Flashcards in 2-1 (8.30.16) Deck (45):
1

two major problems in environ health

1 pop pressure 2 climate change

2

two concepts related to pop pressure that need to know

1 carrying capacity 2 environ distress syndrome

3

define environ distress syndrome

1 deteriorate environ condition that threaten human health

4

give 2 ex of environ distress syndrome

1 reemergence of infectious disease and emergence of NEW disease; 2 loss of biodiversity

5

children are nose/mouth breathers

mouth

6

POP stands for

persistent organic pollutant

7

define POP

things that are NOT easily degraded by microbes

8

define superfund

a list of polluted locations requiring long term response to clean up hazardous stuff

9

end result of DDT (in timeline)

WHO said "increased support for DDT" to eliminate malaria

10

name of island in Japan affected by dancing cats

MINA-MATA

11

is mercury by itself bad?

no (read: conversion of mercury via algae = active, harmful form of mercury)

12

ambient means what

outdoors

13

two functional divisions of respiratory tract

conduction
respiration

14

two anatomic division of RT

upper
lower respiratory tract

15

pharynx refers to the area (anterior/posterior) to its namesake

posterior

16

# generations of branching in adult lung

23

17

which cells produce mucus

purpose of mucus

globlet cells

mucus traps particles -> these are moved via ciliary action

18

which is smaller: epiglottis OR trachea

epi

19

is trachea a C or O shape

C

20

the best way to distinguish terminal from respiratory bronchiole IS

alveoli

21

what part of lung pathway does gas exchange occur

alveoli

22

where is air blood barrier located

bt pul capillary and alveolus

23

define microcytosis

decrease size

24

what do you call variation in size

increased # of RBC is called

anisocytosis

polycythemia

25

what does hypochromic mean

paler than usual

26

def cyanotic

blue discoloration of skin

27

for RBC, what acts as antigens

CHO chains

28

list the blood antigens

A - antigen
B - antigen
A and B antigen

29

maturation in bone marrow of RBC takes # days

7 days

30

RBCs circulate in bloodstream for average # days

120 days

31

what progenitor cell produces:
-erythrocyte
-platelet

myeloid

32

in mid-gestation, these places are the predominant hematopoietic organs

-liver
-spleen

33

where is the primary site of blood formation in an ADULT (bigger category than bone marrow)

axial skeleton

34

where are RBCs destroyed

spleen

35

dif bt aspiration and biopsy

aspiration = removes marrow
biopsy = removes bone and marrow

1 precursor pool
2 storage pool
3 peripheral blood marginating and circulating pool
4 tissue pool

43

precursor to platelets

44

normal ratio of myeloid to erythroid

3:1
(ME)

45

how do megakaryocyte produce platelets

cytoplasmic fragmentation
