40.1 animal form and function

Question 1

body fluids

Answer 1

interstitial fluid
and
circulatory fluid

Question 2

function of body fluids

Answer 2

excrete waste and get nutrients

Question 3

basic animal systems

Answer 3

digestive

• circulatory
• respiratory
• excretory

Question 4

animal basic tissues

Answer 4

• epithelial
• connective
• muscles
• nervous

Question 5

epithelial cell shapes

Answer 5

cubodial
columnar
-squamous

Question 6

epithelial arrangements

Answer 6

simple

• stratified (multiple tiers of cells)
• pseudostratified (single layer that varies in cell height)

Question 7

what separates epithelial tissue from underlying tissues

Answer 7

basal surface and 
basal lamina (a dense mat of extracellular matrix)

Question 8

connective tissues

Answer 8

bind and support other tissues in the body

-consists of a asperse population of cells scattered through an extracellular matrix

Question 9

6 major types of connective tissue

Answer 9

loose

• cartilage
• fibrous
• adipose-stores fat -insulates
• blood
• bone

Question 10

connective tissue fibers

Answer 10

• collagenous–strength +flexibility (non elastic)
• elastic–easily stretched (resilient-snaps back to original position)
• reticular–thin and branched

for example, your skin doesn’t rip off b/c of collagenous and reticular, but it is resilient

Question 11

muscle tissues

Answer 11

skeletal muscle
(AKA straited muscle) -
–cardiac muscles –unconsious tasks (also straited)

–smooth muscle- involuntary actions (not straited)
found in digestive tract bladder, arteries etc.

Question 12

nervous tissue

Answer 12

sense stimuli and transmit signals

-send nerve impulses

Question 13

neurons

Answer 13

nerve cells

-have axons

Question 14

axons

Answer 14

extensions on neurons that transmit nerve impulses

Question 15

glial cells or glia

Answer 15

nourish
insulate
replenish neurons
