevents fluid from leaving a cavity
  • Anchoring Junction (adherens, desmosome & hemidesmosome)
    • tissues that stretch, ex. Heart muscle
  • Gap Junction
    • passage of chemical & electrical signals

connective tissues
Connective Tissues
  • Loose Connective Tissue
  • Dense Connective Tissue
  • Adipose Tissue
  • Cartilage
  • Bone
  • Blood
slide25

Connective Tissues

  • Functions:
  • Connects body parts
  • Protection
  • Insulation
  • Transport substances
  • Common characteristics:
  • All originate from mesenchyme
  • Well vascularized
  • Extracellular matrix
  • Three main elements:
  • Ground substance
  • Fibers
  • Cells

The Skin

An organ, cells constantly dying and being replaced

Facts:

Weighs 9-11 lbs

s.a. = 1.5-2m2

1 cm2 has 70 cm blood vessels, 55 cm

nerves, 100 sweat glands, 15 oil glands, 230 sensory receptors

New skin produced in 25-45 days

  • Is the radius proximal to the humerus?
  • Is the esophagus anterior to the trachea?
  • Are the ribs superficial to the lungs?
  • Is the urinary bladder medial to the ascending colon?
  • Is the sternum lateral to the descending colon?
  • A mature bone cell is called ____?
slide60

Inquiry

  • What is the difference between the three types of muscle tissue?
  • What type of epithelia tissue has many layers of flattened cells?
  • What layer in the epidermis are new skin cells produced?
  • What is the difference between endocrine and exocrine glands?
  • Which organ system includes the thymus and pancreas?
