Question 11.
In a freak accident, an overheated and dehydrated roofer
falls off the roof and onto a mirror that is being brought
into a construction site. The mirror breaks and cuts
several blood vessels, including the femoral artery. What
will happen to the roofer's NFP in his capillary beds?
Why?
ANSWER
If the roofer overheated, he probably had already lost a significant volume of
body fluid through perspiration as his body tried to cool off. That loss would
account for the dehydration. Loss of fluid without significant loss of solutes causes
the blood colloidal osmotic pressure (BCOP) to increase. The cuts the roofer
suffered would cause hemorrhaging and a loss of blood hydrostatic pressure
(BHP). If the BHP goes down and the BCOP goes up, the net filtration pressure
(NFP) should decrease because NFP = (BHP + IFOP) - BCOP. [IFOP is the
interstitial fluid osmotic pressure, which is so much smaller than the BHP or BCOP
that it Usually doesn't change NFP.
Question 12.
The volume of blood that circulates through the systemic
(or pulmonary) blood vessels per minute is called
a) stroke volume.
b) tidal volume.
c) cardiac output.
d) cardiac reserve.
e) total peripheral resistance
