Physiology Part 3 Flashcards
made in kidney, stimulate production of RBCs
erythropoietin
life expectancy of RBCs
120 days
storage from of Iron
ferritin
required vitamin for iron absorption
vitamin C
Leukocytes
Neutrophils (60%) Lymphocytes (30%) Monocytes (8%) Eosinophils (3%), Basophils (~0%)
“Never Let My Engine Blow 60-30-8-3-0”
Uncle BEN’s rice (types of granulocytes)
Basophils, Eosinophils, Neutrophils
liver macrophages
Kupffer cells
brain macrophages
microglia
stores calcium to be released in skeletal muscle
sarcoplasmic reticulum
“telephone line” that causes release of calcium for SR
T tubule
covers f-actin filament’s binding site
tropomyosin
binds calcium and move tropomyosin off binding site
found in skeletal and cardiac muscle
troponin
calmodulin
smooth muscle contraction
T/F: I band is smaller, and A band does not change (skeletal muscle)
True
Alpha ventral root fibers
extrafusal
gamma ventral root fibers
intrafusal
muscle contracts without joint movement
isometric
muscle contracts with joint movement
Isotonic/isokinetic
determined by number of muscle fibers recruited
strength of muscle
fast twitch
slow twitch
white;
red
impermeable to water
ascending loop of henle
ascites
abdominal swelling
fats digested
duodenum
anasarca
edema- whole body
Blood flow to kidney
Renal artery, interlobar, arcuate, interlobular, afferent arteriole, glomerulus, efferent arteriole, peritubular capillaries
(RIA In A GEP)
Bowman’s capsule
filtration
aldosterone in distal tubule
reabsorbs sodium and secretes potassium
“kicks the Ks out, sucks up the sodium”
mechanoreceptors for blood pressure in kidney
Juxtaglomerular cells
from zona glomerulosa, absorbs sodium, excretes potassium, result of renin-angiotensin system
Aldosterone
Angiotensinogen protein is made in…
liver
Angiotensin Converting Enzyme (ACE) is made in…
lungs
constricts blood vessels and causes the release of aldosterone leading to long term increased blood pressure by increased sodium absorption
angiontensin II
respiratory acidosis
hypoventilation
