1. A man involved in a traffic accident is rushed to the emergency room of a hospital with severe internal bleeding. Examination reveals a ruptured spleen. What is the treatment of choice and what is the likely long-term outcome (prognosis)? Due to the ruptured spleen, what is the patient most likely to die from in the short term and why?

2. Give two examples of antagonism in hormones and what these hormones act on.

Splenectomy is not as necessary as once believed, and is now performed less frequently. If the spleen does need to be removed, the prognosis is very good, as the functions of the spleen are taken over by the liver and bone marrow.


Glucagon and insulin are antagonistic hormones because they have opposing physiological actions on blood glucose levels.

Thank you Duddy you are the man!!!!

During a pulse-chase experiment, photographic emulsions were prepared at different times during the chase, and radioactive spots were detected at the following times and locations: 5 minutes: rough ER; 10 minutes: Golgi apparatus; 40 minutes: endosomes; 70 minutes: lysosomes; 140 minutes: lysosomes. Which of the following conclusions can be drawn from these results?

Proteins travelled from the endosome (40 minutes) to the lysosome (70 to 140 minutes).
