1

Describe the basic traits all animals share.

All multicellular heterotrophs by ingestion
No cell walls
Muscle and nervous tissue for movement and responding to the environment
Diploid dominant life styles

2

3 tissues (triploblastic), nervous system, looks the same on either side

bilateral symmetry

3

symmetrical around a radius (ex: starfish), 2 tissues (diploblastic), no muscle tissue

radial symmetry

4

makes the digestive organs/tract, liver, and lungs

Endoderm

5

makes skin and nervous tissue

ectoderm

6

makes muscles, bones, and the heart

mesoderm

7

back/top

dorsal

8

front/botton

ventral

9

toward the head

anterior

10

toward the tail

posterior

11

first opening animals (mouth develops first), first development of the digestive tract (Ex: Mollusks, Annelids, and Arthropods)

Protostomes

12

second opening animals (anus develops first), first development (Ex: Echinoderms , Chordates (includes humans))

Deuterostomes

13

uses our senses to detect environmental stimulus and cues as well as control bodily function

nervous system

14

moving the organism about the environment

muscular system

15

moving oxygen and nutrients through an organism’s whole body

circulatory system

16

to perform gas exchange with the environment (O2 in; CO2 out)

respiratory system

17

forms protective covering of structures, such as organs, cavities, and skin. They as a barrier for various molecules. Relies heavily on the cell junctions to function

Epithelial tissue

18

binding together and supporting the other tissues of the body

connective tissue

19

sense stimuli and relay messages. Basic structure is a neuron.

nervous system

20

provides a pulling force within the body. Cells of this tissue are called muscle fibers (composed of actin and myosin fibrils). Second largest consumers of energy.

muscle tissue

21

most abundant, acts as “filler material”

loose connective tissue

22

fat cells, these are for insulation, E storage, and padding

adipose tissue

23

composed of dense collagenous fibers

fibrous connective tissue

24

connect bone to bone

ligaments

25

connect bone with muscle

tendons

26

flexible support material, initial framework for making bone

cartilage

27

made from cartilage that has undergone ossification. These cells build bone by depositing Calcium and Magnesium salts in cartilage

Bone (osteo tissue)

28

connects the whole organism. Transports gases, nutrients, and wastes.

Blood Tissue

29

the watery component of blood tissue containing dissolved substances

plasma

30

the cellular component of blood tissue - RBC’s, WBC’s, and platelets

hematocrit
