1

Chemoreflex ensures that CO2 elimination via the lungs

equals the production in the tissues

2

Carbonic anyhydrase assists the conversion of CO2 to

carbonic acid

3

What is dyspnoea?

is the different between stretch receptor feedback and chemoreceptor feedback

4

if there is a blood hemorrhage in the heart the pressures in the right/left ventricle/atria

all increase

5

What happens to heart rate with internal bleeding?

heart rate is higher than before to maintain normal blood flow to the brain

6

the delay between QRS complexes and ventricular systole is required for

excitation-contraction coupling process

7

Someone has severe internal bleeding they will have a ____ in plasma protein osmotic pressure because protein-free interstitial fluid will have moved into ____

decreased, capillaries

8

increase of Ang 2 constrict ____ arterioles and ___ GFR

efferent, increases

9

increased plasma ADH provokes ____ permeability of tubular epithelial cells of the nephron.

greater

10

How do you calculate creatinine clearance?

Ccr = Ucre. * Urine volume /plasma cre.

11

How do you calculate GFR via Inulin?

GFR = Urine inulin * Urine flow (or formation) / plasma inulin

12

during exercise, the increase in sympathetic output causes increased production of ?

aldosterone and vasopressin

13

T-cells, dendritic cells

19

Cells involved in both the innate and acquired immune systems are?

B cells, antibodies, NK, macrophages

20

What are the end products of fat digestion?

monoglycerides and free fatty acids

21

Slow, deep breathing

lowers venous admixture, increases arteriol oxygen saturation, decreases end-inspiration intrapleural pressure, reduces airway resistance to flow

22

When you vomit steadily your body fluids tend to become more
