Flashcards in Basic Anatomy and Physiology (8.8) Deck (41):
1

the study of structure

anatomy

2

the study of function

physiology

3

the basic unit of life

cell

4

these are composed from cells with common structure and function (4 types in most animals)

tissues

5

this tissue forms protective coverings of structures such as organs, cavities, and skin. They act as a barrier for various molecules. This tissue relies heavily on the cell junctions to function.

epithelial tissue

6

this tissue is for binding together and supporting the other tissues of the body

connective tissue

7

What are the 6 types of connective tissue?

Loose connective tissue, adipose tissue, fibrous connective tissue, cartilage, bone, blood tissue

8

this is the most abundant connective tissue. It basically acts as "filler material"

loose connective tissue

9

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

adipose tissue

10

these are composed of dense collagenous fibers

fibrous connective tissue

11

type of fibrous connective tissue that is for connecting bone to bone

ligaments

12

type of fibrous connective tissue for connecting bone with muscle

tendons

13

this is a flexible support material. This is the initial framework for making bone

cartilage

14

Osteo Tissues, this is made from cartilage that has undergone ossification

Bones

15

the process of making bone

ossification

16

this tissue connects the whole organism transporting genes, nutrients, wastes

blood tissue

17

type of blood tissue, the watery component containing dissolved substances

plasma

18

type of blood tissue, the cellular components- RBC's, WBC's, and platlets

hematocrit

19

means "red"

Erytho

20

means white

leuko

21

means cell

cyte

22

this tissue senses stimuli and relay messages

nervous tissue

23

the basic structure of nervous tissue

neurons

24

this part of the cell receives stimulus from the environment or another cell (neuron)

dendrites

25

this part collects and bundles the stimuli into one message (contains the organelles) (neuron)

body

26

this part takes the information away from the body toward the brain/muscle/gland. (neuron)

axon

27

this tissue provides a pulling force within the body

muscle tissue

28

cells of the muscle tissue are referred to as _______ ______ due to their long spindly shape.

muscle fibers

29

Muscle fibers are composed of _______ and ______ __________.

actin, myosin microfibrils

30

Muscle tissue is the second largest consumer of ______ in animals. (first is homeostasis)

energy

31

The three types of muscle tissue

skeletal, cardiac, and smooth

32

this is striated (stripped) muscle. It is voluntary meaning you can control it

skeletal

33

this is striated muscle. It is involuntary meaning the brain controls it, not you.

cardiac

34

this is unstriated muscle. It is involuntary and it functions in peristalsis

smooth

35

rhythmic contraction of the digestive tract or in moving blood through blood vessels

peristalsis

36

this functional structure is a collection of similar tissues working together

organs

37

The two cavities organs are positioned in

thoracic cavity, abdominal cavity

38

this is above the diaphragm. It contains the heart and lungs and is protected by ribs

thoracic cavity

39

this is below the diaphragm. It contains the digestive, urinary, and reproductive organs

abdominal cavity

40

these are composed of organs working together (there are 11 systems in animals)

organ systems

41

this is when all the organ systems are working together to create a multi-cellular organism (great example of emergent properties)

organism
