Cards

Term
tissue is ....
Definition
a group of cells working together to proform a common function
Term
List the (4) types of tissues.
Definition

Epithelial

 

Connective

 

Muscle

 

Nervous

Term
what are cancers classified by?
Definition

the type of tissue that it affects

 

( sarcomas)

(lukeima) blood cancer

Term
Epithelial( epithelium) Tissue
Definition

consist of tightly packed cells

they form a continuos layer

 

 

Term
Epithelial tissue is found where?
Definition

( it covers the outside of the body )

( it lines the organsand the body cavities )

 

Term
how is Epithelial tissue classified?
Definition
based on cells and shape and number of layers
Term
basement membrane
Definition
Term
# of layers
Definition

simple- 1 layer

stratified- more than 1

 

Term
Epithelial tissue FUNCTION
Definition

it to protect from microbateria entering the body

and the inner part (that lines our body cavities) secret mucus

Term
Gland( an epithelial tissue)
Definition

they secrete substances

 

ex) pancreas

Term

what are the two types of glands

 

( they can be one or the othe or can be both)

Definition

EXOCRINE:secrete into the duct and takes it somewhere else specific

 

ENDOCRINE: secrete into the blood stream

Term
Secrete into a duct
Definition
Exocrine gland
Term

secret into blood stream

 

Definition

Endocrine galnd

 

Term
Connective Tissue
Definition

Helps hold the organs together

support and protection

produces blood cells

and stores fat

 

 

Term
are connective tissue cells spread apart or connected tightly?
Definition

they are spread apart in a MATRIX

 

( the martrix- the cells are floating in this stuff, it is nocellular, is made up of fluids and other "stuff"and it can be very liquid or more concrete)

 

 

Term
Types of Conective Tissue
Definition

Loose Fibrous

Dense fibrous

Adipose (fat)

Cartilage

Bone

Blood*

Term

dense connective tissues

such as found in tendons, ligaments, and the dermis of skin.

Definition
Term
[image]
Definition
Term
Loose Fibrious
Definition
lungs, arteries
Term
Dense Fibrous
Definition
collagen, ligament, tendions - Strong,flexible
Term
addipose
Definition
fat
Term
cartilage
Definition
Dense fibrous- specialized

TYPES: Hyaline-nose, ribs
Elastic- ears
Fibrocartilage-knees, spine
Term
bone
Definition
most rigid ( is living tissue)
COMPACT - most of the strength
SPONGY - lacted near the end ( more flexible)

bone marrow is made in the shaft of the bones
Term
What is plasma
Definition
blood matrix
Term
What allows us to move
Definition
musscle tissue
Term
what is musscle tissue composed of?
Definition
Actin and myosin

( the interaction b/t the two allows movement)
Term
what are the three types of muscle tissue?
Definition
Cardiac
Skeletal
Smooth
Term
What is the muscle that makes up out heart?
Definition
Cardiac
Term
what allows the electirical impulses to flow (through the cardiac muscle) allowing our heart to work
Definition
intercaltaded disk
Term
What is the stiated muscle?
Definition
the skeletal muscle
Term
This muscle is also called the voluntary muscle.... why?
Definition
Skeletal muscle, because it can be consciously controlled.
Term
Which muscle is responsible for the body's involuntary muscle?
Definition
The smooth muscle
Term
The smooth muscle is...
Definition
not under voluntary control
Term
How many organ systems are there in the human body?
Definition
eleven Integumentary
Cardiovascular
Lymphatic &Immune
Digestive
Respiratory
Urinary
Skeletal
Muscular
Nervous
Endocrine
Reproductive system
Term
What is the skins main purpose?
Definition
maintains waterbalance(anything that leaves leaves throught secretion of our glands)

protects the internal organs(against infection, injury, and harmful sun rays)

Sensory organ( helping to control body temp)
Term
What are the two regions of the integumentary system?
Definition
1) epidermis
2) Dermis
Term
What is the outerlayer of the skin called?
Definition
the epidermis
Term
What is the deepest, innermost layer of skin?
Definition
The dermis
Term
What is contained in the dermis?
Definition
(Most of the skin's living structures)
sweat galnds, sensory receptors, hait follicles, arteries, veins
Term
What is contained in the epidermis?
Definition
sweat PORES, melanocytes
Term
What do hair shafts grow from?
Definition
Hair shafts grow from hair follicles situated in the dermis and subcutaneous tissue
Term
Subcutaneous tissue
Definition
is beneath the dermis
it is rich and fat and blood vessels
Term
Negative feedback control mechanisms (used by most of the body's systems) are called negative because the information caused by the feedback causes a reverse of the response. TSH is an example: blood levels of TSH serve as feedback for production of TSH.
Definition
Term
Positive feedback control is used in some cases.
Definition
Input increases or accelerates the response. During uterine contractions, oxytocin is produced. Oxytocin causes an increase in frequency and strength of uterine contractions. This in turn causes further production of oxytocin, etc.
Term
What does Homeostasis depend on?
Definition
the action and interaction of a number of body systems to maintain a range of conditions within which the body can best operate.
