1

made in kidney, stimulate production of RBCs

erythropoietin

2

life expectancy of RBCs

120 days

3

storage from of Iron

ferritin

4

required vitamin for iron absorption

vitamin C

5

Leukocytes

Neutrophils (60%) Lymphocytes (30%) Monocytes (8%) Eosinophils (3%), Basophils (~0%)

"Never Let My Engine Blow 60-30-8-3-0"

6

Uncle BEN's rice (types of granulocytes)

Basophils, Eosinophils, Neutrophils

7

liver macrophages

Kupffer cells

8

brain macrophages

microglia

9

stores calcium to be released in skeletal muscle

sarcoplasmic reticulum

10

"telephone line" that causes release of calcium for SR

T tubule

11

covers f-actin filament's binding site

tropomyosin

12

binds calcium and move tropomyosin off binding site
(found in skeletal and cardiac muscle)

troponin

13

calmodulin

smooth muscle contraction

14

T/F: I band is smaller, and A band does not change (skeletal muscle)

True

15

Alpha ventral root fibers

extrafusal

16

gamma ventral root fibers

intrafusal

17

muscle contracts without joint movement

isometric

18

muscle contracts with joint movement

Isotonic/isokinetic

19

determined by number of muscle fibers recruited

strength of muscle

20

fast twitch
slow twitch

white;
red

21

impermeable to water

ascending loop of henle

22

ascites

abdominal swelling

23

fats digested

duodenum

24

anasarca

edema- whole body

25

Blood flow to kidney

Renal artery, interlobar, arcuate, interlobular, afferent arteriole, glomerulus, efferent arteriole, peritubular capillaries

(RIA In A GEP)

26

Bowman's capsule

filtration

27

aldosterone in distal tubule

reabsorbs sodium and secretes potassium

"kicks the Ks out, sucks up the sodium"

28

mechanoreceptors for blood pressure in kidney

Juxtaglomerular cells

29

from zona glomerulosa, absorbs sodium, excretes potassium, result of renin-angiotensin system

Aldosterone

30

Angiotensinogen protein is made in...

liver

31

Angiotensin Converting Enzyme (ACE) is made in...

lungs

32

constricts blood vessels and causes the release of aldosterone leading to long term increased blood pressure by increased sodium absorption

angiontensin II

33

respiratory acidosis

hypoventilation
