Organ Systems: The Integumentary System
Transcript of Organ Systems: The Integumentary System
Relationship With Other
We found the relationships with the following systems:
Major Organ/Structure Within the System and Their Structure
The major organs are:
Chosen Organ: Skin
The integumentary system protects the body from various kinds of damage.
by: Mahak, Arshnoor and Gurnoor 8C
Chosen Tissue: Epidermis
Role and Relationship to the Function of the Organ
Diseases and/or Treatments
Several different skin modelling initiatives exist which some are trying to research.
Abrasion; The process of wearing or scraping something away
Interferons; Proteins that block viral infection
Dentritic; Consisting of a branch-like form
Antigens; Foreign substances
Pathogens; Bacteria/virus/etc. that can create diseases
Squamous Epithelial Cells; Cells that function as mediators of filtration and diffusion for molecules like oxygen within the epidermis
Avascular; Doesn’t contain any blood or blood vessels
Keratinocytes; Cells in the epidermis which produce and store keratin
Melanocytes; Cells in the epidermis which produce melanin and protect the skin from ultraviolet radiation and sunburns
Langerhans Cells; Cells in the epidermis which detect and fight off pathogens.
Merkel Cells; Cells in the epidermis which connect nerve endings to the dermis to sense touch
Stem Cells; Cells which can create more similar cells and from which other kinds of cell are created by differentiation
Desmosomes; Spines in the stratum basale
Dermal Papillae; Finger-like extensions in the dermis that extend to the epidermis
Papillary Layer; Tissue in the dermis with dermis papillae (provides nutrients for the epidermis)
Reticular Layer; Deepest layer in the dermis which makes the skin stong/stretchy
Collagen/Elastin; Protien/Fiber in the reticular layer which makes the skin stretchy
Adipose Tissue; Stores energy in the form of triglycerides
Triglycerides; Organic compound formed from glycerol and three fatty acid groups
Follicle; Depression of epidermal cells; Stem cells within reproduce keratinocytes that form the hair while melanocytes produce pigment that gives the hair colour
Root; Within follicle; Cells in the root push to the skin surface to create hair
Shaft; Consists of hair parts outside the skin
Cuticle; Outermost layer made of keratinocytes
Cortex; Under the cuticle, the cells (cortex) form the majorit of the hair's width
Medulla; The innermost layer of hair; Contains pigmented cells full of keratin
Nail Matrix; The formative layer of cells at the base of the fingernail or toenail
Eponychium; The thickened layer of skin surrounding fingernails and toenails
Sebum; An oily secretion of the sebaceous glands.
Cerumen; Ear wax
Erector Pili Muscles; Small muscles which are attached to hair follicles shafts to change the insulation level produced by the hair.
Lipids; Organic compounds that are fatty acids and are soluble in organic solvents.
Depigmentation; Loss of pigmentation (coloring) in the skin or hair
If the Cells Were Unhealthy...
Protects body from:
abrasion (wearing out from outside)
detects pain, sensations, pressure and temperature
Role and Relationship to the Function of the Organ System
The function of the skin is to and protect cover the inner tissues, organs, and bones.
Fun: Interesting Facts
Your skin is known as your birthday suit.
You skin sends indicators.
Every month you have a whole new layer of skin.
Your nails grow .5mm per week.
You will shed 40lbs of skin in a lifetime.
You have 7 layers of flat, stacked cells.
The average amount of head hair is 120,000.
Your eyelids have the thinnest skin.
Hair grows 1cm per month.
An adult has 20 sq.ft of skin
Skin is the body's largest organ.
We lose 30,000 to 40,000 dead skin cells every minute!
Bed bugs exist solely to eat our dead skin.
The nails of the hand you use more often, grow faster! For right-handed people their right hand and for left handed people their left hand!
Some signs to know if cells are unhealthy:
Thinning, sagging, wrinkling and appearance of age spots on skin
Broken blood vessels
Areas of dryness, flecks of skn peeling off can be seen
Severe scale: Skin cancer is likely to occur while we age
Fungal Nail Infection
