Read the excerpt from the US Supreme court case Plessy v. Ferguson (1896).The statute of Louisiana, acts of 1890, c. 111, requiring railway companies carrying passengers in their coaches in that State, to provide equal, but separate, accommodations for the white and colored races, by providing two or more passenger coaches for each passenger train, or by dividing the passenger coaches by a partition so as to secure separate accommodations; and providing that no person shall be permitted to occupy seats in coaches other than the ones assigned to them, on account of the race they belong to; and requiring the officer of the passenger train to assign each passenger to the coach or compartment assigned for the race to which he or she belong; and imposing fines or imprisonment upon passengers insisting on going into a coach or compartment other than the one set aide for the race to which he or she belongs; and conferring upon officers of the train power to refuse to carry on the train passengers refusing to occupy the coach or compartment assigned to them, and exempting the railway company from liability for such refusal, are not in conflict with the provisions either of the Thirteenth Amendment or of the Fourteenth Amendment to the Constitution of the United States. Which best explains why the Supreme Court's decision in Plessy v. Ferguson was unconstitutional?The Supreme Court's ruling allowed states to deny equal protection to any person within its jurisdiction. Since the 14th Amendment did not make concessions for people born outside the US, the Supreme Court's decision could not be applied.The Supreme Court's decision gave individual states the freedom to make their own laws in relation to non-whites.Since segregation laws did not provide equal protections or liberties to non-whites, the ruling was not consistent with the 14th Amendment.

If we want our BP to go up, we need to _______ CO and ______ TPR. How do you increase TPR? -Blood Viscosity can increase by more RBC production-Blood Vessel Length can increase by gaining weight ^BOTH of these take a long time-Decreased vessel radius (vasoconstriction) ^Increases resistance on the SPOT (unlike both above) -->Tell all other vessels to constrict besides brain and heart to icnrease resistance therefore increasing BP. Give _________ (drug) to patient in order for this to happen. (causes vasoconstriction) How do you increase Cardiac Output? Increased HR & SVWhat increases heart rate? -Decrease parasympathetic impulses, increase sympathetic impulses(SNS=fight or flight=increased ehart rate)What increases SV? -Sympathetic nervous system causes stronger contraction, increasing SV-Increase __________ because SV is influenced by how much blood starts off in the ventricle. By increasing this, there will in turn be greater blood to the heart by venous return HOW to increase blood to the heart:-Increase blood volume -Skeletal muscle pump (exercising increases venous return! this is why people in attention can pass out, because they are not moving muscles)-Breathe (everytime you in breathe the pressure __________ in thoracic cavity. This draws more blood to the heart because it is in the thoracic cavity)-Veins have muscle that surrounds them/By constricting it will increase venous return, this constriction doesn't affect heart's blood flow and actually increases it! --> Increased venous return = Increased SV= Increased ____= Increased ______.
