Chapter 3 Part 2 Test

Front 1

groups of cells with a common structure and function

Back 1

tissues

Front 2

four main tissues in the body

Back 2

epithelium, muscle, connective, nervous

Front 3

functions of the epithelium

Back 3

1. protects us from outside world (skin)
2. absorbs (stomach and intestinal lining)
3. filters (kidney)
4. secretes (forms glands)

Front 4

traits of the epithelium

Back 4

1. closely attached to each other forming a protective barrier
2. always has one free surface open to outside the body or inside an internal organ
3. always had one fixed section attached to underlying connective tissue
4. has no blood vessels but can soak up nutrients from blood vessels in connective tissue underneath
5. can have lots of nerves in it (innervated)
6. very good at regenerating

Front 5

types of epithelium (shape)

Back 5

squamous, cuboidal, columnar

Front 6

squamous shape

Back 6

flat and scale-like

Front 7

cuboidal shape

Back 7

as tall as they are wide

Front 8

columnar shape

Back 8

tall, column shape

Front 9

types of epithelium (cell arrangement)

Back 9

simple epithelium, stratified epithelium

Front 10

what is simple epithelium?

Back 10

single layer of cells (usually for absorption and filtration)

Front 11

what is stratified epithelium?

Back 11

stacked up cell layers (protection from rubbing - mouth, skin)

Front 12

Functions of the connective tissue

Back 12

1. wraps around and cushions and protects organs
2. stores nutrients
3. internal support for organs
4. as tendon and ligaments protects joints and attached muscles to bone and each other
5. runs through organ capsules and in deep layers of skin giving strength

Front 13

3 elements of connective tissue

Back 13

1. ground substance - gel around cells and fibers
2. fibers- provide strength, elasticity and support
3. cells

Front 14

2 kinds of connective tissues

Back 14

loose connective tissue, dense connective tissue

Front 15

cushion around organs, loose arrangement of cells and fibers

Back 15

areolar connective tissue

Front 16

storehouse for nutrients, packed with cells and blood vessels

Back 16

adipose tissue

Front 17

internal supporting framework of some organs, delicate network of fibers and cells

Back 17

reticular connective tissue

Front 18

tendons and ligaments, regularly arranged bundles packed with fibers running same way for strength in one direction

Back 18

dense regular connective tissue

Front 19

skin, organ capsules, irregularly arranged bundles packed with fibers for strength in all directions

Back 19

dense irregular connective tissue

Front 20

3 special connective tissues

Back 20

cartilage, bone, blood

Front 21

cartilage functions

Back 21

1. provides strength w/ flexibility while resisting wear
2. cushions and shock absorbs where bones meet

Front 22

bone functions

Back 22

1. provides framework and strength for body
2. allows movement
3. stores calcium
4. contains blood-forming cells

Front 23

blood functions

Back 23

1. transports oxygen, carbon dioxide, and nutrients around the body
2. immune response

Front 24

nervous tissue functions

Back 24

1. conducts impulses to and from body organs via neurons

Front 25

3 elements of nervous tissue

Back 25

brain, spinal cord, nerves

Front 26

muscle tissue functions

Back 26

1. responsible for body movement
2. moves blood, food, waste through body's organs
3. responsible for mechanical digestion

Front 27

3 types of muscle tissue

Back 27

smooth, skeletal, cardiac

Front 28

organ walls and blood vessel walls, involuntary, spindle-shaped cells for pushing things through organs

Back 28

smooth

Front 29

large body muscles, voluntary, striated muscle packed in bundles and attached to bones for movement

Back 29

skeletal

Front 30

heart wall, involuntary, striated muscle with intercalated discs connecting cells for synchronized contractions during heart beat

Back 30

cardiac
