Summary Introduction
Introduction:
The process of excretion is very much important for the removal of waste from the body. The nitrogenous waste can be ammonia, urea and other toxic waste. The metabolite ammonia is toxic and is formed by the urea cycle in the liver. The ammonia molecule is toxic and to remove it from the body the organism require huge amount of water. Ammonia is the waste product of various fishes and aquatic organisms, and some terrestrial invertebrates and reptiles secrete uric acid. Urea is less toxic than ammonia.

What is the advantage of adding urea to feed in some cattle diets?
Select one:
a.
It helps reduce CH3 production and hence the amount of eructation which contributes to global warming
b.
It helps stimulate kidney activity to help reduce blood toxins
c.
Urea helps control the growth of unwanted fungi and protists
d.
It is a cheap way to increase protein production by rumen symbionts
If a small amount of urea were added to an isoosmotic saline solution containing cells, what would be the result?a. The cells would shrink and remain that way.b. The cells would first shrink but then be restored to normal volume aftera brief period of time.c. The cells would swell and remain that way.d. The cells would first swell but then be restored to normal volume after a brief period of time.e. The urea would have no effect, even transiently.
A patient has been vomiting for the last 3 days and has an abnormally low respiratory rate.
a. Why do you think they have a low respiratory rate?
b. What do you think has happened to the ECF volume and osmolarity over the last 3 days?
