Test 3.3 Flashcards
Carbonic acid is ?
Unstable and quickly breaks down
HCO3 + H equal ?
H2CO3
Bio carbonate can diffuse into blood and bind to?
Hb
True or false
Is this reaction fully reversible?
CO2 + H2O——-> H2CO3 ——> HCO3 + H
Yes
If Co2 increase in blood what happens to pH?
pH decease
If H+ concentration increases what happens to CO2?
CO increase
If CO2 decreases in blood what happens to pH?
pH increases
What is pH for blood
7.4
Is H+ more basic or acidic?
Acidic
Is NaOH more acidic or basic?
Basic
What does hypercapina means
Too much CO2
What does acidosis mean
Blood too acidic
What does hypocapina mean
Low concentration of CO2
What does alkalosis mean
Blood too basic
Central chemoreceptors in the brain detect changes to ?
H+ (pH)
What is cerebrospinal fluid
Fluid around brain
No RBC in brain
CO2 must be converted to H+ in RBC
H+ can diffuse from blood to CSF and active chemoreceptors
Peripheral chemoreceptors in aorta and carotid artery also respond to?
CO2 and H+
Too much CO2 and H+ can _________ breathing
Increase
What are the functions of renal physiology
Excrete and remove nitrogen waste
Elimination and discharge of waste
Regulate blood volume and solute con.
-water balance
- sodium balance
- pH balanceWhat are the two functions of renal anatomy
2 kidneys
- filter
- reabsorb
- secrete
- excrete urine
What does the urinary tract do?
Preforms elimination
Contains
-ureters
-bladder
-urethraWhat is the ureters
Where urine is collected
What is the bladder
Where urine is stored
What is the urethra
Exit point to get out of urine system
What’s the primary job of the kidneys
To filter blood
What’s the flow in the kidneys
Blood—>filterate—–>tubular fluid ——>urine
What precent of total cardiac output is blood filtered?
25%
Blood is delivered to cortex and then filtered where?
In glomerulus
Excreted fluids equal?
Filtered-reabsorb+secrete
What is the renal corpuscle made of
Glomerular (Bowmans) capsule
glomerulus
What is glomerular (Bowman) capsule
First structure in renal tubule
What is glomerulus and what occurs there
They are specialized blood vessels
- knots of capillaries - fluid and solute filtration, no gas exchange - blood enters via afferent arterioles - filtrate exist to capsule - remaining blood exists to efferent arterioles
CO2 + H2O equal ?
H2CO3
