1. Yоu аre wаtching а 3-hоur mоvie about mid-20th century weapons manufacturing during the later stages of World War II. You decided to get a jumbo popcorn with extra salt. You neglected to order a drink. You are ¾ done eating the salty popcorn. Describe what occurs when the increased salt load hits your bloodstream. You should include in your essay the following information: a. The effect of increased salt on your blood b. The effect of increased salt on specific portions of your brain i. Where does the brain sense this change in osmolarity ii. Where specifically does the brain manufacture hormones specific to this osmolarity iii. Where does the brain secrete or not secrete hormones specific to this osmolarity iv. Why the change in osmolarity doesn’t cause massive cerebral edema or cerebral shrinking? v. What other compensatory mechanisms does the body use to help with the osmolarity that is in close proximity anatomically to the hormone production? c. What is the effect of the aforementioned hormone on the kidney (be specific about where the hormone is working)? d. What is the net effect in the body of changing your osmolarity through your diet (salt but no water)? e. Summarize how this process would be different if you never ate the popcorn but instead drank 2 gallons of water with no increase in solute load. What hormones are involved in that process?
