12) Imagine a pulmonary embolus breaking up and entering thepulmonary artery supplying blood to an entire lobe of the leftlung, blocking 75% of the pulmonary arterioles in that lobe.Describe the effects on the arterioles and bronchioles in this lobein response to this event.
13) Elevated potassium levels in the body (hyperkalemia) is aserious condition, resulting in a severely decreased ability formuscle fibers and neurons to reploarize. The adrenal cortex canrespond to this. However, very high osmolarity shuts down thisresponse. Explain this incongruity, by describing the responsemechanism of the adrenal cortex. (6 pts)
16) ) A vaccine for Coronavirus is likely to take a longer timethan imagined, because the most obvious target of the vaccineshould be the external spike protein on the envelope of thisenveloped virus. The cellular attachment protein on epithelialcells, which the virus binds to for entry into the epithelial cell,is known to be ACE2, a receptor enzyme. Explain why the productionof a vaccine targeting the coronavirus spike protein (S1), is notlikely to be successful.
