1

structures

anatomy

2

functions

physiology

3

what is the relationship between anatomy and physiology

difficult to separate; form follows function

4

levels of organization

chemical (atoms- molecules)
cellular (skin cells)
tissue (epith)
organ (kidney)
organ system (digestive)
organism (human)

5

basic unit of life

cells

6

the existence of a stable internal environment

homeostasis

7

adjustment of physiological systems to preserve homeostasis

homeostatic regulation

8

what will happen if homeostasis is not preserved

illness or death

9

receives signals about changes in internal environment that causes response to reverse these changes back to the normal range

negative feedback ex. thermostat

10

cells and cell products organized into layers of groups that perform a relatively limited number of fxs

tissues

11

study of tissues

histology

12

cover internal and external surfaces; forms glands

epith

13

fill internal spaces and provide support for other tissues

connective

14

provide movement via contractions

muscle

15

conduct electrical impulses

neural

16

2 types of cell arrangements found in epith

microvilli and cillia

17

increases surface area for increase absorption and secretion

microvilli

18

sweep substances along epith surface

cilia

19

what is unique about transitional epith

transitions from thick to thin and back again as it stretches and recoils

20

where is transitional epith found

urinary bladder

21

collections of cells

glands

22

secretes hormones directly into interstitial fluid and/or blood

endocrine ex. pancreas

23

release secretions onto epith surfaces via ducts

exocrine ex. tears

24

function of mucus

lubrication

25

one unicellular exocrine gland? what does it secrete

mucous (goblet) cells; secretes mucins that w h2o forms mucus

26

most common conn tissue cell; make components of ground substances and fibers

fibroblasts

27

engulf pathogens and damaged cells

macrophages

28

fat cells

adipocytes

29

stem cells to divide and differentiate into other conn tissue cells

mesenchymal cells

30

3 types of cartilage

hyaline
elastic
fibro
