16
Q

diffusion

A

movement of molecules from an area of high concentration to a lower concentration. doesnt require energy

17
Q

what is responsible for converting glucose and other nutrients into energy within a cell?

A

mitochondria

18
Q

what does tone do for the body

A

helps regulate blood pressure and maintain perfusion

19
Q

what is tone?

A

The amount of constriction in a blood vessel

20
Q

what happens when a blood vessel suffers a “loss of tone”

A

A decrease in blood pressure and perfusion

21
Q

shock

A

inability of the body to circulate blood the the body’s tissue and cells. Carbon dioxide will not be removed from the tissues

22
Q

Ventialtion/ perfusion mismatch

A

They are never exactly matched. Both happen without obstruction. When altered mismatch occurs

23
Q

when a capillary allows fluids to leave through its walls its said to be..

24
Q

what is the difference between respiration and ventilation

A

Ventilation- process of moving air in and out of lungs

Respiration- exchange of gasses between alveoli, RBCs and cells of the body

25
Preload
The amount of blood filling the ventricle of the heart prior to contraction
26
delayed capillary refill time is the sign of..
compensated shock
27
distributive shock what is lost
blood vessel tone
28
the product of tidal volume and ventilation rate is
minute volume
29
the effect of oxygen in the body
allows continuation of aerobic metabolism
30
person breathing too slowly will have
decreased minute volume
31
afterload
pressure the heart has to pump to force blood out into the system
