Front 2

has a dorsal, hollw nerve chord, a notochord, pharyngeal pouche, a tail that extends the anus

Back 2

chordate

long supporting rod that runs just below the nerve cord

Back 3

notochord

Front 4

outher most layer that gives rise to sence organs nerves and the outher layer of skin

Back 4

2 chambered
1 atrium 1 ventrical
what has it?

Back 19

single loop ciculatiory system

fish

Front 20

3 chambered
1 vetrical 2 atrium
what has it?

Back 20

double loop ciculatory system

most reptiles

Front 21

4 chambered
2 atria 2 ventricals
what has it?

Back 21

double loop circulatory system

crocidaleans birds and mammels

Front 22

what is the path of a single loop circulatory system

Back 22

a atrium receives O2 poor blood from the body and a vetrical pumps O2 rich blood to the gills and onto the body

coordinates body movements

Front 28

what are two basic structures for gas exchange and resperation

Back 28

lungs and gills

Front 29

what else aids in respiration

Back 29

skin and lining of couth cavities (amphibians)
air sacs (birds)

Front 30

provide enormus surface area for gas exhanges

enabels mammels to take in large ammounts of oxygen

Back 30

aveoloi

Front 31

what is the difference of amphibian and reptilian respirtory systems?

Back 31

Amphibian - skin and gills at maternity and lungs and sking and lining of the mouth when mature

Reptile - spong lungs that take in more O2 and cant exchange gas threw skin

Front 32

what has the most effecient lungs

Back 32

birds

Front 33

blood travels from the heart to the gills then to the rest of the body and back to the heart

Back 33

single loop circulatory system

Front 34

1st loop carries blood between the lings while oxygen rich blood from the lung returns to heart

2nd loop carries blood between the heart and the bod

Back 34

double loop circulatory system
