Recently, athletes have begun to take advantage of the benefits of extra red blood cells, in a process known as `` blood doping`` (You can do your own research on it). Two weeks prior to a competition, a blood sample is taken and centrifuged, and the red blood cell component is stored. A few days before the event, the red blood cells are injected into the athlete. Why would athletes remove red blood cells only to return them to their bodies later? What problems could be created.
A patient was involved a serious accident and lost a large quantity of blood. In an attempt to replenish body fluids, plain water is added to the blood directly via one of his veins. What will be the most probable result of this transfusion?
a.
The patient's red blood cells will shrivel up because the blood has become hypotonic compared to the cells.
b.
The patient's red blood cells will swell and possibly burst because the blood has become hypotonic compared to the cells.
c.
The patient's red blood cells will shrivel up because the blood has become hypertonic compared to the cells.
d.
The patient's red blood cells will burst because the blood has become hypertonic compared to the cells.
You place a red blood cell in an unknown solution and it begins to swell then bursts. Which of the following can you correctly conclude?
a
the solution is hypotonic
b
the solution is hypoosmotic
c
both A and B
d
neither A nor B
