Tissues

Question 1

Hierarchy of structure

Answer 1

cells>tissues>organ>organ system>organism

Question 2

explain the hierarchy of structure

Answer 2

-Tissues are made of collections of similar cells.
-Organs are made up of multiple tissues
-Organs and tissues work together to form organ systems
-multiple systems comprise an entire organism.

Question 3

4 primary tissue types

Answer 3

epithelial
-simple, stratified and secretory
connective
-blood, bone, cartilage, adipose, loose and dense
nervous
-motor, relay and sensory neuron
muscle
-skeletal, cardiac and smooth

Question 4

Where do you find epithelial tissues?

Answer 4

cover surfaces of the body.
e.g. skin, lining of the lungs, digestive tracts

Question 5

What is the function of epithelial tissues?

Answer 5

boundary layers, also aid absorption and secretion

Question 6

3 main epithelial cell shapes

Answer 6

squamous, cuboidal, columnar

Question 7

where are simple squamous cells shapes found

Answer 7

blood vessels, capillary walls, lungs

Question 8

where are stratified squamous cell shape found

Answer 8

skin lining

Question 9

where are transitional cell shapes found

Answer 9

bladder, urethra, prostate,

Question 10

epithelial surfaces, apical surface

Answer 10

side of the tissue exposed to the eternal environment

Question 11

epithelial surfaces, basal surface

Answer 11

the other side, that is attached to a connective tissue normally, called the basement membrane

Question 12

functions of loose connective tissues

Answer 12

provide padding and insulation

Question 13

functions of dense connective tissues

Answer 13

holds and binds body parts and other tissues together

Question 14

functions of specialised connective tissues

Answer 14

gives strength and protection

Question 15

loose connective tissues-adipose

Answer 15

fat under skin and around organs mainly heart, kidneys and mammery glands

Question 16

function of adipose

Answer 16

stores fat and provides insulation

Question 17

loose connective tissues-areolar

Answer 17

under all epithelial tissues

Question 18

areolar function

Answer 18

protects organs, blood vessels and nerves; allow passage for nerve and blood vessels through other tissues; gives strength to the epithelial tissue

Question 19

function of fibrous(ligaments) dense connective tissues

Answer 19

attaches bones to bones and provides support to joints

Question 20

function of elastic(tendons) dense connective tissues

Answer 20

attaches muscles to bones

Question 21

The matrix will often contain 1 or more of 3 types of fibres:

Answer 21

collagenous, elastic, reticular

Question 22

collagenous

Answer 22

very strong and make from protein called collagen

Question 23

elastic

Answer 23

stretchy and made from a protein called elastin

Question 24

reticular

Answer 24

from a mesh framework in glands and organs from a very fine type of collagen

Question 25

function of bone-specialised connective tissues

Answer 25

forms skeleton; protects and supports the main organs of the body

Question 26

function of cartilage- specialised connective tissues

Answer 26

smooth surfaces at joints and prevents collapse of trachea and bronchi

Question 27

function of blood- specialised connective tissues

Answer 27

transports substances around the body

Question 28

3 types of cartilage

Answer 28

hyaline, elastic and fibrous

Question 29

cartilage

Answer 29

-cells are called chondrocytes and secrete a matrix compromised of collage and elastin fibres.
-cells are found in gaps within the matrix called lacuna

Question 30

blood
