platelet plug- the aggregation (aggregation=a cluster of things that have come or been brought together) of platelets in the initial phase of blood clotting Angiotensin System; how it works- Renin converts angiotensinogen, which is produced in the liver, to the hormone angiotensin I. Then ACE or angiotensin-converting enzyme found in the lungs metabolizes angiotensin I intoangiotensin II. Angiotensin II causes blood vessels to constrict and blood pressure to increase. Aldosterone- The adrenal gland is stimulated by stretch receptors to release aldosterone, which increases sodium reabsorption from the urine, sweat, and the gut. Through osmosis blood will eventually go back to normal. Renin- an enzyme secreted by and stored in the kidneys that promotes the production of the protein angiotensin.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
