Q

What is cerebrospinal fluid

A

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

17
Q

Peripheral chemoreceptors in aorta and carotid artery also respond to?

A

CO2 and H+

18
Q

Too much CO2 and H+ can _________ breathing

19
Q

What are the functions of renal physiology

A
Excrete and remove nitrogen waste
Elimination and discharge of waste
Regulate blood volume and solute con.
            -water balance
            - sodium balance
           - pH balance
20
Q

What are the two functions of renal anatomy

A

2 kidneys

  • filter
  • reabsorb
  • secrete
  • excrete urine
21
Q

What does the urinary tract do?

A
Preforms elimination
Contains
    -ureters
    -bladder
    -urethra
22
Q

What is the ureters

A

Where urine is collected

23
Q

What is the bladder

A

Where urine is stored

24
Q

What is the urethra

A

Exit point to get out of urine system

25
What's the primary job of the kidneys
To filter blood
26
What's the flow in the kidneys
Blood--->filterate----->tubular fluid ------>urine
27
What precent of total cardiac output is blood filtered?
25%
28
Blood is delivered to cortex and then filtered where?
In glomerulus
29
Excreted fluids equal?
Filtered-reabsorb+secrete
30
What is the renal corpuscle made of
Glomerular (Bowmans) capsule | glomerulus
31
What is glomerular (Bowman) capsule
First structure in renal tubule
32
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
33
CO2 + H2O equal ?
H2CO3
