Document Summary

Osmosis: the tendency of a solvent to pass from a solution of lesser conc. to one of greater solute conc. when the two solutions are separated by a semipermeable membrane. This drives uid back into blood vessels, carrying away the metabolic waste byproducts of the tissues (carbon dioxide, etc. ). Normally, the uid gains and losses between the arteriolar and venular ends of the capillary bed are balanced, such that the net gains and losses of uid from the vasculature are equal. The lymphatic vessels eventually drain into the bloodstream, so the uid does return, just not at the level of the capillary bed. The hydrostatic force at the venular end of the capillary bed would be increased. Thus, the uid remains in the tissue spaces as edema. With lymphatic obstruction, initially small amounts of uid will remain in the interstitium.

There was a horrific traffic accident and you run to help the victims. You feel a pulse from his carotid artery ,however the medic comes along and gets no blood pressure as he measures it from the arm. He claims the victim is dead. You think which of the following?

A

Medic is not correct since it is the difference between heart rate and blood pressure that determines life. No heart rate only means tha the sympathetics have stopped vasoconstricting the blood vessels.

B

Medic is correct since it is common to not have a blood pressure of 120/80 and no pulse due to stress as was discussed in class.

C

Medic is incorrect since there is a pulse. This means the person is still alive.

D

Medic is correct since there is no blood pressure there is no life.
