Tissues

Question 1

Locations:
- air sacs of the lungs
- lining of heart
- linings of blood vessels and lymphatic vessels
Functions:
- allows materials to pass by diffusion and filtration can secrete lubrication
Tip:
- thinnest tissue in the body
- job is to allow passage of materials

Answer 1

Simple Squamous Epithelium

Question 2

Locations:
- Surface of the ovaries
- Kidney tubules
- Ducts and secretory portions of small glands
Functions:
- Secretion and absorption of materials

Answer 2

Simple Cuboidal Epithelium

Question 3

Locations:
- NONCILIATED –> lines most of the digestive tract
- CILIATED –> lines bronchi of lungs
- lines some regions of the uterus.
Functions:
- Secretion of mucus, digestive enzymes, and other substances
- Absorption of food molecules and other substances

Tip:
- same as simple cuboidal (Secretion/Absorption), but also more specific to digestive system

Answer 3

Simple Columnar Epithelium

Question 4

Location:
- epidermis (outside layer skin)
Function:
- protects underlying tissues in body areas subjected to abrasion

Answer 4

Keratinized Stratified Squamous Epithelium

Question 5

Location:
- esophagus, mouth, vagina
Function:
- protects underlying tissues in body areas subjected to abrasion

Answer 5

Non-keratinized Stratified Squamous Epithelium

Question 6

Location:
- CILIATED variety lines the trachea & most of the upper respiratory tract
- NONCILIATED type in male’s sperm-carrying ducts and ducts of large glands
Function:
- secrete substances (particularly mucus) - propulsion of mucus by cilia

Answer 6

Pseudostratified Epithelium

Question 7

Location:
- Rare in the body
- small amounts in male urethra
- large ducts of some glands
Function:
- protection and secretion
Tip:
- all of the stratified (squamous/cuboidal/columnar include protection function - makes sense since there are layers of cells

Answer 7

Stratified Columnar Epithelium

Question 8

Location:
- Largest ducts of sweat glands, mammary glands, and salivary glands
Function:
- protection

Answer 8

Stratified Cuboidal Epithelium

Question 9

Location:
- urinary tract (lines ureters, bladder, and part of the urethra)
Function:
- stretches readily
- permits distension of urinary organs by urine

Answer 9

Transitional Epithelium

Question 10

Location:
- Wraps and packages all organs
- Underneath the epithelial tissues (ET)
Function:
- Wraps and cushions organs
- Holds fluid
- Plays a role in inflammation

Answer 10

Loose (Areolar) Connective Tissue

Question 10

Location:

- Ligaments (bone to bone)
- Sclera (white part) of eye
Function:
- Resists tension in one direction

Answer 10

Dense Regular Connective Tissue

Question 11

Location:
- Dermis of Skin

Function:
- Able to withstand tension from many directions

Answer 11

Dense Irregular Connective Tissue

Question 12

Location:
- Bone Marrow
- Spleen
- Liver
- Lymph Nodes
Function:
- Its fibers form a soft skeleton to support cells (especially immune cells)

Answer 12

Reticular Connective Tissue

Question 13

Location:
- Skeleton
Function:
- Protection
- Levers for muscles to pull on
- Stores Calcium
- Site of blood cell production

Answer 13

Compact bone (osseous) Connective Tissue

Question 14

Location:

Function:
- Transport of respiratory gasses, nutrients, wastes, and other substances throughout body

Answer 14

Blood Connective Tissue

Question 15

Location:
- Nose
- Covers ends of bones
- Connects ribs to sternum
- Makes up rings of trachea
Function:
- Supports and reinforces
- Cushions
- Resists compression

Answer 15

Hyaline Cartilage

Question 16

Location:
- Ear
- Epiglottis (flap that keeps food out of your larynx/trachea)
Function:
- Maintains the shape of a structure while allowing great flexibility

Answer 16

Elastic Cartilage

Question 17

Location:
- Intervertebral discs (discs between vertebrae)
- Knee meniscus (discs in your knee)
- Pubic symphysis (holding your pelvis together)
Function:
- Great tensile strength with the ability to absorb compressive shock

Answer 17

Fibrocartilage Connective Tissue

Question 18

Location:
- Under the skin
- Breast
- Around: kidneys, eyeballs, heart
Function:
- Supports and protects organs
- Provides fuel reserves (stored energy)
- Insulates against heat loss

Answer 18
